Surveys and Citations
I have just finished calculating the correlation between the scores for the academic survey and citations per faculty on the 2010 QS world University rankings.
Since the survey asked about research and since citations are supposed to be a robust indicator of research excellence we would expect a high correlation between the two.
It is in fact .391, which is on the low side. There could be valid reasons why it is so low. Citations, by definition, must follow publication which follows research which in turn is preceded by proposals and a variety of bureaucratic procedures. A flurry of citations might be indicative of the quality of research begun a decade ago. The responses to the survey might, on the other hand, be based on the first signs of research excellence long before the citations start rolling in.
Still, the correlation does not seem high enough. At first glance one would suspect that the survey is faulty but it could be that citations do not mean very much any more as a measure of excellence.
It would be very interesting to calculate the correlation between the score for research reputation on the Times Higher Education WUR and its citation indicator.
We would expect the THE survey to be more valid since the basic qualification for being included in the survey is being the corresponding author of an article included in the ISI indexes whereas for QS it is signing up for a journal published by World Scientific. But it can no longer be assumed that authorship of any article means very much . Does it always require more initiative and interest to get on the list of co-authors than to sign up for an online subscription?
It should also be noted that there is an overlap between the two surveys as both are supplemented with arts and humanities respondents from the Mardev mailing lists.
I have calculated the correlation between the citations indicator (normalised average citations per paper) in the THE 2010 rankings and the research indicator -- volume ( 4.5 % of the total score) income (6%) and reputation (19.5%)
This is .562, quite a bit better than the QS correlation . However, the research indicator combines a survey with other data.
It would be very interesting if THE and/or Thomson Reuters released the scores of the individual components of the research indicator.

Reputation, reputation, reputation!
As the world (or some of it) waits for the ranking survey forms to appear in its mail boxes, both THE and QS are promoting their surveys.
According to Phil Baty of THE:
"But in our consultation with the sector, there was strong support for the continued use of reputation information in the world rankings. Some 79 per cent of respondents to a survey by our rankings data provider Thomson Reuters rated reputation as a “must have” or “nice to have” measure. We operate in a global market where reputation clearly matters."
He then indicates several ways in which the THE survey is an improvement over the THE-QS, now QS, survey.
"We received a record 13,388 usable responses in just three months, making the survey the biggest of its kind in the world.
We promised a transparent approach. The methodology and survey instrument were published in full and this week, the thousands of academics who took part in the survey were sent a detailed report on the respondent profile. It makes reassuring reading:
• Responses were received from 131 countries"
It would, however, be interesting if the number of respondents from all countries were indicated. There are some people who wonder whether THE's sampling technique means that Singapore got the lion's share of responses in Southeast Asia.
Also, will THE publish the scores for the reputation surveys? At the moment they are bundled in with the other teaching and research indicators. What is the correlation between the score for research reputation and the citations indicator? Is there any sign that Alexandria, Bilkant or Hong Kong Baptist University have reputations that match their scores for research impact?
Meanwhile QS also has an item on its survey. They find that there is a similar demand for data on reputations.
"An impressive 79% of respondents, voted reputation for research as one of their top three criteria, with 60% choosing international profile of faculty, essentially another indicator of international reputation for research. This is in stark contrast to the 26% and 30% that prioiritised citations as a key measure.
Furthermore, when breaking these results out by broad faculty area, we can see consistent support across disciplines for the reputation measure but a marked dip in support for citations as a measure amongst respondents in the Arts & Humanities area – which tends to be the area least recognized by traditional measures of research output."

Comment on Internationalisation
International Focus, the newsletter of UK HE international Unit, has an article by Jane Knight on myths of internationalisation. The second myth is:
"Myth two rests on a belief that the more international a university is – in terms of students, faculty, curriculum, research, agreements, network memberships – the better its reputation is.
This is tied to the false notion that a strong international reputation is a proxy for quality. Cases of questionable admission and exit standards for universities highly dependent on the revenue and ‘brand equity’ of international students are concrete evidence that internationalisation does not always translate into improved quality or high standards.
This myth is further complicated by the quest for higher rankings on a global or regional league table such as the Times Higher Education or Academic World Ranking of Universities (AWRU). It is highly questionable whether the league tables accurately measure the internationality of a university and more importantly whether the international dimension is always a robust indicator of quality."
Also, it is much easier to be international in Switzerland or Singapore than in Central China or the Midwest of the US.

Penn State Law School
Malcolm Gladwell has an article in the current New Yorker about the US News and World Report college rankings. There is quite a lot there that I would like to discuss in another post. For the moment, I will just comment on an anecdote about the appearance of a non-existent law school in a ranking.
Gladwell descibes how Thomas Brennan, who edits a well known ranking of law schools, once sent out a questionnaire to other lawyers asking them to rank law schools and found that Penn State was, as Brennan is quoted as recalling, ranked around fifth. This was strange since there was no law school at Penn State until quite recently (1997 or 2000 in different sources).
This immediately struck me as odd since I remember a similar story about the Princeton Law School, which does not exist and which was also supposed to have made its appearance in a ranking.
The Princeton story is very probably apocryphal and might have begun with a comment by the dean of New York University Law School in the Dartmouth Law Journal that Princeton would appear in the top twenty law schools if a questionnaire was asked about it.
This story was plausible since it was an apparent example of the halo effect with Princeton's general excellence being reflected in the perception of a school that did not exist.
The problem with Brennan's account retold by Gladwell, which does not appear to be supported by documentary evidence, is that it requires that many lawyers should not only have mistakenly thought that Penn State had a law school (getting mixed up with the University of Pennsylvania?) but should have been in error about the general quality of the university. Penn State is nowhere near being a top ten or even a top fifty school.
Could this be another academic legend?

Impact Assessment
The use of citations as a measure of research quality was highlighted by the remarkable performance of Alexandria University, Bilkent University, Hong Kong Baptist University and others in the 2010 Times Higher Education World University Rankings. As THE and Thomson Reuters review their methodology, perhaps they could take note of this post in Francis' World Inside Out, that refers to a paper by Arnold and Fowler.
'“Goodhart’s law warns us that “when a measure becomes a target, it ceases to be a good measure.” The impact factor has moved in recent years from an obscure bibliometric indicator to become the chief quantitative measure of the quality of a journal, its research papers, the researchers who wrote those papers and even the institution they work in. The impact factor for a journal in a given year is calculated by ISI (Thomson Reuters) as the average number of citations in that year to the articles the journal published in the preceding two years. It is widely used by researchers deciding where to publish and what to read, by tenure and promotion committees laboring under the assumption that publication in a higher impact-factor journal represents better work. However, it has been widely criticized on a variety of grounds (it does not determine paper’s quality, it is a crude and flawed statistic, etc.). Impact factor manipulation can take numerous forms. Let us follow Douglas N. Arnold and Kristine K. Fowler, “Nefarious Numbers,” Notices of the AMS 58: 434-437, Mach 2011 [ArXiv, 1 Oct 2010].
Editors can manipulate the impact factor by means of the following practices: (1) “canny editors cultivate a cadre of regulars who can be relied upon to boost the measured quality of the journal by citing themselves and each other shamelessly;” (2) “authors of manuscripts under review often were asked or required by editors to cite other papers from the journal; this practice borders on extortion, even when posed as a suggestion;” and (3) “editors raise their journals’ impact factors is by publishing review items with large numbers of citations to the journal.” “These unscientific practices wreak upon the scientific literature have raised occasional alarms. A counterexample should confirm the need for alarm.” '

Looking East
Shanghai is planning to persuade two Ivy League schools, Cornell and Columbia, to set up branch campuses there. They already a branch of New York University.
Would anybody like to make a prediction when a new Oxford or Cambridge college will be established in Shanghai (or Singapore or Hong Kong)?
Or when an entire American university will move to China?

More dumbing Down
De Paul University will make it optional for applicants to submit SAT or ACT scores. Instead they can write short essays that demonstrate non-cognitive traits such as "commitment to service", "leadership" and "ability to meet long term goals".
The university says:
'"Admissions officers have often said that you can't measure heart," said Jon Boeckenstedt, associate vice president for enrollment management. "This, in some sense, is an attempt to measure that heart."
Mr. Boeckenstedt expects the change to encourage applicants with high grade-point averages but relatively low ACT and SAT scores to apply—be they low-income students, underrepresented minorities, or otherwise. Moreover, he and his colleagues believe the new admissions option will allow them to better select applicants who are most likely to succeed—and graduate.'
De Paul's administrators are being extremely naive if they think that these attributes cannot be easily coached or faked. Bluntly, how much effort does it take to teach a student what to say on one of these essays compared to squeezing out a few more points on the SAT?

We are all equal
I have come across an interesting article, "The equality of intelligence", in the philosopher's magazine by Nina Power. It is one of a series, "Ideas of the century" (I am not sure which one).
Power, whose dissertation is entitled From Theoretical Antihumanism to Practical Humanism: The Political Subject in Sartre, Althusser and Badiou and who is a senior lecturer at Roehampton University, refers to the work of Jacques Rancière,
Another example of her writing is Sarah Palin: Castration as Plenitude. Presumably that is potentially understandable by everybody.

"who never tires of repeating his assertion that equality is not just something to be fought for, but something to be presupposed, is, for me, one of the most important ideas of the past decade. Although Rancière begins the discussion of this idea in his 1987 text The Ignorant Schoolmaster, it is really only in the last ten years that others have taken up the idea and attempted to work out what it might mean for politics, art and philosophy. Equality may also be something one wishes for in a future to come, after fundamental shifts in the arrangement and order of society. But this is not Rancière’s point at all. Equality is not something to be achieved, but something to be presupposed, universally. Everyone is equally intelligent."Just in case you thought she was kidding:
"In principle then, there is no reason why a teacher is smarter than his or her student, or why educators shouldn’t be able to learn alongside pupils in a shared ignorance (coupled with the will to learn). The reason why we can relatively quickly understand complex arguments and formulae that have taken very clever people a long time to work out lends credence to Rancière’s insight that, at base, nothing is in principle impossible to understand and that everyone has the potential to understand anything."Power seems to be living in a different universe from those of us in the academic periphery. Perhaps she is actually pulling a Sokalian stunt but I suspect not. This sort of thing might be funny to many of us but it seems to be taken seriously in departments of education around the world. Just take a look at the model teaching philosophy statements found on the Internet.
Another example of her writing is Sarah Palin: Castration as Plenitude. Presumably that is potentially understandable by everybody.

More on Citations
A column in the THE by Phil Baty indicates that there might be some change in the research impact indicator in the forthcoming THE World University Rankings. It is good that THE is considering changes but I have a depressing feeling that Thomson Reuters, who collect the citations data, are going to have more weight in this matter than anyone or anything else.
Baty refers to a paper by Simon Pratt who manages the data for TR and THE.
Also, in the real world are there many universities that are excellent in a single field, defined as narrowly as theoretical physics or applied mathematics, while being mediocre or worse in everything else? Anyone who thinks that Alexandria is the fourth best university in the world for research impact because of its uncontested excellence in mathematics should take a look here.
There are also problems with normalising by region. Precisely what the regions are for the purposes of this indicator is not stated. If Africa is a region, does this mean that Alexandria got another boost, one denied to other Middle Eastern universities? Is Istanbul in Europe and Bilkent in Asia? Does Singapore get an extra weighting because of the poor performance of its Southeastern neighbours?
There are two other aspects of the normalisation that are not foregrounded in the article. First, TR apparently use normalisation by year. In some disciplines it is rare for a paper to be cited within a year of publication..In others it is commonplace. An article that is classified as being in a low citation field would get a massive boost if in addition it had a few citations within months of publication.
Remember also that the scores represent averages. A small number of total publications means an immense advantage for a university that has a few highly cited article in low cited fields and is located in a normally unproductive region. Alexandria's remarkable success was due to the convergence of four favourable factors: credit for publishing in a low citation sub-discipline, the frequent citation of recently published papers, being located in a continent whose scholars are not generally noticed and finally the selfless cooperation of hundreds of faculty who graciously refrained from sending papers to ISI indexed journals.
Alexandria University may not be open for the rest of this year and may not take part in the second THE WUR exercise. One wonders though how many universities around the world could benefit from these four factors and how many are getting ready to submit data to Thomson Reuters.

Baty refers to a paper by Simon Pratt who manages the data for TR and THE.
The issue was brought up again this month in a paper to the RU11 group of 11 leading research universities in Japan. It was written by Simon Pratt, project manager for institutional research at Thomson Reuters, which supplies the data for THE’s World University Rankings.This is correct but perhaps we should also consider whether the number of citations to papers in genetics is telling us something about the value that societies place on genetics rather than on mathematics and perhaps that is something that should not be ignored.
Explaining why THE’s rankings normalise for citations data by discipline, Pratt highlights the extent of the differences. In molecular biology and genetics, there were more than 1.6 million citations for the 145,939 papers published between 2005 and 2009, he writes; in mathematics, there were just 211,268 citations for a similar number of papers (140,219) published in the same period.
Obviously, an institution with world-class work in mathematics would be severely penalised by any system that did not reflect such differences in citations volume.
Also, in the real world are there many universities that are excellent in a single field, defined as narrowly as theoretical physics or applied mathematics, while being mediocre or worse in everything else? Anyone who thinks that Alexandria is the fourth best university in the world for research impact because of its uncontested excellence in mathematics should take a look here.

Training for Academics
The bureaucratisation of higher education continues relentlessly. Times Higher Education reports on moves to make all UK academics undergo compulsory training. This is not a totally useless idea: a bit of training in teaching methodology would do no harm at all for all those unprepared graduate assistants, part-timers and new Ph Ds that make up an increasing proportion of the work force in European and American universities.
But the higher education establishment has more than this in mind.

But the higher education establishment has more than this in mind.
Plans to revise the UK Professional Standards Framework were published by the HEA in November after the Browne Review called for teaching qualifications to be made compulsory for new academics.
The framework, which was first published in 2006, is used to accredit universities' teaching-development activities, but the HEA has admitted that many staff do not see it as "relevant" to their career progression.
Under the HEA's proposals, the updated framework says that in future, all staff on academic probation will have to complete an HEA-accredited teaching programme, such as a postgraduate certificate in higher education. Postgraduates who teach would also have to take an HEA-accredited course.
A "sector-wide profile" on the number of staff who have reached each level of the framework would be published by the HEA annually.A comment by "agreed" indicates just what is likely to happen.
Meanwhile, training courses would have to meet more detailed requirements.
I did one of these course a couple of years ago. I learnt nothing from the "content" that I couldn't have learnt in a fraction of the time by reading a book. The bulk of the course was an attempt to compel all lecturers to adopt fashionable models of teaching with no regard to the need for students to learn content. The example set by the lecturers on the course was apalling: ill prepared, dogmatic, and lacking in substance. A failure to connect with the "students" and a generally patronising tone was just one of the weaknesses. Weeks of potentially productive time were taken up by jumping through hoops and preparing assignments. This is not an isolated case, I know of several other such courses in other institutions that were equally shambolic. I'm all for improving the qulaity of teaching, but this is nonsensical. The only real benefit was the collegial relations with academics from other deaprtments forged through common bonds of disgust and mockery aimed at this ridiculous enterprise (presumably designed to justify the continued employment of failed academics from other disciplines given the role of teaching the reast of us how to teach).

Comparing Rankings 2
Number of Indicators
A ranking that contained only a single indicator would not be very interesting. Providing that the indicators are actually measuring different things, rankings with many indicators would contain more information. On the other hand, the more indicators there are the more likely it is that some will be redundant.
At the moment, the THE World University Rankings are in first place with 13 indicators and Paris Mines is last with only one. We should note, however, that the THE indicators are combined into 5 super-indicators and scores are given only for the latter.
So we have the following order.
1. THE World University Rankings: 13 indicators (scores are given for only 5 indicator groups)
2. HEEACT: 8 indicators
3= Academic Ranking of World Universities (Shanghai): 6 indicators
3= QS World University Rankings: 6 indicators
5. Leiden: 5 (strictly speaking, 5 separate rankings)
6= Webometrics: 4
6= Scimago Institutions Ranking: 4 (1 used for ranking)
8. Paris Mines Tech: 1

All Ears
Times Higher Education and Thomson Reuters are considering changes to their ranking methodology. It seems that the research impact indicator (citations) will figure prominently in their considerations. Phil Baty writes:
If anyone would like to justify these results they are welcome to post a comment.
I would like to make these suggestions for modifying the citations indicator.
Do not count self-citations, citations to the same journal in which a paper is published or citations to the same university. This would reduce, although not completely eliminate, manipulation of the citation system. If this is not done there will be massive self citation and citation of friends and colleagues. It might even be possible to implement a measure of net citation by deducting citations from an institution from the citations to it, thus reduce the effect of tacit citation agreements.
Normalisation by subject field is probably going to stay. It is reasonable that some consideration should be given to scholars who work in fields where citations are delayed and infrequent. However, it should be recognised that the purpose of this procedure is to identify pockets of excellent and research institutions are not built around a few pockets or even a single one. There are many ways of measuring research impact and this is just one of them. Others that might be used include total citations, citations per faculty, citations per research income and h-index.
Normalisation by year is especially problematical and should be dropped. It means that a handful of citations to an article classified as being in a low-citation discipline in the same year could dramatically multiply the score for this indicator. It also introduces an element of potential instability. Even if the methodology remains completely unchanged this year, Alexandria and Bilkent and others are going to drop scores of places as papers go on receiving citations but get less value from them as the benchmark number rises.
Raising the threshold of number of publications might not be a good idea. It is certainly true that Leiden University have a threshold of 400 publications a year but Leiden is measuring only research impact while THE and TR are measuring a variety of indicators. There are already too many blank spaces in these rankings and their credibility will be further undermined if universities are not assessed on an indicator with such a large weighting.
Times Higher Education and Thomson Reuters are considering changes to their ranking methodology. It seems that the research impact indicator (citations) will figure prominently in their considerations. Phil Baty writes:
In a consultation document circulated to the platform group, Thomson Reuters suggests a range of changes for 2011-12.It would be very wise to do something drastic about the citations indicator. According to last year's rankings, Alexandria university is the fourth best university in the world for research impact, Hong Kong Baptist University is second in Asia, Ecole Normale Superieure Paris best in Europe with Royal Holloway University of London fourth, University of California Santa Cruz fourth in the USA and the University of Adelaide best in Australia.
A key element of the 2010-11 rankings was a "research influence" indicator, which looked at the number of citations for each paper published by an institution. It drew on some 25 million citations from 5 million articles published over five years, and the data were normalised to reflect variations in citation volume between disciplines.
Thomson Reuters and THE are now consulting on ways to moderate the effect of rare, exceptionally highly cited papers, which could boost the performance of a university with a low publication volume.
One option would be to increase the minimum publication threshold for inclusion in the rankings, which in 2010 was 50 papers a year.
Feedback is also sought on modifications to citation data reflecting different regions' citation behaviour.
Thomson Reuters said that the modifications had allowed "smaller institutions with good but not outstanding impact in low-cited countries" to benefit.

Universities are being ranked according to the popularity of their Twitter accounts. According to an article in the Chronicle of Higher Education:
The top five are:
1. Berkeley (Surprise!)
2. Nottingham
3. York (Canada)
4. Northeastern
5. Cornell
Universiti Putra Malaysia is 6th and Universitas Indonesia 15th.

Cambridge and Harvard
After the break with THE, QS decided to continue the old methodology of the 2004-2009 rankings. At least, that is what they said. It was therefore surprising to see that, according to data provided by QS, there were in fact a number of noticeable rises and falls between 2009 and 2010 although nothing like as much as in previous years.
For example the University of Munich fell from 66th place to 98th place, the Free University of Berlin from 70th to 94th and Stockholm University from 168th to 215th while University College Dublin rose from 114th to 89th and Wurzburg from 309th to 215th.
But perhaps the most remarkable news was that Cambridge replaced Harvard as the world's best university. In every other ranking Harvard is well ahead.
So how did it happen? According to Martin Ince, “Harvard has taken more students since the last rankings were compiled without an equivalent increase in the number of academics.”
In other words there should have been a lower faculty student ratio and therefore a lower score for this indicator. This in fact happened. Harvard’s score went from 98 to 97.
Ince also says that there was an “improvement in staffing levels”, at Cambridge, presumably meaning that there was an increase in the number of faculty relative to the number of students. Between 2009 and 2010 Cambridge’s score for the student faculty remained the same at 100 which is consistent with Ince’s claim.
In addition to this, there was a "significant growth in the number of citations per faculty member" for Cambridge. It is not impossible that the number of citations racked up by Cambridge had risen relative to Harvard but the QS indicator counts citations over a five year so even a substantial increase in publications or citations would take a few years to have an equivalent effect on this indicator. Also note that this indicator is citations per faculty and it appears that the number of faculty at Cambridge has gone up relative to Harvard. So we would expect any increase in citations to be cancelled out by a similar increase in faculty.
It looks a little odd then that for this indicator the Cambridge score rose from 89 to 93, four points, which is worth 0.8 in the weighted total score. That, by the way, was the difference between Harvard and Cambridge in 2009.
The oddity is compounded when we look at other high ranking universities. between 2009 and 2010 Leiden's score for citations per faculty rose from 97 to 99, Emory from 90 to 95, Oxford from 80 to 84, Florida from 70 to 75.
It would at first sight appear plausible that if Harvard, the top scorer in both years, did worse on this indicator then everybody or nearly everybody else would do better. But if we look at universities further down the table, we found the opposite. Between 2009 and 2010 for this indicator Bochum fell from 43 to 34, Ghent from 43 to 37, Belfast from 44 to 35 and so on.
Could it be that there was some subtle and unannounced change in the method by which the raw scores were transformed into indicator scores. Is it just a coincidence that the change was sufficient to erase the difference between Harvard and Cambridge?

Comparing Rankings
International university rankings are now proliferating in much the same way that American rankings have multiplied over the last few decades although so far there is no global equivalent to top party schools or best colleges for squirrels.
It is now time for a cursory review and comparison of the major international rankings. I will omit recent rankings, those that look as though they may not be repeated or those that provide insufficient information about methodology.
The list is as follows:
Academic Ranking of World Universities
Higher Education Evaluation and Accreditation Council of Taiwan
International Professional Ranking of Higher Education Institutions (Paris Mines Tech)
Leiden Ranking
QS World University rankings
Scimago Institutions Ranking
THE World University Rankings
Webometrics Ranking of World Universities
The first attribute to be considered is simply the number of universities ranked. A ranking might have an impeccable methodology and analyse a score of indicators with the strictest attention to current bibliometric theory and statistical technique. If, however, it only ranks a few hundred universities it is of no use to those interested in the thousands left outside the elite of the ranked.
I am counting the number of universities in published rankings. Here the winner is clearly Webometrics, followed by Scimago.
Webometrics 12,300
Scimago 1,955
QS WUR 616
ARWU 500
HEEACT 500
Leiden 500
THE WUR 400
Paris Mines 376

Shanghai Ranks Macedonia
I am not sure how accurate the folowing report is. The whole of Macedonia has never had a Nobel or Fields award winner or an ISI highly cited researcher, has published fewer articles than Loughborugh University and has no articles in Nature or Science. It is difficult to see just what a team of seven from Shanghai would evaluate, especially since ARWU is reluctant to get involved with teaching quality or publications in the arts and humanities. Still, it is perhaps indicative that a European country has turned to China to evaluate its universities.

"Shanghai Jiao Tong University, which analyzes the top universities in the world on quality of faculty, research output quality of education and performance, has been selected to evaluate the public and private institutions for higher education in Macedonia, Minister of Education and Science Nikola Todorov told reporters on Sunday.
The ranking team included the Shanghai University Director, Executive and six members of the University's Center, Todorov said, pointing out that Macedonia is to be the first country from the region to be part of the the Academic Ranking of World Universities (ARWU), commonly known as the Shanghai ranking.
"The Shanghai ranking list is the most relevant in the world, and being part of it is a matter of prestige. We shall be honored our institutions for higher education to be evaluated by this university. This is going to be a revolution in the education sector, as for the first time we are offered an opportunity to see where we stand in regard to the quality," Todorov said"

The Disposable Academic
An article in the Economist (print edition, 18-31/12/2010, 146-8) analyses the plight of many of the world's Ph Ds. Many can expect nothing more a succession of miserable post-doc fellowships, short-term contracts or part-time jobs teaching remedial or matriculation classes. And those are the lucky ones who actually get their diploma.
It seems that the financial return for a Ph D is only marginally higher than that for a master's. Since there are undoubtedly variations by institution and discipline, it follows that for many joining a doctoral program is a losing proposition in every way.
One wonders whether countries like South Africa and some in Southeast Asia are creating future problems in the drive to boost the production of Ph Ds.

Value for Money
An article by Richard Vedder describes how the publication of data by Texas A and M University shows enormous variation in the cost of faculty members per student taught.
An article by Richard Vedder describes how the publication of data by Texas A and M University shows enormous variation in the cost of faculty members per student taught.
I recently asked my student research assistant to explore this data by choosing, more or less at random, 40 professors of the university's main campus at College Station — including one highly paid professor with a very modest teaching load in each department and one instructor who is modestly paid but teaches many students. The findings were startling, even for a veteran professor like myself.There are of course questions to be asked about whether the data included the supervision of dissertations and the difficulty of the courses taught. Even so, the results deserve close scrutiny and might even be a model for some sort of international comparison.
The 20 high-paid professors made, on average, over $200,000 each, totaling a little over $5 million annually to the university. These professors collectively taught 125 students last year, or roughly $40,000 per student. Since a typical student takes about 10 courses a year, the average cost of educating a student exclusively with this group of professors would be about $400,000, excluding other costs beyond faculty salaries.

Dumbing Down of University Grades
An article in the London Daily Telegraph shows that the number of first and upper second class degrees awarded by British universities has risen steadily over the last few decades. Their value to employers as an indicator of student quality has accordingly diminished.
David Barrett reports that:
We might note that the THE-QS rankings until 2009 and the QS rankings of last year have probably done quite a lot to encourage complacency by consistently overrating British universities especially Oxbridge and the London colleges.

David Barrett reports that:
The latest data shows that the criteria for awarding degrees has changed dramatically - despite complaints from many universities that grade inflation at A-level has made it hard for them to select candidates.
Traditionally, first class honours have been awarded sparingly to students who show exceptional depth of knowledge and originality.
But the new figures add further weight to a report by MPs last year which found that "inconsistency in standards is rife" and accused vice-chancellors of "defensive complacency".
