Comparing National Rankings: USA and China


America's Best Colleges
The US News America's Best Colleges (ABC) is very much the Grand Old Man of university rankings. Its chief data analyst has been described as the most powerful man in America although that is perhaps a bit exaggerated. These rankings have had a major role in defining excellence in American higher education and they may have contributed to US intellectual and scientific dominance in the last two decades of the twentieth century.

But they are changing. This year's edition has introduced two new measures of "social mobility", namely the number of  Pell Grant (low income) students and the comparative performance of those students. There is suspicion that this is an attempt to reward universities for the recruitment and graduation of certain favoured groups, including African Americans and Hispanics, and perhaps recent immigrants from the Global South. Income is used as a proxy for race since current affirmative action policies at Harvard and other places are under legal attack. 

It should be noted that success is defined as graduation within a six year period and that is something that can be easily achieved by extra tuition, lots of collaborative projects, credit for classroom discussions and effort and persistence, holding instructors responsible for student failure, innovative methods of assessment, contextualised grading and so on.

The new ABC has given the Pell Grant metrics a 5% weighting  and has also increased the weighting for graduation rate performance, which looks at actual student outcomes compared to those predicted from their social and academic attributes, from 7.5% to 8%. So now a total of 13 % in effect goes to social engineering. A good chunk of the rankings then is based on the dubious proposition that universities can and should reduce or eliminate the achievement gap between various groups.

To make room for these metrics the acceptance rate indicator has been eliminated, and the weightings for standardised test scores, high school rank, counsellor reviews and six year graduation rate have been reduced.

Getting rid of the acceptance rate metric is probably not a bad idea since it had the unfortunate effect of encouraging universities to maximise the number of rejected applications, which produced income for the universities but imposed a financial burden on applicants.

The rankings now assign nearly a one third weighting to student quality, 22% to graduation and retention rates and 10% for standardised tests and high school rank. 

It seems that US News is moving from ranking universities by the academic ability of their students to ranking based on the number and relative success of low income and "minority" students.

The latest ranking shows the effect of these changes. The very top is little changed but further down there are significant shifts. William and Mary is down. Howard University, a predominantly African American institution, is up as are the campuses of the University of California system.

ABC also has another 30% for resources (faculty 20% and financial 10%), 20% for for reputation (15 % peer and 5% high school counsellors), and 5% for alumni donations.

Shanghai Best Chinese University Rankings

The Shanghai Best Chinese University Ranking (BCUR) is a recent initiative although ShanghaiRanking has been doing global rankings since 2003. They are quite different from the US News rankings.

For student outcomes Shanghai assigns a weighting of 10% to graduate employment and does not bother with graduation rates. As noted, ABC gives 22% for student outcomes (six year graduation rate and first year retention rate). 


Shanghai gives a 30% weighting for the dreaded Gaokao, the national university entrance exam, compared to 10% for high school class rank and SAT/ACT scores in ABC.

With regard to inputs, Shanghai allocates just 5% for alumni donations, compared to 30% in the ABC for  class size, faculty salary, faculty highest degrees, student faculty ratio, full time faculty and financial resources. 

That 5% is the only thing in Shanghai that might  be relevant to reputation while ABC has a full 20% for reputation among peers and counsellors. 

Shanghai also has a 40% allocation for research, 10% for "social service", which comprises research income from industry and income from technology transfer, and 5% for international students. ABC has no equivalent to these, although it publishes rankings separately on postgraduate programmes.

To compare the two, ABC is heavy on inputs, student graduation and retention, reputation, and social engineering. Probably the last will become more important over the next few years 
BCUR, in contrast, emphasises student ability as measured by a famously rigorous entrance exam, student employment, research, links with industry, and internationalisation.

It seems that in the coming years excellence in higher education will be defined very differently. An elite US university will be one well endowed with money and human resources, will make sure that most of its students graduate one way or another, will ensure that that the  ethnic and gender composition of the faculty and student body matches that of America or the world, and has a good reputation among peers and the media.

An elite Chinese university will be one that produces employed and employable graduates, admits students with high levels of academic skills, has close ties with industry, and has a faculty that produces a high volume of excellent research.
