The NRC graduate school ranks are due out tomorrow, September 29. For those who don’t know, the last NRC ranking was in 1995 and the latest is much delayed (I.e. the “data” such as it is is already out of date.) Departments have been given access to the data for a week now but have been under embargo. As a blogger it is a moral imperative to search the inter tubes for leaks of this data. Surprisingly there has been little leaked, but today I’m proud to say that my own UW, while not technically breaking the embargo (okay maybe they have :)) has some info out about their forthcoming rankings. Now I’m probably definitely biased but I can pretty safely say that the UW CS ranking is off by a bit:

The NRC assessment of UW Computer Science & Engineering is based on clearly erroneous data. The assessment is meaningless, and in no way representative of the accomplishments of UW CSE. Errors in the data affect (at least) UW CSE, many other computer science programs nationally, and many programs in other fields at the University of Washington.
During the week of September 19th, NRC provided pre-release access to its long-delayed “Data-Based Assessment of Research-Doctorate Programs in the United States,” scheduled for public release during the week of September 26th.
We, along with colleagues in other computer science programs nationally and colleagues in programs in other fields at the University of Washington, quickly discovered significant flaws of three types in NRC’s data:

• Instances in which the data reported by NRC is demonstrably incorrect, sometimes by very substantial margins.
• Instances in which the accuracy of the data cannot easily be checked, but it does not pass even a rudimentary sanity check.
• Instances in which institutions interpreted NRC’s data reporting guidelines differently, yielding major inconsistencies.

Here are three specific examples affecting UW CSE:

• Due to difficulty in interpreting NRC’s instructions, NRC was provided with an incorrect faculty list for our program – essentially, a list that included anyone who had served as a member of a Ph.D. committee. In 2006 (the reporting year), UW CSE had roughly 40 faculty members by any reasonable definition. In the NRC study, our “total faculty” size is listed as 91 and our “allocated faculty size” (roughly, full time equivalent) as 62.5. A large number of these “additional faculty” were industrial colleagues – whose “academic records” (including grants, publications, and awards) were quantitatively evaluated by NRC as if these individuals were full members of our faculty. Since faculty size is the denominator in many measures computed by NRC, you can imagine the result – clearly erroneous.
• NRC reports UW CSE with 0% of graduate students “having academic plans” for 2001-05 (the reporting period for this measure). In fact, 40% of our graduating Ph.D. students took full-time faculty positions during this period. We are one of the top programs nationally in producing faculty members for major departments; in recent years our graduates have taken faculty positions at Berkeley, CMU, MIT, Princeton, Cornell, Wisconsin, Illinois, Michigan, Penn, Waterloo, Toronto, WashU, UCSD, Northwestern, UCLA, UBC, Maryland, Georgia Tech, UMass-Amherst, and many other outstanding programs. NRC obtained this number from an outside data provider; it’s clearly erroneous.
• NRC reports UW CSE as having 0.09 “awards per allocated faculty member.” The erroneous faculty count is not sufficient to explain this, given that our faculty includes 14 ACM Fellows, 10 IEEE Fellows, 3 AAAI Fellows, 14 Sloan Research Fellowship recipients, a MacArthur Award winner, two NAE members, 27 NSF CAREER Award winners, etc. We don’t know where NRC obtained this data, but it’s clearly erroneous.
  The University of Washington reported these issues to NRC when the pre-release data was made available, and asked NRC to make corrections prior to public release. NRC declined to do so. We and others have detected and reported many other anomalies and inaccuracies in the data during the pre-release week.

The widespread availability of the badly flawed pre-release data within the academic community, and NRC’s apparent resolve to move forward with the public release of this badly flawed data, have caused us and others to take action – hence this statement. Garbage In, Garbage Out – this assessment is based on clearly erroneous data. For our program – and surely for many others – the results are meaningless.
