URBANA — An assistant law school dean has resigned in the wake of a university investigation into the posting of inaccurate class data at the University of Illinois College of Law.

The UI on Monday announced it concluded its investigation into inaccuracies found with the law school's student profile data and issued a final report Monday. That report uncovered intentional inaccuracies in six of the 10 years reviewed, and a single individual was solely responsible for these inaccuracies. The report also found the College of Law lacked adequate controls to prevent, deter and detect such actions, according to a university release.

Paul Pless, the college's former assistant dean for admissions and financial aid, "knowingly and intentionally" miscalculated key data, according to the university. The admissions dean was placed on administrative leave Sept. 7 and resigned from the university last week.

The UI disclosed the matter to the public on Sept. 9 and released corrected profile data for the class of 2014 and the classes of 2011, 2012, and 2013. The investigative team consisted of the law firm Jones Day, directed by Theodore Chung, and data analysis firm Duff & Phelps, directed by Margaret Daley. The report was prepared by Jones Day and Duff & Phelps under the direction of Donna McNeely, the UI's ethics officer, and Scott Rice, chief legal counsel for the university's Urbana-Champaign campus.

For seven years, Pless was responsible for reporting key law school data and during that time the college showed steady, and occasionally dramatic, improvement in the main factors used to gauge the academic credentials of a law school class, according to the UI. The data discrepancies were not random or the result of inadvertent errors, the investigation found.

"Numbers were altered specifically, and often just slightly, to meet recruitment goals and ranking targets indicating an attempt to demonstrate that the College of Law brought in an even more highly credentialed class," said Margaret Daley of Duff & Phelps, in a UI news release.

The investigation found no information indicating that, prior to the beginning of the investigation, any person other than Pless knew erroneous profile data had been reported or disseminated by the college, according to the UI.

Law Dean Bruce Smith issued an apology to the legal-academic community, the university, alumni and students.

"The investigation has concluded that a single individual — no longer employed by the college — was responsible for these inaccuracies. The college takes seriously the issue of data integrity and intends to implement the report's recommendations promptly and comprehensively," he said in the release.
