Columbia University provost Mary Boyce announced Thursday that the university would not submit any data for the next rankings of U.S. News & World Report.

“A few months ago, a member of our faculty, Professor Michael Thaddeus, raised questions regarding the accuracy of some of the data the university submitted … for its annual ranking of undergraduate universities. Columbia leaders take these questions seriously, and we immediately embarked on a review of our data collection and submissions process,” said Boyce. “In light of the work underway, we will refrain from submitting to U.S. News and World Report this year. The deadline for that submission is July 1. Given the extensive analysis required to review the data and ensure it complies with U.S. News methodologies, we cannot complete our work with the appropriate care within that timeframe.”

She added, “Columbia has long conducted what we believed to be a thorough process for gathering and reporting institutional data, but we are now closely reviewing our processes in light of the questions raised. The ongoing review is a matter of integrity. We will take no shortcuts in getting it right.”
