Robert Morse (Chief Data Strategist, U.S. News) & Eric Brooks (Principal Data Analyst, U.S. News), U.S. News Unranks Columbia University in 2022 Best Colleges Rankings:
U.S. News & World Report has unranked Columbia University from a number of rankings in the 2022 edition of Best Colleges (first published September 2021) after Columbia failed to respond to multiple U.S. News requests that the university substantiate certain data it previously submitted to U.S. News.
After learning about questions relating to Columbia’s submission, U.S. News Chief Data Strategist Robert Morse first contacted Columbia in March 2022 requesting Columbia substantiate data reported in its 2021 U.S. News statistical surveys on its counts of instructional full-time and part-time faculty, count of full-time faculty with a terminal degree, student-faculty ratio, undergraduate class size data, and educational expenditures data for the 2022 Best Colleges rankings. To date, Columbia has been unable to provide satisfactory responses to the information U.S. News requested. Therefore, today U.S. News moved the university to being "Unranked" in National Universities, meaning it no longer has a numerical rank in the 2022 National Universities, 2022 Best Value Schools, and 2022 Top Performers on Social Mobility because those rankings used data from the university’s statistical surveys.
Robert Morse, U.S. News Rankings Updates: Find Out About the  Schools That Misreported Data to U.S. News:
A very small proportion of the total number of schools that are ranked – typically less than 0.1% each year – inform U.S. News that they have misreported data that were used to calculate their school's ranking.
In these rare cases, the misreporting by these schools resulted in their numerical ranks being higher than they otherwise would have been if the correct data had been used originally. Because of the discrepancies, U.S. News moved the schools to the "unranked" category, meaning they do not receive numerical ranks.
Below are brief explanations pertaining to each school's data misreporting issue [in the 2019-2022 rankings] ...
