According to a Chronicle analysis of data released on Tuesday, 177 private colleges that grant degrees failed a U.S. Education Department test for financial responsibility in the 2014-15 academic year. That’s 18 more than the previous year. Of the institutions that failed, 112 are nonprofit, and the remaining 65 are for-profit. In the previous year, 93 of the 159 failing institutions were nonprofit. The department considers an institution’s debt and assets, among other factors, in giving it a score ranging from -1 to 3. Scores lower than 1.5 are considered failing. The department’s methodology in devising the scores has drawn sharp criticism in the past from some higher-education groups. The latest scores cover the institutions for fiscal years ending between July 1, 2014, and June 30, 2015. Several of the colleges have closed since the 2014-15 academic year. Some, like Dowling College, in Oakdale, N.Y., previously failed the financial-responsibility test, while others, like Saint Joseph’s College, in Rensselaer, Ind., passed it.
