Cooley Law School (Cooley) is a private law school in Lansing, Michigan, and Riverview, Florida. It was established in 1972. At its peak in 2010, Cooley had over 3,900 students and was the largest US law school by enrollment; as of October 2024, Cooley had 420 students between its two campuses. In November 2020, Western Michigan University's board of trustees voted to end its affiliation with Cooley, which began in 2014, with disassociation effective November 5, 2023. Beginning in 2020, Cooley has failed to reach the 75% two–year bar passage required of ABA Standard 316 for continued accreditation and, effective 2025, was placed on probation by the ABA due to noncompliance with the required minimum two-year bar passage rate. Multiple media outlets have labeled Cooley the "worst law school in America".
