The 90/10 Rule in higher education requires for-profit colleges to get at least 10% of their revenue from non-federal sources, with a maximum of 90% from federal aid (like Title IV funds and recently, military benefits) to ensure they aren't solely reliant on taxpayer money and offer real value. Failing this rule for two consecutive years results in losing access to federal student aid, a penalty designed to protect students from low-quality, predatory institutions. Recent changes have closed loopholes by including GI Bill and military assistance in the 90% calculation, forcing for-profits to diversify funding.
