Private postsecondary education leaders are concerned with the value of education and the benefits students receive after graduation. Federal regulations dictate that private postsecondary education institutions will not qualify for Title IV funds if they do not meet minimum student outcome requirements, including cohort default rates and 90/10 rule ratios. Grounded in principal-agent theory, the purpose of this quantitative correlational study was to examine the predictive relationship between cohort default rates, 90/10 rule ratios, and gross revenue by institution size. Data were collected from publicly accessible repositories that provide data from U.S.-based postsecondary education institutions on 167 for-profit postsecondary Title IV institutions in California between 2016 and 2018. The results of the multiple linear regression analysis were not significant. A key recommendation from this study is for postsecondary education leaders to examine other potential factors that predict impacts on gross revenue. The implications for positive social change include the potential for higher education leaders to maintain federal Title IV funding, reduce poverty and crime, and reduce inequality.
