However, over 943,000 stopped-out students reenrolled in 2022-23, according to the National Student Clearinghouse Research Center. Yet those improvements haven’t halted the growth of the stopped-out population. “Higher education regularly generates more students leaving school without a credential than returning to finish one,” Doug Shapiro, the research center’s executive director, said in a statement. The population of U.S. adults under age 65 with some college but no credential reached 36.8 million by July 2022, up 2.9% compared to the year before, according to a new analysis from the National Student Clearinghouse Research Center.
