Some 37.6 million working-age adults had some college credits but no credential at the start of the 2023-24 academic year, according to new data released Wednesday by the National Student Clearinghouse Research Center. The population, up 2.2% nationally from the previous year, increased across all states. But reenrollment among “some college, no credential” adults climbed by 2.7%, marking the second annual increase in a row. The 2023-24 academic year also marked the first time more than 1 million stopped-out students reenrolled in a single academic year. A majority of states and the District of Columbia saw the uptick, ranging from a 0.7% increase in Washington, D.C., to a 35.2% jump in Massachusetts, the clearinghouse said.
