New research from Rize Education challenges a core strategy at many small residential colleges: shifting emphasis to “non-traditional” revenue streams like online programs, microcredentials, and adult learner markets. The report argues that those bets often fail to stabilize the undergraduate “core,” while increasing volatility. The study, The Subsidy Trap: Why Non-Traditional Revenue Rarely Fixes the Core, points to enrollment declines among adults that appear structural rather than temporary—citing National Student Clearinghouse Research Center data showing adult enrollment at private four-year institutions fell 28% year-over-year in Fall 2025. It also highlights declines in new undergraduate students over 25 and a decade-long contraction in adult enrollment across four-year institutions using IPEDS. On the fully online side, Rize finds that after many institutions expanded online offerings between 2020 and 2022, online participation rates declined from 59% of students in fall 2021 to 53% by 2022–23. The report adds that primarily online institutions saw a 1.6% enrollment decline in Fall 2025, reversing prior growth patterns. Graduate programs—often treated as the flagship non-traditional revenue solution—are also flagged as structurally vulnerable. The research’s bottom line: institutions relying on these revenue substitutions may be misreading where competitive dynamics and demand are weakening.
