The number of first-year students at the University of California, San Diego, whose math skills fall below a middle school level has increased nearly 30-fold over the past five years, according to a new report from the university’s Senate–Administration Working Group on Admissions. In the 2025 fall cohort, one in eight students placed into math below a middle school level, despite having a solid math GPA.

For fall 2024, UC San Diego revamped its remedial math course to address middle school math gaps and introduced an additional remedial course to cover high school math. In fall 2025, 921 students enrolled in one of these two courses—11.8 percent of the incoming class.
