New research from the Brookings Institution questions the effectiveness of corequisite math support—where underprepared students enroll in college-level math alongside additional help. In English, corequisite support improved first-year pass rates by about five percentage points compared with similar students who did not receive remedial support. But in math, the analysis found no significant impact from either corequisite or prerequisite models. The report suggests that corequisites may still be outperforming prerequisites mainly by steering students toward completing gateway math coursework through pathways other than standard college algebra. The findings raise a practical issue for institutions planning placement and support strategies for underprepared students, with implications for student progression, funding, and course design.
