The Evidence on Corequisite Support: How Bypassing Remedial Classes is Doubling College Pass Rates

For decades, higher education relied on a seemingly logical system for underprepared students: before they could take college-level math or English, they had to pass non-credit remedial courses.[1][2]

The theory was that these prerequisite classes would build foundational skills and prepare students for the rigors of a university curriculum. The reality, however, was a systemic failure often referred to by researchers as the 'remedial trap.'[2][3]

National data revealed that the vast majority of students placed into traditional remediation never earned a degree. Unable to access courses that awarded academic credit, many ran out of time, financial aid, or patience, and stopped out of college entirely before ever taking a class that counted toward graduation.[2]

In response to this attrition crisis, a massive structural shift is sweeping through community colleges and state university systems nationwide: the elimination of prerequisite remediation in favor of a model known as 'corequisite support.'[3]

Under the corequisite model, students who would have previously been deemed academically unprepared are placed directly into credit-bearing gateway courses—such as Statistics, College Algebra, or English 101—from their very first semester on campus.[2]

To bridge the academic gap, these students are required to take a concurrent support course. This often takes the form of a companion lab, extended instructional time, or mandatory just-in-time tutoring that aligns directly with the week's college-level syllabus.[1]

The evidence supporting this structural reform is some of the most robust in modern higher education research, demonstrating dramatic increases in gateway course completion across diverse student populations.[1]

When the Tennessee Board of Regents became the first state system to mandate corequisite implementation across all 13 of its community colleges, the results were unprecedented. System-wide math completion rates jumped from 12 percent under the old model to 61 percent, while English completion rose from 31 percent to 64 percent.[1][2]

Similar gains are materializing in California. After state legislation required community colleges to place students directly into transfer-level classes with corequisite support, the number of students completing transfer-level math in their first term more than doubled to 62,000.

Researchers attribute these massive gains not just to the extra tutoring, but to the elimination of structural attrition points. In the traditional multi-semester sequence, many students successfully passed their remedial class but simply failed to enroll in the subsequent college-level course due to life circumstances or financial strain.[1][2]

Corequisite models bypass this attrition entirely by mainstreaming students immediately. By taking the credit-bearing course and the support lab simultaneously, students save tuition money and accelerate their time to degree.[3]

The reform is also proving to be a powerful engine for equity. Because standardized placement tests have historically disproportionately placed Black and Latine students into non-credit remediation, those populations suffered the highest attrition rates under the old system.[2]

With the introduction of corequisite support, California reported that Latine and Black students are now completing college math courses at rates three to four times higher than they did under the previous prerequisite system.

However, while the evidence for short-term gateway course completion is overwhelmingly positive, the data on long-term degree attainment remains mixed, introducing a layer of transparent uncertainty into the policy debate.[1][3]

A randomized controlled trial conducted at the City University of New York (CUNY) found that assignment to corequisite math remediation increased the probability of a student graduating within three years by a modest but significant 5 percentage points.

Conversely, a comprehensive study by the Community College Research Center (CCRC) analyzing the Tennessee system-wide rollout found no significant impacts on overall enrollment persistence, transfer to four-year colleges, or degree completion.[1]

This suggests that while corequisite reforms are highly effective at helping students clear the initial hurdle of freshman math and English, they are not a silver bullet. Students still face financial, personal, and academic barriers later in their college careers that require broader institutional support.[1][3]

Furthermore, the transition has not been without friction among frontline faculty, particularly in STEM disciplines. Mainstreaming students with lower academic preparedness into rigorous courses like pre-calculus requires significant pedagogical adjustments.

Some instructors caution that while overall throughput has increased, the average grades in college-level math courses have occasionally declined for students below the traditional college-readiness threshold, raising concerns about maintaining academic rigor.

Despite these implementation challenges, the consensus among higher education researchers is clear: traditional prerequisite remediation is a failed model, and corequisite support offers a vastly superior, evidence-backed pathway to keeping students on track.[2][3]
