The study took place in all 28 institutions of the Florida College System.

Study sample

A total of 11,300 first-time-in-college students in Florida were included in the study. Specifically, the data are from the 2012 and 2013 entering cohorts in all 28 institutions of the Florida College System. The sample consists of students who were eligible for the Florida developmental education program according to eligibility requirements as they existed in 2014 and later. In particular, students must have met at least one of three eligibility criteria to be included in the analysis: (1) not have a transcript record from a Florida public high school, (2) not have completed a standard high school diploma, or (3) have a standard high school diploma prior to 2006-2007. The study excluded students who did not have placement scores on the Postsecondary Education Readiness Test (PERT) or had incomplete high school administrative records. Sample characteristics were not available for the analytic sample. Among all non-exempt students across four student cohorts, 53% were female. Forty-one percent were White, 20% were Black, and 39% did not report race. Thirty-two percent were Hispanic or Latino, and the rest did not report ethnicity.

Intervention Group

This study examines Florida's developmental math education program, which required entering college students to take developmental math courses if they scored below college-ready in a placement exam. This review focuses on the findings for the pre-reform version of the program that was in place until 2014. The pre-reform version of the program assigned students to take either lower- or upper- developmental education courses for one semester depending on one's placement score. The lower-level course is the first course in a college-preparatory two-course sequence highlighting basic operations with applications to beginning algebra. The upper-level course is the second course in the college preparatory sequence which provides background on topics including basic operations with polynomials, linear equalities, factoring, and an introduction to radicals. Students assigned to the intervention were required to take these development courses before they could take college-level math courses. The outcomes were measured after students' first year in college. The manuscript also includes findings that measure the impact of the post-reform version of the program, and another set of findings that compare the post-reform version of the program to the pre-reform version. The WWC examined these findings and reported its conclusions in two other separate reviews of this manuscript. The WWC reviewed them separately because they focus on measuring the impact of a different intervention or use a different study design and analysis method.

Comparison Group

The comparison condition differed for the two levels of the developmental education intervention: (1) students assigned to upper-developmental education courses were compared to students who were placed into the business-as-usual college-level curriculum without developmental education courses, and (2) students assigned to lower-developmental education courses were compared to students who were assigned to upper-developmental education courses.

Support for implementation

The study does not describe any support for implementation for the pre-reform version of the program.
