Following up on a previous impact and cost study of the Dana Center Mathematics Pathways (DCMP) model, which used an individual-level randomized controlled trial, this study assesses the costs and cost-effectiveness of the program on longer-term college progress and college attainment. The version of DCMP included in this study diversified the developmental and college-level math course content, separating the content into distinct pathways that better aligned with students' career interests. It also streamlined the developmental math sequence into a one-semester developmental course for all students, regardless of placement level, and implemented an evidence-based curricula and pedagogy to engage students in active problem solving pertinent to real-life situations. The study, which included 1,411 students across four Texas community colleges and ten campuses, found that DCMP saves students money and may be cost-effective when used as part of a larger strategy to improve student success.
