Developmental Education programs are designed to provide assistance to students who are academically under-prepared for college-level coursework. Previous issues of "Data Notes" compared the outcomes of developmental students completing all of their required developmental courses to those not requiring developmental education. Using data from Achieving the Dream: Community College Count, this analysis examines outcomes of four different groups of students organized by their developmental needs and completion statuses: students referred to developmental education and completing (1) all, (2) part, (3) none of their developmental education requirements during the first academic year and (4) those not referred. The results suggest that getting students who need remediation to enroll in the appropriate classes immediately, and doing everything possible to help them succeed will result in improved completion rates. The results also show that different measures of student success - persistence, credits completed, and GPA - can provide conflicting evidence. (Contains 3 figures and 9 footnotes.)
