This report presents the results of the Fall 2015 Developmental Education Report for the Maricopa County Community College District. Section 1 of the report provides numbers of students enrolled in one or more developmental courses in the Fall 2015 Term. Section 2 Deals with placement. The placement and performance sections of this report (Sections 2-4) were largely based on the Student Success Initiative (SSI) cohort, specifically students who were new to higher education and degree- or transfer-seeking. Section 3 deals with student performance and reveals that successful completion rates in developmental courses have been improving for the last five cohort terms, from 62% (Fall 2010) to 70% (Fall 2014). Highlights of key findings include: (1) Total enrollment in developmental classes (not limited to any cohorts) increased only slightly over last fall (0.7%). Fewer students enrolled in English and reading developmental classes, but 24% more students enrolled in math developmental courses; (2) A smaller percentage of students who were new to higher education and degree- or transfer-seeking tested into developmental education; 64% this past fall compared to 65% in 2014; (3) Recent high school graduates continued to test into developmental education at lower rates than students who had been out of high school for more than one year (with the exception of reading, which was the same as the prior fall); (4) Successful completion rates in developmental courses have improved over the past 5 years from 62% to 70%; and (5) Success rates in subsequent college-level courses remained stable for math and increased for English compared to last year's report.
