Pursuant to statute (23-1-113 [9] C.R.S), the Colorado Department of Higher Education (CDHE) is required to submit a report concerning the postsecondary academic progress and success of the preceding six high school graduating classes. Due to limitations on the availability of data, this report covers the high school graduating classes of 2009, 2010, 2011 and 2012. This report has been submitted to the Education Committees of the Senate and House of Representatives and to the State Board of Education. This report, the third of its kind, consists of four parts: (1) Postsecondary enrollment trends, including information on in-state and out-of state enrollment and institution type, disaggregated by ethnicity and gender; (2) Information on first-year college students in Colorado, including financial aid status, average grade point average, credit accumulation and degree level, disaggregated by ethnicity and gender; (3) First year retention rates; and (4) Information on postsecondary credential attainment. This report is intended to summarize and identify trends in postsecondary education for four cohorts of Colorado high school graduates, with particular attention paid to the most recent cohort. The report describes student enrollment and progress one year following graduation. The data are disaggregated by gender and race/ethnicity to further identify patterns. New to this year's report is a section on credential attainment. Four years after high school graduation, nearly 30 percent of the 2009 graduates who immediately enrolled in a public, in-state college had earned some type of postsecondary credential, whether it be a certificate, associate degree or bachelor's degree. This information is an exciting addition to the report as it allows a further assessment of the postsecondary progress of Colorado's high school graduates identifies where in the educational pipeline Colorado is losing students. Appended are: (1) District-Level Statistics; and (2) Technical Information.
