The College Course Map (CCM) is a taxonomy system for coding postsecondary education courses in NCES research studies. Originally developed in 1988 in support of the postsecondary transcript study in the National Longitudinal Study of the High School Class of 1972 (NLS-72), the taxonomy was updated in 1993 for the High School and Beyond Study (HS&B) and again in 2000 for the National Educational Longitudinal Study (NELS:88/00) (Adelman, 2005). The 2010 College Course Map (CCM:2010) was updated in 2009 in support of two postsecondary education transcript collections. The 2009 Postsecondary Education Transcript Study (PETS:09) incorporated transcript collections for the 2004/09 Beginning Postsecondary Education Students Longitudinal Study (BPS:04/09) and the 2008/09 Baccalaureate and Beyond Study (B&B:08/09). This publication describes how the newest version of the College Course Map was updated and provides a listing of all the course codes used for PETS:09. (Contains 2 figures and 1 footnote.)
