Classification of Instructional Programs (CIP) is a taxonomy of academic disciplines at institutions of higher education in the United States.
The CIP was originally developed by the National Center for Education Statistics (NCES) of the United States Department of Education in 1980 and was revised in 1985 and 1990. The 2000 edition (CIP-2000) is the third and current revision of the taxonomy. Instructional programs are classified by a six-digit CIP at the most granular level and are classified according to the two-digit and four-digit prefixes of the code. For example, "Forensic Science and Technology" has the six-digit code 430106, which places it in Criminal Justice and Corrections (4301) and "Security and Protective Services" (two-digit CIP 43).
