What considerations influence the variable specification and the codes to be used?
Some variables are unique to the CSP, but whenever possible we have used definitions and codes existing in other data collection projects. For example, a variable that specifies students majors is coded according to Classification for Instructional Programs (CIP) standard conventions (see http://nces.ed.gov/pubs2002/cip2000/ ); race/ethnicity is coded using Department of Education (DOE) standards.
