Private or Parochial School - Appendix 1

National Longitudinal Survey of Youth - 1997 Cohort

Private or Parochial School - Appendix 1

This variable was last created in round 13.

Variable Created

  • CV_SCHOOL_TYPE (SLTYPE)

This program is used to create the school type variables, i.e. to indicate whether the current or most recent schools that the youth attended are public (code 1), private (2), parochial (3) or other (4). This is completed in the following steps:

  1. We first decide which school is the most recent school (non-college) that the youth participated by the ending date for different enrollment periods.
  2. We can get the school type from the new school roster. However, in the program, these two steps cannot be separated.
