Patterns and trends in the vocational-technical course taking of public high school graduates between 1982 and 1998 were examined in a study of high school transcripts for the graduating classes of 1982, 1990, 1992, 1994, and 1998. The source data came from the following five studies: (1) High School and Beyond Sophomore Cohort, First Follow-up Survey, (2) High School Transcripts Study, 1982; (3) National Education Longitudinal Study of 1988, Second Follow-up Survey; (4) High School Transcript Study, 1992; and (5) High School Transcript Studies of 1990, 1994, and 1998. The analysis revealed differences in participation in vocational-technical education based on the following variables: race/ethnicity; sex; disability status; English proficiency; academic achievement; and school urbanicity and poverty level. Generally, graduates took fewer vocational courses between 1982 and 1998, although their occupational course taking was relatively steady. Graduates with disabilities as of grade 12 took more vocational and occupational course work by the end of the period studied. Asians and Pacific Islanders and high academic achievers did not exhibit the declines in vocational course taking that were observed for other groups. (Fifty-four tables/figures are included.
