A research study examined the extent and impact of one-year enrollments by 12th graders in 2-year secondary vocational programs in New Hampshire. Enrollment data from 1981-1982 and 1982-1983 school years from six rural Regional Centers were used for the sample. A review of current literature found that no other state has ever researched the prevalence of 12th graders in first-year vocational programming. Personal interviews with vocational directors, principals, guidance personnel, and teachers and a mail survey of 12th graders provided the necessary data. A sampling of responses revealed that vocational education is considered an elective at all selected sites. Class enrollment has a greater influence over composition than the concept of 2-year sequential enrollment. Guidance personnel and several vocational directors did encourage 12th graders to enroll for career exploration. Most vocational directors, principals, guidance personnel, and students believed that necessary competencies for entry-level employment could be taught and learned in the first year.
