A project examined the mathematics and science performance of vocational students in Ohio. Part I of the study achieved the first objective--to report the science and mathematics content contained within the Ohio Vocational Achievement Tests for the 38 program areas. Each of the 38 tests was presented and found to have sound psychometric properties. In general, each test contained reasonable numbers of science and mathematics items. Part II achieved the second and third objectives--to determine the level of functioning and the proportion of correctly answered questions by juniors and seniors enrolled in vocational education programs in the areas of science and mathematics in each program area. In general, seniors outperformed juniors in each program area; the level of performance was at a reasonable level. Performance across the 38 levels on both science and mathematics varied among the different vocational groups. Part III achieved the fourth objective--a pilot study to determine the feasibility of experimentally comparing students enrolled in vocational education programs with students enrolled in traditional education programs on common paper and pencil indicators of science and mathematics performance. Performance of students in three vocational education programs compared favorably with students in college preparatory and general academic programs. (YLB)
