The final report describes a Texas study to determine if differences in occupational achievement existed between those high school graduates who had been enrolled in vocational education programs and those who had not. A questionnaire was sent to 3,045 individuals who graduated from high school in 1970 in Austin, San Antonio, and Houston, to determine their occupational achievement. Statistics were based upon the 894 questionnaires returned, with six variables of income and length of employment used: accumulated income, monthly earnings, hourly rate, weekly working hours, employed months, and actual job length. Analysis of variance and multiple regression analysis were the statistical techniques used. A summary is provided and chapters include: (1) study background information; (2) descriptions of research methods and techniques; (3) discussion of test factor associations; (4) presentation of preliminary analysis findings; (5) presentation of further testing; (6) discussion of conclusions and policy implications. Thirty-one tables supplement the text. Appended material includes additional tables, the questionnaire and accompanying letters, and extensive coded raw data on the 894 participants. It is stated that vocational education has proved effective as pre-employment training for those graduates who made a direct transition from school to work. (LH)
