A battery of tests, designed expressly for use in assessment of disadvantaged adolescents enrolled in youth-work training programs, was validated predictively against both short-term (program completion) and longer-term (post-program) behavioral outcome dimensions. Measures of the battery displayed their best validities with such longer-term criterion dimensions as Social and Vocational Adjustment, Job Success and Satisfaction and Job Search Motivation. The most valid tests were three Practical Reasoning measures (i.e., skill at following directions in job tasks); three Vocational Orientation measures (i.e., knowledge of job requirements and skill at seeking and holding jobs) and two attitudinal measures (Self-Esteem and Attitude Toward Authority). The most relevant short-term criteria were also identified and future potential of the test battery for programmatic evaluation and guidance applications was discussed. (Author)
