The general objectives were to develop and implement computer-based procedures for obtaining validated data on the characteristics of vocational school students, and to convert this data into counseling information. To do this, two types of data information conversion procedures were used: discriminate analysis and regression analysis. Scores from 36 aptitude, interest, and personality measures were accumulated for approximately 1,600 prospective vocational high school students as well as a progress record for each of these students while attending the vocational high school. Multivariate analyses conducted on antecedent and criterion data formed the bases for data information conversion procedures used in the field tests involving 900 prospective students. Results of the study support the development of a generalized system of computer-based procedures for data information conversion as both feasible and desirable. Work was started on a generalized Test Validation and Information Feedback System which is scheduled to be operational by late 1970. Project activities will continue with local support. (Author)
