A study was conducted to evaluate the effectiveness of the Tests of Adult Basic Education (TABE) in predicting success or lack of success in selected postsecondary health occupations programs. The predictor variables used in the project were the TABE reading and mathematics grade equivalent scores and the number of times each section of the TABE was taken. Criterion variables were (1) successful completion of a health program or withdrawal and (2) scores from the Kentucky Vocational Achievement Test (KVAT). The project sample included all students in Kentucky admitted to the following postsecondary health occupations programs who had taken the TABE for admission: practical nurse, dental assistant, surgical technology, respiratory therapy, radiologic technology, and medical assistant. The total population for the research was 1,485. Pearson product-moment correlation coefficients and true stepwise multiple regression analysis were used to test the correlation using .05 level of significance. Data analysis by program was conducted on sets of variables with complete data. The sample size for each analysis was reported. The TABE reading and mathematics grade equivalent scores and number of attempts were not good predictors of program completion or withdrawal. Discriminant analysis failed to classify completion or withdrawal correctly from any of the health programs. (Author/KC)
