A study was conducted to assess the use of the Psychological Services Bureau's Aptitude Test for Practical Nursing (PSB Aptitude Test) as an entrance requirement for the licensed vocational nurse (LVN) program at College of the Sequoias. The study sought to determine whether the PSB Aptitude Test was a valid indicator of success in the LVN program, and if other requirements could be used instead. Data were obtained on 35 students who had been accepted in the LVN classes for fall 1980-81 and spring 1982-83 and a linear multiple correlation and regression analysis was used to compare the dependent variable, success in the LVN program as determined by student grade point average (GPA), with three independent variables: PSB scores, science GPA, and math-reading scores. The conclusions reached in the study were: (1) no significant association was found involving PSB scores as a predictor of nursing GPA; and (2) both science GPA and math-reading scores were significantly related to success in the LVN program. Based on results of the study, a revision of LVN admission policy was recommended, eliminating the PSB Aptitude Test as an entrance requirement for the LVN program and using science GPA and math-reading scores as predictors of student success in the program. Appendices provide the LVN interview point scoring system, study hypotheses, and raw data. (Author/HB)
