In this exploratory study of 95 counseling program master's students at a large southwestern public university, students' scores on an admissions Group Interview Sociometric Rating did not correlate with their GRE Analytic Writing (GRE-AW) scores nor their basic skills course instructors' end-of-course assessment of students' counseling-related personality traits (Personality) or mastery of basic counseling skills (Mastery). However, Mastery was predicted by both Personality, with a large effect size, and GRE-AW, with a medium effect size. This study provides promising preliminary evidence that counselor educators may use Counselor Personality Assessment Ratings and GRE-AW scores to screen master's applicants by predicting students' abilities to master basic counseling skills early in their counselor preparation. Limitations of the study and recommendations for future research are discussed.
