Career Planning Validity of Self-Estimates and Test Estimates of Work-Relevant Abilities‪.‬

This study sought to determine whether self-estimates of work-relevant abilities can improve upon the validity of test estimates (scores). Validity for career planning applications was the focus. The study (final sample of 1,620 college students) used 9 self-estimates and test estimates to predict certainty-screened occupational choices grouped by J. L. Holland (1997) types. The addition of ability self-estimates to test estimates substantially improved upon the validity of test estimates alone. Study results (together with previous research) suggest that ability self-estimates can provide efficient additions or alternatives to test estimates during career planning, while substantially broadening the range of abilities under consideration. **********
