Vocational Evaluator Competencies and Minimum Competency Standards for Vocational Evaluation: A Validity Study.
Sigmon, Gary L.; And Others
In recent years educators have been utilizing judgmental methods, such as the ones advocated by Ebel and Angoff, to set minimum competency standards on test items. This study was designed to investigate the reliability and validity of these two procedures in setting minimum levels of performance on 175 vocational evaluator competency statements. Each of 24 vocational evaluation rehabilitation educators and 19 vocational evaluation field personnel rated each of the 175 statements, utilizing first the Ebel (1972) procedure followed by the Angoff (1971) rating procedure. The reliability and validity findings demonstrate that the Ebel and Angoff methods may be utilized in a valid and reliable manner to establish minimum levels of performance at the competency level. The Ebel method was most reliable. These results may give new insights to decision makers who prefer to answer the question of how many competencies a candidate must master over the more traditional question of how many test items a candidate must answer correctly.
