The competency-based movement in psychology has significant implications for how psychologists are trained and evaluated. For this reason, there is a growing need to examine how to develop and evaluate competence to ensure that psychologists are prepared for practice. One area in need of more attention is consultation. Consultation is a functional competence for all psychologists, and it is also a foundational competence for school psychologists. Therefore, the purpose of this study was to assess how competently school-based consultants implement consultation in a computer-simulated school setting. A qualitative case study design was used to evaluate the competence of four graduate students in school psychology. The results of the study indicate that although consultants had high consultation knowledge and confidence, there were weaknesses in their demonstrated skills. Implications for competency-based training as well as using computer simulation for competency-based assessment are discussed.
