The purpose of this study was to examine the effectiveness of one consultation course on the development of pre-service school psychologists' consultation knowledge, confidence, and skills. Computer-simulation was used as a means to replicate the school environment and capture consultants' engagement throughout the consultation process without many common real-world constraints (e.g., time, teacher resistance). Ten school psychology graduate students completed one simulated case at the beginning of their first consultation course and another case upon completion of the class; therefore, a one-group pre- post-test design was utilized to examine their development. Results indicated that novice consultants grew across all three areas of competence evaluated in the study (knowledge, confidence, and skills). That being said, the growth in confidence was incommensurately large as compared to knowledge and skills, with skills remaining the least developed upon completion of the consultation course. Implications for training are discussed.
