This study evaluated the effects of manualized training in "Basic" functional behavioral assessment (FBA) for typical school professionals on the ability of these professionals to complete technically adequate FBAs. Twelve school professionals participated in four 1-hr training sessions using the Basic FBA training handbook. After documenting knowledge competencies, 10 of the 12 professionals each completed a formal FBA with a student from their school. The technical adequacy of these 10 FBAs was assessed with functional analyses. Results from the 10 functional analyses confirmed that all 10 school professionals accurately identified the antecedents and consequences controlling student problem behavior. The efficiency and social validity of the Basic FBA training process was also investigated. These preliminary findings suggest a role for behavior specialists to train typical school personnel in Basic FBA procedures. Implications, limitations, and directions for future research are presented.
