The purpose of this study was to evaluate the effects of workshops and coaching on paraprofessional implementation of function-based interventions. The results of indirect and direct functional behavior assessment guided the development of intervention strategies for three students with autism and intellectual disability. Following intervention, students’ appropriate behavior increased and challenging behavior decreased. In general, paraprofessionals implemented strategies with high levels of fidelity and judged both the coaching and workshop training procedures and student intervention strategies as socially valid. Implications for practice, limitations, and suggestions for future research are discussed.
