From the abstract: "While there are multiple evidence-based practices (EBPs) available for students with autism, ongoing barriers to use in schools include limited access to training for educators and substantial provider modifications that limit fidelity. This suggests a need for further research to support data-informed adaptations and innovative methods for training and coaching teachers. In response to this need, the objectives of this protocol paper are to (1) describe the development of a data-informed adaptation process for an EBP, and (2) compare the effectiveness of two methods (online virtual and a combination of in-person and online virtual) for training teachers to use the adapted EBP. Outcome measures will include teacher implementation and sustainment of the EBP, teacher/coach relationship, and student outcome."
