This applied dissertation evaluated a new method that provided a systematic way of training and evaluating supervisors in Applied Behavior Analysis (ABA). Using a single-case multiple- baseline across supervisors and supervisees research design, this study assessed the use of a modified behavioral skills protocol (BST) in the training of master’s and doctoral-level Board Certified Behavior Analysts (BCBAs/BCBA-Ds) in the supervision of DTT. Additionally, this study evaluated supervisee’s performances before and during the implementation of the modified BST protocol. Included in the new supervisor training curriculum outline (2.0) released by the BACB in 2019, BST is an evidence-based protocol whose efficacy has been primarily established in the area of staff training. Results revealed that the use of the new modified BST protocol for the training of BCBAs on the supervision of DTT had a positive effect on supervisors’ and supervisees’ performances, when compared to baseline values.
