Reid et al. ( 2025) recently published the third edition of The Supervisor’s Guidebook: Evidence-Based Strategies for Promoting Work Quality and Enjoyment among Human Service Staff. Supervisors can use this guidebook as a tool to shape their own practices to ensure they are adhering to an evidence-based supervision protocol, while encouraging staff acceptability and workplace enjoyment. The purpose of this review is to evaluate the recommendations made by Reid et al., highlight key themes of the book, discuss the limited changes made in the current edition and suggested readings, identify limitations, and highlight some areas for continued development in future editions. When reviewing the current edition of The Supervisor’s Guidebook: Evidence-Based Strategies for Promoting Work Quality and Enjoyment among Human Service Staff, written by Reid et al. (2025), much of the information and strategies provided remained consistent with the previous edition, with a strong emphasis on how to deliver quality, evidence-based supervision. As such, we describe the key themes of the book, review the limited changes made in the current edition and suggested readings, identify limitations, and highlight some areas for continued development in future editions. Throughout this article, we will refer to Bartle et al. (2024), who published a review of the second edition of this guidebook, as a resource. We recommend Bartle et al. (2024) for a detailed overview of the book’s chapters and content not discussed here. The intended audience for this work is board certified behavior analysts (BCBA), or practitioners that are in similar supervisory roles, leading direct-support staff in behavior-analytic services.
