--- - |2 Promoting the Emergence of Advanced Knowledge—Direct Training Module (PEAK‐DTM) is a commercially available assessment and curriculum for individuals whose language skills are not developmentally adequate. In their review of PEAK‐DTM, Reed and Luiselli (2016) analyzed the extant literature on PEAK‐DTM and concluded that it has a sound and growing body of empirical support on its efficacy, usability, and psychometric properties. Similar conclusions are mirrored in the PEAK‐DTM literature and promotional material. I review these conclusions and contend that many overrate the research that backs them. Suggestions for a more rigorous research agenda on PEAK‐DTM and its related modules are provided. - Journal of Applied Behavior Analysis, Volume 51, Issue 3, Page 719-737, Summer 2018.
