An external review of the conclusions regarding the peak direct training module
1St. Cloud State University.
Abstract:
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.
