A study was conducted to develop a technical skills assessment tool for the training and development of challenge course facilitators. Researchers accessed two professional on-line listserves to collect a sample size of twenty-seven currently used technical skills assessment tools. The assessment tools were critically analysed by three independent reviewers. As a result, ten commonly assessed technical skills were identified. A rubric was then developed based on the ten technical skills. A Delphi panel consisting of seven challenge course professionals completed a total of four reviews and revisions of the rubric resulting in the Challenge Course Facilitator Technical Skills Assessment Tool.
