This document summarizes a presentation on using reflective practice and the DATA model to enhance evaluator's professional activities. The DATA model provides a framework for reflective practice, with the steps being: (D) describe what is happening, (A) analyze why it is happening, (T) theorize based on the analysis, and (A) create an action plan for change. The presenters provide an example of how the DATA model can be applied in practice and discuss how reflective practice is an important competency for evaluators beyond just congratulating oneself after an evaluation.
