The purpose of this study was to apply two of Kirkpatrick's Four Levels of Training Evaluation to evaluate the implementation of PAX Good Behavior Game training in a challenged Ohio middle school. The study explored teacher "reactions" to and perceived "learning" from the training as it relates to the middle school's goals, and recommended "changes" to make the training more middle school focused. Data were collected via survey and semi-structured interviews of the trainees. Findings suggest a majority of the trainees perceived the training as useful to the goal of building relationships, but not the goals of creating student incentives, implementing the PBIS Framework or decreasing chronic absenteeism. A majority of trainees perceived the training was not "relevant" in their particular role but was "effective" in preparing them to implement the PAX GBG to address specific identified gaps affecting the school's report card, with varying perceptions on specific kernels. Qualitative data from open-ended questions and five participant interviews suggest trainees wanted more concrete examples and modifications to make it more middle school focused. Findings are consistent with Kirkpatrick and Kirkpatrick's (2016) recommendations to include participants in the planning phase to ensure "usefulness," to tie training to specific roles to ensure "relevance" for all participants, and to collect formative feedback to ensure the "effectiveness" of the training. Limitations of this study are discussed, as well as recommendations for future research to determine if results can be generalized, and extend evaluation of the PAX GBG training beyond reactions and subjective learning, to assess objective learning, behavior change and results.
