These are the appendixes for the full report, "Exploring Implementation of Trauma-Engaged Practices in Alaska Schools." The report was developed to provide a better understanding of implementation of trauma-engaged practices in Alaska's schools. Using existing administrative and survey data gathered by the Alaska Department of Education and Early Development, this study found that Alaska schools' implementation of trauma-engaged practices varies, with most schools demonstrating an emerging level of implementation (the middle level of implementation relative to all study schools). The appendixes included in this document are: (1) Data, sample, and methods; (2) Supporting analyses; (3) Interview protocols and codebooks; and (4) Trauma-Engaged Practices and Policies Implementation Survey.
