Action research is a method of organizational development and improvement often used in educational settings. This study implemented an action research process in an alternative school that serves students with significant special needs. The action research process was implemented by classroom teams who developed a research question, collected and analyzed data, and made decisions about how to improve their current practices based on the data. The action research training project consisted of three stages: training in the protocol of action research, follow-up coaching and on-site assistance to participants, and a follow-up study. There were eleven instructional teams, made up of teachers, paraprofessionals, and therapists that took part in the training. One year after the initial training, one-on-one interviews were conducted with sixteen participants for the follow-up study. Eleven people reported that they were continuing to use action research in their classrooms and five people reported they were not. Teacher leadership to implement the process, viewing action research as part of their daily job duties, valuing the collaborative aspect of the process, and valuing the opportunity to serve students better contributed to continued use of action research. Staff turnover, lack of time, and lack of motivation contributed to discontinued use.
