Inquiry Group participation for PDS teachers and teacher candidates is one of the signature programs of the Bowie State University PDS Network and provides PDS teachers and teacher candidates the opportunity to collaborate on teaching strategies and methodologies to use in their classrooms. This article uses self-study methodology to explore the process for developing and implementing inquiry groups and suggests a research-based guide for implementing inquiry groups in a PDS setting. It also describes the experiences of PDS teachers and teacher candidates as they participate in site-based inquiry groups and provides insight into the impact of inquiry groups on the partnerships. Inquiry groups are also explored as a developmentally appropriate form of teacher research for PDS teachers and teacher candidates to use before they engage in more formal collaborative action research. This article provides a rationale for the use of self-study research methodology to investigate PDS partnerships.
