Through professional development schools (PDSs), the College of Education at Texas Tech University has attempted to link school and teacher education renewal with research. In 1990, the university and Lubbock Independent School District initiated PDSs at a junior high school and an elementary school. Three additional PDS sites have been initiated since then, including a rural K-12 school. In addition to discussing steps involved in initiating the professional development school collaborative, this paper describes several specific PDS initiatives. Considerable emphasis has been placed on staff development, which focuses on building the capacity of university- and school-based faculty for educational renewal. Each partner in the collaborative actively participates in planning research and inquiry designed to test ideas, practices, and innovations. At each PDS, a functioning cadre exists to promote the reflective practice, inquiry, and research that are seen as central functions of the PDS. Both process and outcomes data are being collected from individual PDSs, and a description of collection procedures and a list of the research studies underway are included. The university's PDS-related research efforts are linked to other collaboratives: West Texas State University, Wayland Baptist University, Lubbock Christian University, two regional service centers, and multiple school districts in the Panhandle-south Plains of Texas.
