The purpose of this research study was to identify practices that principals utilize that are believed to influence teacher retention. Teacher turnover is a major problem facing principals and school systems today. Much of the present research focuses on why teachers leave the field, but there is little research on the principals' perceptions of what they do to stem the flow of educators leaving the classroom. To accomplish this purpose, a case study was conducted, focused on identifying the principals' role in teacher retention and their perceptions of the most important strategies utilized to stimulate high teacher retention. Qualitative research methods including individual interviews, open-ended questionnaires, and focus groups enabled the researcher to identify, compare, and contrast the perceptions, beliefs, and practices used by the nine study participants. The research design produced interviews filled with rich narratives describing the practices used by principals at schools with high teacher retention. The focus group discussion elucidated the common behaviors that were perceived to support teacher retention. The study yielded evidence that high-performing principals with high teacher retention rates clearly and consistently identified specific practices they believe support teacher retention; that principals play a vital role in teacher retention and that their leadership, support, and daily practices influence a teacher's decision to remain in teaching. The data collected indicates the centrality of creating a positive school culture and a sense of belonging. All the other identified principal practices are intertwined with and contribute to this outcome. / Choosing, supporting, and valuing faculty and encouraging shared decision-making appear to be the central practices in building teacher retention; and these practices are supported by and integrated with principals' modeling of positive personal characteristics, exercising fairness and equity, being visible and approachable, and communicating in an open two-way manner. Congruence of findings from all data collection methods provided an updated list of common practices identified by these highly successful principals that may inform principal preparation and a professional development model for present and future educational leaders interested in maintaining a stable teaching faculty. / by Janet A.
