Teacher retention continues to be a challenge for school districts around the United States. This seems to be also the case for schools in Milwaukee, particularly those that are part of the Milwaukee Parental Choice Program (MPCP). The purpose of this quantitative study was to identify the factors that impact teacher retention rates in Choice schools in Milwaukee. The researcher identified the strategies that teachers in Choice schools in Milwaukee believe would increase teacher retention in the city. Teacher satisfaction, as well as demographic information, were examined in order to determine their potential impact on teacher retention. The researcher reviewed the literature available about the challenges schools around the country are facing as they try to retain the most effective teachers in the profession. This quantitative study used the Boylan (1993) four spheres of influence framework. The survey instrument utilized was based on the surveys used by Davis (2002) and Ulferts (2015) in their dissertation study about teacher retention in rural districts in Montana and Illinois respectively. The population selected for this study was composed of teachers in 17 schools that participated in the MPCP program during the 2018-2019 school year. This study found that the top retention factors were: support from school leaders, relationships with students, and satisfaction with salary and benefits. Boylan's whole school and within the classroom spheres had the largest amount of influence in retention of teachers in MPCP. The strategies that participants indicated to be the most effective to retain teachers in Choice schools were competitive salaries, high quality professional development, and competitive benefit packages. Results from the teacher satisfaction questions found that participants are highly satisfied with the profession at higher percentages than in the studies conducted by Davis (2002) and Ulferts (2015). The study concluded that: (1) Teachers in MPCP schools do not reflect the racial composition of the students enrolled in these schools, (2) MPCP teachers have less than six years in the profession and have been in their schools for less than three in years, (3) Whole school and within classroom spheres were the top two spheres influencing teacher retention rates in MPCP, (4) MPCP teachers rated compensation packages and professional growth as the top strategies to increase teacher retention rates, (5) Teacher turnover rates are high in MPCP schools, but the majority of teachers in these schools are satisfied with the profession.
