School choice is a research topic that is often associated with public funds supporting educational alternatives. While much of the school choice research literature focuses on this category, additional types of school choice merit examination. This study examines how Catholic parents chose high schools for their children within the geographic boundaries of the Roman Catholic Diocese of Albany (RCDA), New York. The purposes of the study were to explore whether these parents selected Catholic or public schools for their children, factors that influenced their decisions on school placement, and sources of information about schools that assisted with the decision-making process. Study findings were derived from a survey administered to parents who resided in the RCDA, had a child in the household in grades 10-12, and had enrolled their child in a Catholic faith formation program. The findings revealed several similarities and differences in the decision-making process of parents who selected Catholic schools and those who selected public schools. The majority of survey respondents (83.3%), selected public schools for their child's high school. Parents who selected Catholic schools and those who selected public schools shared some similarities in terms of income, education, and church attendance. When it came to school factors, the study discovered statistically significant differences between the two groups in terms of preferences for single sex education, moral and character education, religious education and worship, and a disciplined and orderly school environment. The two groups of parents shared some similarities in factors that influenced their school choices including concerns about quality of academic program, distance of school from home, family history of attending Catholic or public schools, financial considerations, school safety, school reputation, student services, and athletic programs. Lastly, the study discovered that those who selected Catholic schools and those who chose and public schools relied on different types of information about schools. The results of this study will assist researchers, educational policy makers, and school leaders in better understanding how parents choose schools.
