The purpose of this study is to ascertain the opinions of chief executive officers (CEOs) and school board chairs of Texas private schools in educational service center (ESC) Regions 10 and 11 toward board training and the potential benefits for the success of their respective roles. Literature regarding private school board training is limited. As a result, most private school boards face challenges regarding school board training expectations, which could affect their roles and the roles of CEOs. The quantitative and qualitative cross-sectional research design examined Texas private school CEOs’ and school board chairs’ perceptions about school board training and the working relationships between Texas school CEOs and school boards. The researcher developed the survey and interview questions used in this study. Responses to a 4-point Likert-type scale instrument, short answer questions, and interviews were solicited from a population of private school CEO and school board chairs within ESC Regions 10 and 11 from schools with an enrollment of at least 100 students and that contained Grades 9 through 12. In-depth Interviews were conducted with 12 private school CEOs and 12 school board chairs with varying levels of school board training. The research findings indicate that board training does make a significant difference in the working relationships between CEOs and private school boards. The findings of this study may assist private school boards in addressing school board training and the components of such training, which would benefit the working relationships between CEOs and school boards, as well as the success of private schools.
