The purpose of this study was to compare motivations of teachers in P-12 private school settings with those in public school settings in a midwestern state in the United States. Through convenience sampling, 2,315 surveys were sent out with 73 private and 234 public school teachers agreeing to participate. Descriptive statistics and t tests revealed that teachers from private schools responded statistically significantly lower than teachers on intrinsic career value (d = -0.48), job security (d = -0.47), family time (d = 1.04), social equity (d = -0.43), work with children (d = -0.41), prior experience (d = -0.46), and social influences (d = -0.43). The teachers from private schools scored statistically significantly higher on difficulty (d = 0.68), social dissuasion (d = 0.42), and satisfied teaching (d = 0.41) factors. The findings suggest that teachers in private and public-school settings are motivated to teach for different reasons.
