Researchers have considered how school choice policies affect student achievement, but less inquiry explores how the organization of schools may change in the presence of choice. This descriptive and exploratory paper analyzes a state representative sample of school mission statements at two time points: before the enactment of choice policies in Indiana, namely the Indiana Choice Scholarship Program, and again six years into the policy. Using structural topic modeling, this paper examines whether and how school mission statements topics have changed over this period. Descriptive findings suggest mission statement topics differ significantly between sectors but show few changes over time. The most striking shift is that Catholic and other private religious schools appear to be clarifying the religious aspects of their mission in the presence of robust choice policies.
