Promise Student Survey Comparison School Sample
In Spring 2025, SRI researchers surveyed students at three comparison high schools—one comprehensive high school and two charter schools. SRI selected comparison schools guided by student demographics such as student gender, race, English learner, and IEP/504 status composition. SRI dropped 12th grade respondents from comparison schools to align with the Promise student population.
SRI weighted the sample of comparison students in each comprehensive high school to more closely match the student composition of Promise on five student dimensions: gender (female v. other), English learner status, special education status, grade level (12th grade v. other), and whether the student reported failing one or more courses in high school.
The following table summarizes select information about the comparison schools selected for Promise, including school type, enrollment, percent English learner, percent receiving special education services, and subset of students used. The data in this table are based off the full school sample, not respondents to the student survey.
