Discover key findings

Charter school students have an average of 16 more days of learning in reading and 6 more days in math in a school year compared to their matched peers in TPS.

Students in poverty, Black and Hispanic students in charter schools have stronger growth than their TPS peers. But, gains are not equal to their white peers, creating learning gaps for many students.

Across our three national charter school studies, annual charter student learning in reading has risen by 22 days; math learning has increased by 23 days.

Compared to TPS, students enrolled in CMO-affiliated schools progress in their learning in reading by 27 extra days in a year and math by 23 extra days. Stand-alone charter schools (SCSes) also outpace their TPS peers in reading by 10 extra days of learning a year; math progress was equivalent.

Students receiving special education services who attend charter schools have smaller learning gains than their matched peers in TPS.

Across the 31 states in the study, the spread between the state with the best learning result and the worst outcome is 109 days of learning in reading and 120 days in math.
