The Post-Gazette's recent coverage of a report on charter school performance ("Study: Pa. in Bottom Three for Charter School Scores," June 26) left out a significant local angle. The Stanford University researchers have also reported, using the same methodology, on the performance of organizations running multiple charter schools, including Pittsburgh's own Propel Schools.
According to the researchers, Propel students are getting the equivalent of an extra 72 days of instruction in reading (0.1 standard deviations) and 108 days of instruction in math (0.16 standard deviations) every year compared to students attending district-run schools.
That's a terrific and important result particularly in the context of this national study by the same authors that generally notes huge variations in school performance.
Propel stands out.
