This brief report supplements CREDO’s June 2009 national study on charter performance in 15 states and the District of Columbia. The January 2010 report focuses on the school years 2003-04 through 2008-09, and looks at roughly 20,000 students in grades 3-8 across 49 New York City charter schools.
The results of the New York City report show significantly better results for most students and student subgroups in math (with the exception of students with disabilities, Limited English Proficient students, retained students, and students in poverty) and better results for students in reading (students enrolled for 1 year, students with disabilities, Limited English Proficient students, and retained students).
Although there are a number of differences between the national study and the NYC study – including vastly different results in mathematics, wherein more than half of the NYC charter schools showed statistically significant growth in math, as compared to just seventeen percent in the national study – one common theme is that students enrolled in charters seem to perform better over time. Specifically, the New York City report indicates that after three years in a NYC charter school, students showed a four point advantage in reading and 15 point advantage in math as compared with students in traditional public schools. Copies of both the New York City and national reports are available here.
