The study examined the effect of 60 New Jersey charter schools on annual student achievement growth in reading and math. The study was based on data from a large sample of students in grades 3-8 during 5 school years (2006-07 through 2010-11). The study authors matched charter school students to students attending traditional public schools based on test scores and demographic characteristics. This matching process was conducted separately for each of the 5 study years. At least one match for 77% of charter school students in the sample (a total of about 16,500 students) could be identified. Study authors assessed the effectiveness of the charter schools by comparing average 1-year achievement gains of charter and comparison students on standardized reading and math tests. This calculation was based on the pooled sample of students in grades 3-8 across the 5 study years. The study authors reported that 1-year reading and math achievement gains of students in the charter schools were significantly greater than those of comparison students in traditional public schools. Charter school effects in Newark were positive, statistically significant, and larger than for New Jersey overall, while charter school effects for the other major cities in New Jersey were negative and statistically significant in reading and zero in math. The authors also examined charter school effects separately for Newark (a major city in New Jersey) and a collection of other major cities (Camden, Jersey City, Paterson, and Trenton).
