I compared the average performance composites of all regular/traditional public schools and all charter schools. (Note: All schools classified by the Department of Public Instruction as “alternative” were not included.) The performance composite is the percentage of students performing at or above grade level (Level III) on all state tests taken at the school during the 2010-11 school year.
Last year, the average performance composite of 2,351 regular/traditional schools was 76.1 percent. The average performance composite of 98 charter schools was 79 percent.
