The Pennsylvania Department of Education last week released its evaluation of the academic progress of the state’s public schools.

The School Performance Profile index is composed mainly of standardized test score results, but also takes into account attendance, graduation rates, and student improvement.

Last week, Newsworks published a story that analyzed overall state trends, as well as those in the Philadelphia School District.

The average SPP score among all Philadelphia charters for 2013-14 is 64.1– dipping slightly from last year’s average SPP of 66.

(The District’s 214 schools have an average SPP score of 56.8 – again dipping slightly from last year’s average SPP of 57.5.)
