As reported in Governing, The National Alliance for Public Charter Schools has released its first state-by-state ranking of public charter school systems, with the District of Columbia and Louisiana claiming the top two positions.

In D.C., 44 percent of all students attend charter schools, which produce 72 more days of reading growth and 101 more days in math, according to the report. Louisiana, another state praised by charter-school advocates following the remaking of New Orleans schools after Hurricane Katrina, scored particularly well because of its high growth rate, the number of poor students its charter schools serve and academic growth compared with other public schools in the state.

The National Alliance focused on schools whose charter school movement served at least one percent of their public school students in 2013-14 and who participated in the Center for Research on Education Outcomes’ 2013 National Charter School Study.  Maryland is not scored in the report.
