The National Alliance for Public Charter Schools on Tuesday announced the release of the third annual rankings of state charter school laws across the country - and Arizona's law fell from 11th to 15th.
Measuring Up to the Model: A Ranking of State Public Charter School Laws analyzes the country's 42 state laws. Each state is scored on how well it supports charter school quality, accountability and growth.
Arizona's law dropped because other states made significant jumps in their ranking.
There were 508 charter schools in Arizona last year, comprising more than 23 percent of the state's public schools. More than 11.5 percent of public school students were attending charters in Arizona, according to an earlier report released by the National Alliance for Public Charter Schools.
