The Arizona Supreme Court has ruled that the financially strapped state owes its public schools $317 million in funding that it failed to provide during the recession, the Arizona Republic reported. And it may become worse for the state. The total debt to the schools could be $2.9 billion over the next five years. Even so, the change will not restore the schools to pre-recession funding levels. “For anyone to characterize this as a windfall for the schools, that would be a mistake,” Chris Thomas, general counsel for the Arizona School Boards Association, told the Republic. The ruling was based on a 2000 ballot question that approved adjusting to the school-funding formula for annual inflation.
