I previously wrote about SB 1290. Yesterday Governor Brown signed the bill into law. It requires "the chartering authority to consider increases in pupil academic achievement for all groups of pupils served by the charter school as the most important factor in determining whether to grant a charter renewal." It also requires that performance by each student group be broken out separately and each of those groups individually must show improvement.
This is a very welcome improvement to charter law, and I'm hopeful it will give school boards a useful tool to stand up against boutique charters that do nothing to improve educational outcomes.
