SACRAMENTO-- The California State Board of Education has unanimously approved a new set of rules giving parents more power to force changes at poor-performing schools.

The regulations were approved Wednesday before a packed meeting room in Sacramento. Parents who had taken buses from across the state erupted in cheers.

The action isn't the final word, however. The proposed regulations will be put out for public comment for 15 days and could be challenged.

The so-called "parent trigger" rules have been controversial.

A petition to convert a Compton Unified School District elementary school into a charter school has already wound up in court. Last week, parents also filed an ethics complaint against a state school board member, saying she worked for a teachers union and should not be voting on the issue.
