Gov. Jan Brewer has vetoed a bill that would have prevented Arizona from adopting any federally mandated school standards or teaching approaches.

House Bill 2316 was the lone survivor of efforts by the GOP-controlled Legislature this year to keep the state from implementing new Common Core teaching standards.

But Brewer said in a veto message Thursday that it was redundant and unnecessary because the state's standards weren't developed or mandated by the federal government. She said the law also could have stopped the state from requiring schools to teach phonics-based early reading programs or enforcing English Language Learner program requirements.

The bill by Republican Reps. Tom Forese and Justin Pierce would also have tightened some student privacy laws.
