Missouri Gov. Jay Nixon has vetoed a bill aimed at revamping the state's student transfer system.
Nixon on Friday criticized expanded options for virtual schools and said the bill didn't address key issues with current law.
Failing schools now must pay tuition if students decide to transfer elsewhere. Districts say that's caused financial hardship as they work to regain accreditation.
Nixon also cited the lack of a tuition cap in his veto. He said without that, schools that are struggling the most would continue to lose resources.
