New York Gov. Andrew Cuomo has rejected legislation that for two years would have discounted Common Core-aligned student test scores in state-mandated teacher evaluations.
In his veto message, Cuomo says the bill is "unnecessary" because the recently released 2013-2014 evaluations rated fewer than 1 percent of teachers ineffective, adding that the evaluations "are not an accurate assessment."
The bill would have also applied to evaluations for teachers and school principals in the current school year.
New York's largest teachers union accused Cuomo of reneging on an agreement.
Cuomo says he will propose "comprehensive reforms" to the performance review system next year to "strengthen" it.
