Charter schools run by teachers unions do not perform as well as non-union charter schools.
A New York Post op-ed cites that Beginning With Children Charter School, located in Brooklyn, NY, is closing its doors because it was not able to make necessary reforms due to their contract with the United Federation of Teachers (UTF):
The UFT dominates the traditional schools. The UFT charter can’t compete with the non-union charters. And officials at the Beginning With Children Charter School say it is closing because the UFT contract doesn’t allow reforms that include more teacher training, longer school days and better teacher evaluations.
