The Houston Independent School District (HISD), the largest school district in Texas and one of the largest in the nation, will have its superintendent and board of education trustees replaced by a new board appointed by the state Commissioner of Education. This move has angered Democrats, and deepens a rift between Texas' largest city and state Republican leaders. It is unclear what changes the new board will make, who will be appointed, or what impact the takeover will have on the district's students and staff.
