In a surprise, the superintendent said she would resign if trustees moved forward with the plan Thursday night.

Many described the split as a move to cut out students who “live on the wrong side of the tracks,” referring to the rail line along Denton Highway that serves as the border between Keller and Fort Worth, saying the board intended to racially segregate schools in the district. They also said they were “blindsided” by how the idea was made public.

Tensions were high last night at the Keller ISD meeting to discuss splitting the district in two. Keller ISD's superintendent spoke up, saying she did not agree with the proposal and is willing to resign.
