DALLAS (CBSDFW.COM) – The Dallas ISD Board of Trustees has voted to close 11 schools in a cost-cutting measure slated to save the district $11.5 million for the 2012-2013 school year.

Students at those 11 campuses will be dispersed to nearby schools.

The controversial vote passed 6-2 Thursday night in a board meeting highlighted by heated debate.

At one point in the evening several trustees stepped away from the meeting due to protests and angry speakers, retreating to a smaller room at district headquarters to conduct the meeting via a closed-circuit TV.

Trustees who favor closing the 11 schools, argue that it will save the district from laying off 171 teachers next year in order to cut costs.

Although the district says closing the schools will save $11.5 million, DISD still needs to cut another $13.5 million by June.

The school board also voted to increase the workday for teachers by 45 minutes.
