 In 2014, the Coolidge district closed Mountain Vista and moved its students and teachers to the San Tan Foothills campus.In order to save significant costs for Coolidge, and make a third high school in the district (second in San Tan Valley) unnecessary, the Florence Unified School District voted to acquire CUSD's three San Tan Valley schools in 2015.The move was approved by voters in both districts in overwhelming margins that November.
