The superintendent of the Dallas Independent School District has quit after nearly three years on the job.
Mike Miles cited family reasons in announcing his resignation Tuesday, effective Thursday.
Miles joined DISD in July 2012 after six years as superintendent of the Harrison School District in Colorado Springs, Colorado. Miles said it's time to rejoin his family in Colorado.
Miles received a two-year contract extension last July but no raise. He made about $300,000 annually.
Miles, who this month fired three principals despite a school board vote to keep them, cited achievements including an updated teacher evaluation system. He also mentioned an increased focus on early childhood programs.
Deputy Superintendent Ann Smisko will serve as interim superintendent. Dallas has the state's second-largest public school district with about 160,000 students.
