Candidates for the Oklahoma state superintendent in this year’s election include a retired dentist, a state senator and the Enid public schools superintendent. Oklahoma's current state superintendent, Sandy Garrett, is stepping down after 20 years in office. Garrett announced her retirement last year. The primary election is July 27, and the final election is Nov. 2. Potential candidates have until June to announce their candidacy. Janet Barresi, the retired Edmond dentist, has served in several education positions, including a post on the governor's Achieving Excellence in the Classroom task force. She worked as a speech pathologist in Norman and Harrah schools before going to dental school. Barresi was also involved in creating two Oklahoma City charter schools: Independence Charter Middle School and Harding Charter Preparatory High School. “As a mom, I was concerned for my sons,” said Barresi, a Republican. “At the time, no charter schools were permitted, so Independence was opened as an enterprise school until the charter law was passed.” This is Barresi's first political race. She said she wants to be a reformer. The other two candidates, Susan Paddack and Shawn Hime, did not return requests for interviews for this story. Paddack, a Democrat, is a state senator from Ada. She earned a bachelor’s degree from the University of Colorado and a master’s degree from East Central University, according to her campaign Web site. Hime, a Republican, is superintendent of Enid Public Schools. He earned bachelor’s and master’s degrees in education from East Central University. He is working to earn his doctorate from the University of Oklahoma, according to his Web site.
