Republican Geraldine "Tincy" Miller will advance to a runoff for the nomination for the District 12 spot on the state Board of Education. Her opponent isn't clear yet.
The winner of the runoff will face the Democratic nominee in the general election Nov. 6.
Miller, of Dallas, first began serving on the state board in 1984. She was defeated in the primary in 2010. The incumbent is George M. Clayton, a special projects coordinator for Thomas Jefferson High School in the Dallas district.
All 15 board spots are up for re-election following redistricting last year. District 12 includes Collin County and part of Dallas County.
The board's responsibilities include establishing the state's public school curriculum, approving textbooks and managing the state's permanent school fund.
