Donald Songy was endorsed Monday by third place finisher Beth Meyers in Songy's bid to unseat Chas Roemer on Louisiana's top school board.
Roemer and Songy will face each other in a runoff on Nov. 19 for the District 6 seat on the state Board of Elementary and Secondary Education, or BESE.
Roemer led the three-candidate field in Saturday's primary election.
He got 44.7 percent of the vote to 28.7 percent for Songy and 26.5 percent for Meyers.
"I have had the privilege of getting to know Mr. Songy during this campaign," Meyers said in a prepared statement issued by Songy.
"His heart is in the right place," she said.
"I would ask that those who supported me please support Donald Songy on Nov. 19," Meyers' statement says.
Songy is a Democrat. Roemer and Meyers are Republicans.
Songy is former superintendent of the Ascension Parish school system.
Meyers is a recently retired teacher who lives in Denham Springs.
The runoff will feature sharply contrasting views on the future of public schools.
Roemer, who is seeking his second term, is an outspoken advocate of charter schools, traditional letter grades for public schools and other changes.
He is backed by Gov. Bobby Jindal and a self-styled reform group called the Alliance for Better Classrooms.
Songy is backed by the Coalition for Louisiana Public Education, which includes superintendents, school board members and teacher unions.
The group has criticized recent school changes, including letter grades for public schools and a new law that will link half of a teacher's evaluation to the growth of student achievement.
The Roemer-Songy runoff is one of three BESE contests on the Nov. 19 ballot.
BESE sets policies for an estimated 668,000 public school students statewide.
The panel has 11 members, including three appointed by the governor and eight elected by voters.
