On December 9, 2020, the filing deadline passed to run for 33 school board seats across 26 school districts covered by Ballotpedia in Oklahoma. Of the 58 candidates who filed in these school board races, 24 are incumbents seeking re-election to their seats.
The primary is scheduled for February 9, 2021, and the general election is scheduled for April 6, 2021. In Oklahoma, school districts cancel primary elections if fewer than three candidates file to run for each seat up for election, and the candidates automatically advance to the general election. Both the primary and general elections are canceled if only one candidate files for a seat up for election, and the unopposed candidate is automatically elected.
The largest school district covered by Ballotpedia and holding elections in Oklahoma in 2021 is Oklahoma City Public Schools. The district served 39,806 students during the 2016-2017 school year.
