There is a second bond proposal on the ballot for $500,000 for transportation equipment. A similar proposal also failed in November 2011.
There are 6,944 registered voters in the school district, according to the Canadian County Election Board.
For the last bond issue, almost 2,000 people came out to vote and the proposal was defeated, failing to reach the required 60 percent majority for school bond issues.
Early voting can be done at county election headquarters on Friday and Monday 8 a.m. until 6 p.m. There is no early voting on Saturday because there are no statewide issues on the ballot.
Precincts open for the elections at 7 a.m. on Tuesday. Voters need a valid form of identification like a state-issued driver's license or a voter identification card issued by county election boards to all voters.
Other elections in the metro area include a proposed 1 percent sales tax in the Town of Luther to fund a number of capital improvements.
