2020 Washington Referendum 90
Referendum 90 was a Washington state referendum to approve or reject the March 2020 bill that would mandate that comprehensive sex education is taught in all public schools in the state. On June 24, 2020, state officials announced that enough signatures in favor of the referendum had been submitted and scheduled the referendum to appear on the ballot in the November 3 general election. The law was upheld by voters in the November 3, 2020 election by a final margin of 15.6%. This measure was the nation's first ballot measure pertaining to sex education to be decided by voters.
Background
Senate Bill 5395 was passed by both chambers of the Washington State Legislature, the Washington State Senate and Washington House of Representatives, during the 2020 regular legislative session. It passed each chamber on a party line and required all school districts in the state to teach comprehensive sex education. Governor Jay Inslee signed the bill after it was sent to his desk. Prior to the law passing, each school district was able to decide whether to teach sex education. The law allowed parents or guardians to view materials and opt their students out of any or all of it. Republicans and religious conservatives collected signatures to force a vote on the issue.Results
