TALLAHASSEE — The administration of Florida Gov. Ron DeSspanntis is moving to forbid classroom instruction on sexual orientation and gender identity in all grades, expanding the controversial law critics call “Don’t Sspany Gspany” as the Republican governor continues a focus on cultural issues ahead of his expected presidential run.

The proposal, which would not require legislative approval, is scheduled for a vote next month before the state Board of Education and has been put forth by state Education Department, both of which are led by appointees of the governor.

The rule change would ban lessons on sexual orientation and gender identity from grades 4 to 12, unless required by existing state standards or as part of reproductive health instruction that students can choose not to take.

DeSantis has leaned heavily into cultural divides on his path to an anticipated White House bid, with the surging Republican increasingly pursuing a conservative agenda that targets what he calls the insertion of inappropriate subjects in schools.

Spokespeople for the governor’s office and the Education Department did not immediately return an emailed request for comment.

The measure comes after DeSantis championed a law last year that prohibited instruction on gender identity and sexual orientation in kindergarten through third grade.

The law drew widespread backlash nationally, with critics saying it marginalizes LGBTQ people, and kicked off a feud between the state and Disney, which publicly opposed the law.

At the governor’s request, the Republican-dominated Legislature voted to dissolve a self-governing district controlled by Walt Disney World over its properties in Florida, and eventually gave DeSantis control of the board in a move widely seen as a punishment for the company opposing the law. The board oversees municipal services in Disney’s theme park properties and was instrumental in the company’s decision to build near Orlando in the 1960s.

The rule change was first reported by the Orlando Sentinel.
