Proposed legislation by a Florida Republican would prohibit young girls from discussing their menstrual cycles with school officials while seeking to limit sex education in schools.

Rep. Stan McClain’s (R) House Bill 1069 would restrict the educational materials used in state schools to only occur in grades 6 through 12.

The legislation also requires schools to teach that “sex is determined by biology and reproductive function at birth” and that “these reproductive roles are binary, stable, and unchangeable.” Additionally, the bill would require all educational materials to be approved by the state Department of Education and allow parents to limit their children’s access to library books.

This is the latest in a string of conservative education bills from Florida.

The Florida House subcommittee passed the bill in a 13-5 vote split along party lines.
