California’s Board of Education has officially added sections on the LGBT civil-rights movement and history to public school curriculums through out the state.

Officials voted unanimously to update the social-studies curriculum, but the idea was met with resistance when it was first floated several years ago.

“The framework tends to normalize and reinforce things that have led to negative social and human consequences in society… with the intention of depriving them of the fundamental right of being in relationship with their own mother, father or both,” said Bill May, head of the Bay Area-based Catholics for theCommon Good Institute.

Governor Jerry Brown actually approved a measure adding LGBT topics to the classroom back in 2011. But opposition by conservatives slowed its execution.

“History is not just ‘who was king or queen when’,” state Superintendent of Public Instruction Tom Torlakson told the San Francisco Gate. The new curriculum is “not only acknowledging diversity, but celebrating our diversity as a strength,” he said.

According to the Board’s framework, LGBT history and issues will be introduced starting in the second grade, with age-appropriate content like stories with same-sex parents or trans characters.

In the fourth grade, they’ll learn about the historical struggle for LGBT equality and the landmark 2015 SCOTUS case that brought marriage equality to all 50 states.

Then, in 11th grade, the curriculum becomes more nuanced, with a discussion of identity issues and the contemporary debate on gay rights.

It’s great news—and a model we hope other states follow.

Now if we could only get LGBT issues incorporated into health class.
