SACRAMENTO, Calif. – California students, from second-graders to high schoolers, will now receive history and social studies lessons about gay rights and figures, the result of a state curriculum overhaul.

The State Board of Education approved a requirement for lessons on LGBT history and leaders in a unanimous vote Thursday after four hours of testimony, a move to comply with a 2012 state law that requires schools to incorporate minority groups, Advocate.com reports.

“An outlined curriculum introduces the concepts in the second grade with discussions about diverse families and again in fourth grade with lessons on California’s role in the gay rights movement,” according to the Associated Press. “The proposed outline also touches on the topics in the fifth and eighth grades and throughout high school.”

The Los Angeles Times provided more details:

LGBT content will be included in some elementary, middle and high school grades. In fourth grade, for example, students would learn about “the emergence of the nation’s first gay rights organizations in the 1950s,” the framework states, as well as struggles in California from the 1970s to the present day to affirm the right of gay people to teach and to get married.

Lawmakers approved a the Fair, Accurate, Inclusive and Respectful Education Act in 2012 to require schools to provide history lessons with a focus on minority groups, like blacks, Hispanics, transgender and gay people.

The law’s implementation was delayed because of failed attempts to overturn it, budget issues, and other reasons, the news service reports.

The review of state history standards drew more than 10,000 emails to the California Department of Education during the three month review process that ended in February, according to the Los Angeles Times.

“The framework also adds material on voter education, financial literacy, the history of people with disabilities, and genocide,” the Times reports.

Tom Torlakson, the state’s superintendent of public instruction, applauded the additions.

“This document will improve the teaching and learning of history and social science,” he proclaimed. “It will give our students access to the latest historical research and help them learn about the diversity of our state and the contributions of people and groups who may not have received the appropriate recognition in the past.”

LGBT advocacy group Equality California issued a statement that said the state board’s decision to include “essential moments in the struggle for equality, and the evolution of communities and identities” will comfort LGBT students, according to the Times.

Committee on LGBT History director Don Romesburg told the site “it allows all students to think critically and expansively about how that past relates to the present and future roles that they can play in an inclusive and respectful society.”

It’s unclear whether that critical thinking will include opposing viewpoints on LGBT “rights” and history, or just the pro-gay perspective.
