This latest effort is a part of the NAACP’s attempt to fight what they describe as a wave of anti-diversity, equity and inclusion legislation across the country.

The lawsuit argues that the Advanced Placement African American Studies classes taught in Arkansas’ public schools have received inequitable treatment and have been marginalized and underfunded when compared to other advanced placement courses. The suit claims that the alleged inequities have both deprived students the opportunity to learn about African American history and contributions, and have maintained a level of systemic inequality.

“We refuse to go back. The NAACP will continue to use every tool at our disposal to ensure that our constitutional rights are protected, and our culture respected. This is what standing for community looks like,” NAACP President Derrick Johnson told ABC News.

Johnson added, “From Arkansas to Alabama, the desecration of diversity, equity and inclusion poses an imminent threat to the future of our nation.”
