Controversy

In July 2024, the ACLU of Texas sent Santo Independent School District a letter, alleging that the district's 2023-2024 dress and grooming code appeared to violate the Texas CROWN Act, a state law which prohibits racial discrimination based on hair texture or styles, and asking the district to revise its policies for the 2024-2025 school year.
