Title IX applies to high schools in the United States. Title IX is a federal law that prohibits sex-based discrimination in educational programs and activities, and it covers all educational institutions that receive federal funding, including K-12 public schools, which include high schools. Therefore, high schools are required to comply with Title IX regulations, ensuring equal opportunities and protection against sex-based discrimination for their students and staff. This includes addressing issues like sexual harassment, gender-based violence, and providing equitable opportunities in sports and other educational activities.
