About Section 504
Section 504 is a federal statute (anti-discrimination law) which protects the rights of individuals with disabilities to equal opportunity in programs and activities which receive federal funds. Section 504 is intended to level the playing field for individuals with disabilities, so students can fully participate in academic and extracurricular activities.
