Section 504 is a federal law that prohibits discrimination against individuals with disabilities. It requires schools to provide accommodations to eligible students to ensure equal access to the learning environment and activities. The key aspects of Section 504 include evaluating students for eligibility, developing accommodation plans, reviewing plans annually, reevaluating every three years, and establishing disciplinary guidelines for students with disabilities. Parents have certain rights under Section 504 including consent for evaluations and notice of referrals and placements.
