What law generally prohibits the denial of educational participation due to a child's disability?

The correct response highlights Section 504 of the Rehabilitation Act as the pivotal legislation that prohibits discrimination against individuals with disabilities in any program or activity receiving federal financial assistance, including public education. This law ensures that students with disabilities have equal access to educational opportunities and services, thereby preventing the denial of educational participation based on disability.

While the Individuals with Disabilities Education Act (IDEA) is crucial for ensuring that students with disabilities receive a free appropriate public education specifically tailored to their needs, Section 504 encompasses a broader scope of non-discrimination, applying to all aspects of educational participation, including accessibility and accommodations. The Education for All Handicapped Children Act (EAHCA) is an earlier version of IDEA and does not provide the same level of general anti-discrimination protections that Section 504 does. The Rehabilitation Act of 1973 is a landmark law that includes Section 504, but the specific emphasis on educational participation in the question pertains directly to Section 504.
