Section 504 was established to ensure a free appropriate education for all children who have an impairment-physical or mental-that substantially limits one or more major life activities. If it can be demonstrated that a child's ADHD adversely affects his or her learning-a major life activity in the life of a child-the student may qualify for services under Section 504. To be considered eligible for Section 504, a student must be evaluated to ensure that the disability requires special education or related services or supplementary aids and services. Therefore, a child whose ADHD does not interfere with his or her learning process may not be eligible for special education and related services under IDEA or supplementary aids and services under Section 504.
