Just because a child has a disability or impairment does not mean that he/she automatically qualifies for special education services under the IDEA. A child with a disability who does not need special education services will not qualify for special education and related services under the IDEA. He or she may however receive protections under Section 504 of the Rehabilitation Act.
Eligibility for protections under Section 504 depends on the child in question having a physical or mental impairment which must substantially limit at least one major life activity. Major life activities include walking, seeing, hearing, speaking, breathing, learning, reading, writing, performing math calculations, working, caring for oneself, and performing manual tasks. As you see, many activities are included under this category. The question that must be addressed by the school's special education team is whether the child has an "impairment" that "substantially limits one or more major life activities."
