Free and Appropriate Public Education (FAPE)

An educational right of children with disabilities in the United States that is guaranteed by the Rehabilitation Act of 1973[1] and the Individuals with Disabilities Education Act (IDEA). Under Section 504, FAPE is defined as "the provision of regular or special education and related aids and services that are designed to meet individual needs of handicapped persons as well as the needs of non-handicapped persons are met and based on adherence to procedural safeguards outlined in the law." Under the IDEA, FAPE is defined as an educational program that is individualized to a specific child, designed to meet that child's unique needs, provides access to the general curriculum, meets the grade-level standards established by the state, and from which the child receives educational benefit. The United States Department of Education issues regulations that define and govern the provision of FAPE.

To provide FAPE to a child with a disability, schools must provide students with an education, including specialized instruction and related services that prepare the child for further education, employment, and independent living.

A FAPE is expected to meet the unique educational needs of the student to address both academic needs and functional needs of the student.  The school must provide "...access to the general curriculum to meet the challenging expectations established for all children".

Learning Disability, Learning Difference, Learning Disorder or Learning Difficulty (LD)

A learning disability results from a difference in the way a person's brain is "wired." Children with learning disabilities are as smart as or smarter than their peers. But they may have difficulty reading, writing, spelling, reasoning, recalling and/or organizing information if left to figure things out by themselves or if taught in conventional ways.

A learning disability can't be cured or fixed; it is a lifelong issue. With the right support and intervention, however, children with learning disabilities can succeed in school and go on to successful, often distinguished careers later in life.
