In the U.S. Individuals with Disabilities Education Act (IDEA), least restrictive environment (LRE) means that a student who has a disability should have the opportunity to be educated with non-disabled peers, to the greatest extent appropriate. They should have access to the general education curriculum, or any other program that non-disabled peers would be able to access. The student should be provided with supplementary aids and services necessary to achieve educational goals if placed in a setting with non-disabled peers.
Academically, a resource room may be available within the school for specialized instruction, with typically no more than two hours per day of services for a student with learning disabilities. Should the nature or severity of his or her disability prevent the student from achieving these goals in a regular education setting, then the student would be placed in a more restrictive environment, such as a special school, classroom within the current school, or a hospital program. Generally, the less opportunity a student has to interact and learn with non-disabled peers, the more the placement is considered to be restricted.
LRE is one of the six principles that govern the education of students with disabilities and other special needs. By law, schools are required to provide a free appropriate public education (FAPE) in the least restrictive environment that is appropriate to the individual student's needs.
To determine what an appropriate setting is for a student, a team will review the student's strengths, weaknesses, and needs, and consider the educational benefits from placement in any particular educational setting. With the differences in needs varying broadly, there is no single definition of what an LRE will be, and each student has an Individual Education Plan (IEP).
