504 plan
(… plan)
An education plan for students with disabilities or certain health conditions, such as cancer. By law, these students must have the same access to school programs and activities as students without disabilities. A 504 plan may include extra help in the classroom, such as allowing the student more time to take a test or finish an assignment, or to use a computer or tape recorder. It may also include tutoring and other services, such as speech therapy and physical therapy. It is covered under the U.S. law, Rehabilitation Act of 1973.
