A reasonable accommodation is an adjustment made in a system to accommodate or make fair the same system for an individual based on a proven need. That need can vary. Accommodations can be religious, physical, mental or emotional, academic, or employment-related, and law often mandates them. Each country has its own system of reasonable accommodations. The United Nations use this term in the Convention on the Rights of Persons with Disabilities, saying refusal to make accommodation results in discrimination. It defines a "reasonable accommodation" as:
... necessary and appropriate modification and adjustments not imposing a disproportionate or undue burden, where needed in a particular case, to ensure to persons with disabilities the enjoyment or exercise on an equal basis with others of all human rights and fundamental freedoms;[1]
