Regulations are used to protect consumers in a state or jurisdiction. These regulations protect from unqualified, unscrupulous, or unethical OT practitioners.
Regulations are developed by regulators, who are appointed public officials of various departments in state government.
In the USA, Occupational Therapy is regulated in all 50 states, the District of Columbia, Puerto Rico and Guam.
Different states have various types of regulations. The strongest form of regulation is licensure.
Most states, the District of Columbia, and Puerto Rico require occupational therapists and occupational therapy assistants to be licensed. A few states have certification or registration by a state agency.
States have similar, but not identical requirements and procedures for obtaining an OT license.
For an up to date, state-specific, licensure requirement, consult the state occupational therapy regulatory agency at your state.
