What it is

A general description of the work. Scope, which is set in law, is covered topic by topic below.

Commonly works on

  • Daily living skills
  • Therapeutic activities
  • Adaptive equipment

Typical settings

  • Skilled nursing
  • Schools
  • Hospitals
  • Home health

Occupational therapy assistants provide occupational therapy services alongside occupational therapists, to people of all ages in homes, schools, community settings, hospitals, nursing homes and outpatient clinics. AOTA describes occupational therapy services as provided by both licensed occupational therapists and licensed occupational therapy assistants.

Entry is through an ACOTE-accredited assistant program at the associate degree level. Graduates sit a separate NBCOT examination from the one for therapists; passing it confers the COTA credential.

As with therapists, NBCOT certification and a state license are separate. NBCOT points certified practitioners to the additional steps needed for a license, and each state sets how an occupational therapist must supervise an assistant.

A general description of the profession. It does not say what you may do under your license; for that, see the scope statuses below and your state board.

How it is regulated

The national layer. States add their own requirements, and the state board has the final word.

National certification, then a state credential

A national body sets the entry standard and certifies people who meet it. States then regulate practice on top of that, by license, certification or registration depending on the state. The two layers are separate obligations, each with its own renewal.
