The market

How many occupational therapy assistants work in Washington

836 occupational therapy assistants hold an active individual NPI with a practice address in Washington, and 35 new ones enrolled in the last twelve months. A high wage with few clinicians per capita usually means employers are competing for people; a low one in a crowded market means the opposite.

Licensed in another state?

Washington has enacted the OT Compact but is not yet issuing compact privileges, so occupational therapists and occupational therapy assistants licensed elsewhere still need a Washington license for now.
