Continuing education hours can only be credited within the current biennium dates in which they are taken. A licensure biennium is the twenty-four month period between expiration dates. All occupational therapists, occupational therapy assistants, and occupational therapy continuing education provider licenses expire on February 28 of every odd year. New hours may be accrued on or after March 1, odd year. It is during this time period that the continuing education requirements must be met for each renewal cycle. You may visit the Boards Renewal page to see the CURRENT RENEWAL DATES.
