Exams are offered at a different DNR station the first Wednesday of even numbered months. New licenses are effective from the date the initial fee is received until 12/31 of the calendar year. Fees: $50 Renewal licenses are valid for 1 year beginning on 1/1 and ending on 12/31; Fee: $25; Continuing Education: 6 hour continuing education class.
