Yes, licensees can carry over excess hours, up to one-half of the previous biennial (two-year) requirement.
For example, if you are a professional engineer and accrued 47 hours in a renewal period (17 more than the 30 hours required), you may carryover a maximum of 15 hours into the next renewal period, as 15 hours is half the biennial requirement of 30.
If you are an architect and accrued 42 hours in a renewal period (18 more than the 24 hours required), you may carryover a maximum of 12 hours into the next biennial renewal period, as 12 is half of the biennial requirement of 24.
