A licensee shall complete 12 LUs during each of the 2 preceding calendar years that occur prior to the calendar year in which an applicable license term is set to expire. As an alternative to §A of this regulation, a licensee shall complete 24 LUs during the 2-year term of the license ending on the date that the license term is set to expire. If a licensee chooses the calendar year method, as described in §A of this regulation, the LUs from each calendar year shall be considered separately. A licensee may not carry forward any LUs earned in excess of the annual requirement of 12 LUs to any following calendar year. If a licensee chooses to complete 24 LUs during the 2-year term of the license, as described in §B of this regulation, the licensee may not carry forward any LUs earned in excess of the required 24 LUs to the following 2-year term of the license. LUs used to meet the requirements described in §A of this regulation may not also be used in the future to meet the requirements described in §B of this regulation. In a similar way, LUs used to meet the requirements described in §B of this regulation may not also be used in the future to meet the requirements of §A of this regulation.
