Regulation B3 Concurrent full-time and part-time service
Notwithstanding anything in regulation B2, a teacher is not in pensionable employment in respect of any part time service on or after 20th November 2000 which is additional to concurrent full time service unless–
he or she was in part time service additional to concurrent full time service immediately prior to 20th November 2000; and
he or she has continued in such part time service additional to concurrent full time service.
A teacher to whom paragraph (1) applies may elect that such part time service shall cease to be treated as pensionable employment, and an election for this purpose may be made at any time by giving written notice to the Scottish Ministers and shall have effect from the first day of the month after that in which it was given.
