Conn. Agencies Regs. § 10-183l-2
A member who commences service as a teacher other than at the start of the school year is not entitled to a month of credited service for the month in which the pay for such teacher starts accruing after the first working day of the month but shall be entitled to credit for one month of service for any month for which pay is accrued so long as the person is employed on the first working day of the month. Thus, if a member starts service on October 15th of a school year and works until June 20, the last day of the school year, the member would receive eight months of credited service for that school year. Similarly, a member who terminates service as a teacher other than at the finish of a school year is not entitled to a month of credited service for any month after the month in which service terminates. Thus, if a member starts service on September 5, the first day of the school year and terminates service on the following February 10, the member would receive six months of credited service for that school year.
