Some are treated the same as actual Connecticut public school teaching service and some are considered as Non-Connecticut. It is your responsibility to document additional credited service on the appropriate form(s). Lack of the required information requested on the appropriate additional credit forms will cause delays in processing a cost statement.

If you were an active contributing member of TRB and also were employed as a part-time lecturer at a CT State College or University, you may elect to include such earnings as part of your pensionable salary. Please be advised if you are currently working as a regular public school teacher and a part-time lecturer, you need to contact the university or college payroll office regarding your eligibility to enroll in CTRB and include your earnings as part of your pensionable salary, which may have an effect in determining your highest 3-year average at the time of your retirement.
