FAQs for Employers

When is a substitute teacher eligible for membership in Connecticut Teachers' Retirement System?

A substitute teacher is eligible for membership in the Connecticut Teachers' Retirement System if he/she is employed as a permanent substitute teacher for ten months during full school year.

In order to qualify for membership as a permanent substitute teacher ALL three of the following conditions must be met:

  • Employment as a substitute teacher must begin on or before the first working day of September.
  • The individual is expected to work the full school year in the same assignment.
  • The individual completes the full school year in the same assignment.

If you hire a teacher as a permanent substitute with the expectation that he/she will work the full school year in the same assignment, you will be expected to initiate mandatory retirement contributions.
