Updated October 30, 2026. Quick answer: Connecticut teachers can retire with an unreduced pension at age 60 with 20 years of credited service in a Connecticut public school, or with 35 years of credited service (at least 25 of them in Connecticut public schools) at any age. Early retirement opens at age 55 with 20 years (at least 15 in Connecticut public schools), or with 25 years (at least 20 in Connecticut public schools) at any age, with a reduced benefit. The vesting requirement is ten years, and the formula pays 2% for each year of Connecticut credited service.
Normal retirement
The handbook’s first route reads: “You have 20 years of credited service in a Connecticut public school and be at least age 60”. The other way is “You have completed 35 years of credited service, at least 25 of which are credited service in Connecticut public school, at any age”. The 2024 presentation repeats the age route: “You are at least age 60 with 20 years of eligible CT service”.
Early retirement
The handbook lists two doors. One: “Attained the age of fifty-five (55) and accumulated 20 years of service at least 15 of which are credited service in the public schools of Connecticut”. The other: “25 years of credited service at least 20 of which are credited service in the public schools of Connecticut at any age”. “The amount that you will receive depends on how far away you are from Normal Retirement.” “For each year or fraction thereof, you are away from Normal Retirement, there is a different Early Retirement Percentage.”
Vesting
“The current vesting requirement is ten years of credited Connecticut public school teaching service.” “You may be eligible for a Vested Deferred benefit if you leave Connecticut public school service before age sixty (60) after accruing ten (10) years of Connecticut teaching service credit.”
What the pension is based on
“2% X Credited Service in Connecticut Public Schools (“CSCPS”) X FTE X final Average Annual Salary = Normal Retirement Benefit.” “Your Average Annual Salary means the average of your three highest-paid salaries (thirty (30) months) in the public schools of Connecticut.”
A worked example with invented numbers
Take an invented teacher with 30 years of credited service in Connecticut public schools and a full-time equivalent of 1. That is 30 years at 2%, or 60% (computed) of a final average salary of $70,000 (invented, for the computation), which comes to $42,000 a year (computed).
What the documents do not say
The early retirement percentages are printed in two tables (one for under 30 years of service, one for 30 or more), so this page states none. The handbook is dated April 2018 and the 2024 presentation matches its eligibility rules, but no statute text was read. The pro-ratable benefit, disability retirement, the optional retirement plan and survivor benefits are not covered. The handbook does not set separate hire-date tiers for eligibility.
Common mistakes
- Counting out-of-state service toward the Connecticut shares. Both routes require a set number of years in Connecticut public schools.
- Expecting one early retirement percentage. The handbook says it changes for each year or fraction you are away from normal retirement.
- Leaving at 55 with fewer than 20 years and expecting to start. Early retirement needs 20 years at 55 (15 of them in Connecticut), or 25 years at any age.
