023Membership tier
Texas TRS has six membership tiers. Your tier is fixed by when you joined, your grandfathered status, and your service on August 31, 2014 — and it decides whether the Rule of 80 comes with a minimum age of none, 60, or 62.
024Eligibility
The Rule of 80 means your age plus years of service credit reach 80 — but which version applies to you depends on when you joined TRS, and newer members also need a minimum age. Four worked examples show how it plays out.
025Eligibility
TRS Texas uses the Rule of 80, not a Rule of 90 — that provision belongs to teacher pension systems in other states, like Minnesota's. Here's where the confusion comes from and what actually applies in Texas.
