Oregon PERS Tier One, Tier Two or OPSRP: one date decides

Oregon PERS has three pension programs. Which one you're in depends on when you were first hired into a Oregon PERS job, and it sets your formula, your full-benefit age and more.

Oregon PERS decides the program by when the six-month wait time started, not when it ended (hired Dec. 1995 and finishing wait time in 1996 = Tier One). The program never changes unless membership is lost or withdrawn; a member who rejoins after that is OPSRP. Judges have a separate plan and are not in OPSRP. Oregon PERS Employer Guide Ch. 1 (Sept. 2026), pp. 8-9; Oregon PERS webpage 'What plan am I in?'

OPSRP stands for the Oregon Public Service Retirement Plan. The 2003 Legislature created it.

Everyone: the IAP

Since Jan. 1, 2004 every Tier One, Tier Two and OPSRP member also has an Individual Account Program (IAP) account: 6% of salary (paid by the member or picked up by the employer) invested in a target-date fund, with no guaranteed return. Members retire from the IAP when they retire from the pension, and must be separated from all Oregon PERS employers to do so. Oregon PERS Benefit Comparison Chart (Dec. 2024), p. 1; Oregon PERS Employer Guide Ch. 1 (Sept. 2026), p. 11; Oregon PERS OPSRP Preretirement Guide (June 2026), p. 5 How the IAP works

Since 2020, part of the 6% can go to an Employee Pension Stability Account instead, in months when your pay is over $3,890 (2026).

What the sources say

Questions

What date decides my tier?

The date you were first hired into a job that qualifies for Oregon PERS: more exactly, when your six-month waiting period began. Someone hired in December 1995 who finished the wait in 1996 is still Tier One.

Can my tier change?

No, unless you withdraw your account or lose membership. If you come back after that, you join OPSRP.

What is the IAP?

The Individual Account Program: since Jan. 1, 2004, 6% of every member's salary goes into an investment account, on top of the pension.

Are judges in OPSRP?

No. Judges have a separate Oregon PERS plan, which this site doesn't cover.
