Pension plans can be designed to provide portability, but neither TRSIL or CTPF benefit provisions don’t offer any such features. Teachers who leave before vesting will get their own contributions back, but without even the nominal interest they would have earned in a basic savings account. None of the employer contributions made on behalf of members are portable, depriving them of deferred compensation that has been earned.
Teachers in Tier 2 have to wait ten years in order to vest and be qualified to receive a future benefit upon retirement. Fully half of Illinois teachers leave before this point. Any educator who moves away from Illinois or leaves public school teaching before vesting leaves behind their retirement plan and much of the retirement income they have accumulated. Illinois teachers also do not participate in Social Security, meaning they lack the additional, portable safety net retirement plan that most other Americans have.
There is currently no option for Illinois teachers to enroll in a retirement plan that would transfer with them should they go teach in other states or private schools. A Tier 3 hybrid retirement plan that would have some portability features was announced in 2017, but it has not since been implemented.
