Teaching is one of the few professions where defined benefit pensions still dominate, but the systems that fund those pensions vary dramatically by state. California teachers have CalSTRS. Texas teachers have TRS. New York teachers have NYSTRS. Each works differently, funds differently, and offers different options at retirement. What they share: most do not allow lump sums, and most do not pay into Social Security, which until January 2025 meant WEP and GPO reduced whatever Social Security teachers had earned from other jobs.
The major TRS systems
CalSTRS (California). The second-largest public pension in the country. Formula: 2.0% per year under the 2% at 60 benefit structure for pre-2013 members, or 2.0% at 62 for PEPRA members. A teacher with 30 years earns 60% of final average salary. No lump sum option. Five-year vesting.
Texas TRS. Formula: 2.3% times years of service times average of 5 highest annual salaries. A 30-year teacher earns 69% of final average salary. Texas TRS offers a Partial Lump Sum Option (PLSO) at retirement, allowing members to elect 12, 24, or 36 months of benefit as a one-time payment in exchange for a permanently reduced monthly annuity. Five-year vesting.
Illinois TRS. Formula: 2.2% for first 10 years, 2.66% for years 11-20, 3.11% for years 21-30, 3.55% for years above 30. Strongly rewards long-career teachers. No lump sum. Ten-year vesting for Tier 2 members hired after January 1, 2011.
NYSTRS (New York). Formula varies by tier. Tier 6 members hired after April 1, 2012: 1.75% per year for 20 years, then 2.0% per year above 20. Ten-year vesting. No lump sum option, but service credit purchase options are available.
Georgia TRS. Formula: 2.0% times years of service times average of highest 2 consecutive years. Ten-year vesting. No lump sum. One of the better-funded teacher systems in the Southeast.
The WEP repeal and what it means for teachers
About 15 states have teacher pension systems where teachers do not pay Social Security taxes during their teaching career. Before January 2025, these teachers faced the Windfall Elimination Provision (WEP) if they had Social Security credits from other work, and the Government Pension Offset (GPO) if they had spousal or survivor SS benefits.
The Social Security Fairness Act, signed January 5, 2025, repealed both. Teachers who worked in SS-covered jobs before or after their teaching career now receive their full earned SS benefit. Spouses of teachers who lost spousal SS benefits to GPO now receive those benefits. If you have not seen your SS amount updated, check your my Social Security account and contact SSA if the reduction is still showing.
Survivor benefit options
Most TRS systems offer joint and survivor annuity options at retirement. The reduction varies but is typically 5 to 15% of the monthly benefit to add a 100% survivor benefit for a spouse. Teachers in states without Social Security should pay particular attention to survivor benefit elections. Their spouse may have limited SS income from the teacher's career. The survivor benefit election at pension retirement may be the primary guaranteed income source the surviving spouse has.
Pension funding across state teacher systems
Teacher pension systems vary widely in funded status, and that affects long-term benefit security for active teachers still accruing benefits. According to the National Association of State Retirement Administrators (NASRA), the median funded ratio for state public pension systems is approximately 74%, but individual teacher systems diverge significantly from that figure.
Illinois TRS is funded at roughly 44%, one of the lowest ratios in the country. The underfunding accumulated over decades of inadequate state contributions. New Jersey TPAF is similarly strained at around 38% funded. By contrast, Wisconsin's pension system maintains full funding and South Dakota Teachers are above 100% funded. California's CalSTRS improved from approximately 61% in 2016 to over 76% by 2024 after a dedicated funding increase. Texas TRS is approximately 75% funded. Funded status does not affect current retirees' benefits, which are constitutionally protected in most states. But it does affect future contribution requirements and the risk of benefit reductions for current active members in states without constitutional protections.
Part-time teachers and substitute teachers
Most state TRS systems require a minimum number of hours or days worked per year to earn pension service credit. Part-time teachers typically earn prorated credit. Substitutes often face higher thresholds: some systems require a substitute to be assigned to a position for a full semester before any service credit accrues at all.
Texas TRS requires one-half or more of a full school year to earn credit. Illinois TRS allows substitutes who work at least 600 hours in a school year to earn prorated credit. NYSTRS requires 11 or more days per month to earn credit for that month. Teachers who spent years in part-time or substitute roles before moving to full-time positions sometimes discover that their credited service years are substantially less than their calendar years in the classroom. Request a service credit history from your plan administrator if there is any uncertainty about your credited years.
Moving between states: reciprocity agreements
Most state teacher pension systems have no portability. If you teach in California for 8 years, leave for Texas, and teach there for another 15, you have two separate pension benefits from two separate systems rather than one combined benefit. CalSTRS and Texas TRS are not reciprocal systems.
A small number of states have bilateral reciprocity agreements that allow service in one state to count toward vesting in another. Georgia has agreements with several southeastern states. But these agreements are the exception. For teachers who move across state lines mid-career, the more useful option is typically a service credit purchase: if you leave a state system before vesting, you can sometimes transfer your contributions to the new state's system and purchase equivalent credit. Costs and eligibility conditions vary, and the purchase must usually be made within a specific window after joining the new system.
Teacher pension versus 403(b): what the research shows
A career teacher who reaches full retirement eligibility typically accumulates more guaranteed retirement income from a defined benefit pension than from a 403(b) alone. The Teacher Pension Project at the Fordham Institute analyzed benefit levels across states and found that a teacher who earns a full career in one state receives a median replacement rate of approximately 70% of final salary, well above what most 403(b) savers achieve. But the same analysis found that a teacher who leaves after 12 years, before the peak benefit years, walks away with substantially less than a 403(b) saver who contributed at the same rate throughout. Pension wealth in most teacher systems is highly backloaded: the bulk of lifetime pension value accrues in the final 5 to 10 years before retirement eligibility.
Disability retirement for teachers
Every state TRS system has a disability retirement option, but the terms differ substantially. Most require a minimum number of years of credited service before disability benefits are available: CalSTRS requires 5 years, Texas TRS requires 10 years, NYSTRS requires 10 years for most members. The benefit is typically a percentage of final salary, often 50 to 60%, paid as a lifetime annuity. Some systems pay the earned accrued pension if it is higher than the disability benefit floor.
Teachers who become disabled before meeting the service threshold may receive only a refund of their own contributions rather than a lifetime benefit. If you are nearing a service threshold and have a health condition that could affect your ability to work, understanding your disability benefit eligibility is worth doing before a potential forced separation from employment.
Supplementing TRS with a 403(b)
Most teacher pension systems allow participants to contribute to a 403(b) supplemental retirement account through payroll deduction. 403(b) plans are the nonprofit and government sector equivalent of the private-sector 401(k). Contribution limits for 2026 are $24,500 per year, with a $7,500 catch-up for employees 50 and older. Teachers in states with strong pension systems often underuse 403(b) plans because the pension feels sufficient. But teachers who leave before reaching full retirement eligibility, or who want inflation protection beyond what a fixed pension provides, benefit from supplemental savings.
The 403(b) is particularly useful for teachers in non-Social Security states who entered the system mid-career with limited SS credits. Even after the WEP repeal improved SS benefits for these teachers, 403(b) savings provide investment-driven growth and estate value that the pension does not. Teachers within 10 years of retirement should review their 403(b) contribution rate alongside their pension projection, especially if their TRS system has no COLA or a below-inflation adjustment.
What teachers should do in the 10 years before retirement
The decade before TRS retirement is when planning decisions have the most impact. The benefits of acting early compound, and the costs of waiting until the final year are significant.
10 to 7 years out: Maximize service credit. If you have prior public service eligible for purchase, including substitute teaching, out-of-state public employment, or military service, get the purchase cost estimate from your TRS system now. Actuarial purchase costs increase significantly as you approach retirement age. A 45-year-old purchasing 3 years of prior service credit pays meaningfully less than a 55-year-old purchasing the same 3 years. For teachers within 3 years of a Rule of 80 or Rule of 85 threshold, the service credit purchase typically pays back within 3 to 5 years of retirement through the higher monthly benefit.
7 to 5 years out: Model your benefit at multiple retirement dates. Most TRS systems provide online benefit estimators. Run projections at the nearest unreduced retirement age and at 2 and 4 years early. The difference between retiring 3 years early versus at the unreduced age can be $400 to $800 per month for life. For a teacher with a $3,200/month unreduced pension, a 10% early reduction is $320/month less for 25 to 30 years of retirement, totaling $96,000 to $115,000 in foregone income. Make the decision with that number explicit.
5 years out: Attend your TRS pre-retirement workshop if offered. Texas TRS, Illinois TRS, CalSTRS, and most large state systems offer free in-person or virtual pre-retirement seminars covering benefit options, survivor elections, health insurance, and the application process. These sessions answer questions that are difficult to resolve by reading the handbook alone. Register at 5 years out, not in the final month before retirement.
3 years out: Verify your Social Security earnings record at ssa.gov/myaccount. With the WEP repeal effective January 2025, SS credits earned from non-teaching work count in full. Know your SS benefit before modeling total retirement income. A teacher with a $2,800/month TRS pension and an $850/month SS benefit has a different income picture than one with no SS credits. Request a formal benefit estimate letter from your TRS system. Verify that your salary history and service credit in the system are accurate. Errors in salary records happen and are significantly harder to correct after separation from employment.
1 year out: Begin the formal pre-retirement application process. TRS processing times range from 30 to 90 days. Submit your application at least 60 days before your intended retirement date. Make your survivor benefit election affirmatively. The survivor benefit choice in a TRS plan is often irrevocable at retirement. Do not let it default.
The 30-year teacher's total retirement income picture
Most TRS retirement discussions focus on the pension in isolation. The full picture includes TRS pension, Social Security (if applicable), 403(b) savings, and any part-time income in the early retirement years. For a career teacher with 30 years of service in a state with an average TRS benefit structure, the numbers are materially better than most teachers expect.
Example: A 30-year Texas TRS teacher retiring at the Rule of 80 threshold (age 55 with 30 years, or age 60 with 20 years, depending on tier). Final salary $72,000. TRS benefit: 2.3% times 30 times $72,000 = $49,680/year ($4,140/month). Texas TRS members generally do not pay Social Security during their TRS employment, but under the WEP repeal effective January 2025, any SS earned from non-Texas employment now counts in full. A teacher who worked 8 years in a Social Security-covered job before teaching may have a Social Security benefit of $800 to $1,100/month at 62. Combined with TRS: $4,940 to $5,240/month.
If that teacher also contributed to a 403(b) at a modest rate throughout their career -- 5% of salary on a $60,000 average salary for 30 years with 6% average annual returns -- the 403(b) account would be approximately $420,000 at retirement. Drawing 4% annually provides an additional $16,800/year ($1,400/month).
Total monthly retirement income: $4,140 TRS pension plus $1,000 SS (assumed) plus $1,400 from 403(b) = $6,540/month in the first year of retirement, before any COLA adjustments. For a teacher who spent their career earning a public-sector salary, that income picture compares favorably to most private-sector workers' retirement outcomes. The pension is the foundation; the 403(b) provides the inflation buffer and estate value that the fixed pension does not.
Key questions to ask your TRS system before retirement
Most TRS systems have a pre-retirement counseling service that allows members to ask specific questions before submitting their application. Use it. Specific questions worth asking: What is my final average salary calculation using the years XXXX through XXXX? Does my service credit include the substitute year I worked in 2009, and how was it calculated? What survivor benefit options are available to me and what is the monthly cost of each? If I retire on a date in the middle of a school year, how does that affect my final average salary calculation? Can I retire and return to part-time work in a non-TRS-covered position without affecting my pension?
Get answers in writing, or at minimum document the date, time, and name of the representative you spoke with. Phone counseling conversations are not legally binding, but a written record of what you were told creates a basis for a formal claim if the benefit you receive differs from what you were promised. Errors in TRS benefit calculations do occur. The most common: incorrect service credit totals, missing years due to leave periods, and salary history errors from years where your employer reported incorrectly. Identifying these before your retirement date gives you the opportunity to correct them through normal administrative channels. The appeals process after a benefit has been incorrectly set can take 6 to 12 months. Catching the error at the estimate stage takes a phone call. Treat the pre-retirement estimate review as a required step, not an optional one. Every TRS system provides this service at no cost to the member. Use it every year in the five years before your planned retirement date, not just once at the end.
PBGC coverage and public pension protection: why TRS is different
Private-sector pensions are insured by the Pension Benefit Guaranty Corporation, a federal agency that steps in when a corporate pension plan fails due to employer bankruptcy or underfunding. Public-sector pensions -- including every state TRS system -- are not covered by PBGC. State law and, in many states, constitutional provisions provide the protection instead.
In most states, accrued public pension benefits are treated as a contractual right that cannot be reduced retroactively for already-earned service. Courts in New York, Illinois, California, and others have consistently ruled that pension benefits for already-accrued service are legally protected and cannot be cut without triggering constitutional obligations. Illinois provides the strongest protection: Article XIII, Section 5 of the Illinois Constitution explicitly states that membership in a state pension system is an enforceable contractual relationship, and that benefits shall not be diminished or impaired. Illinois courts have upheld this protection repeatedly against legislative attempts to reduce pension costs.
Texas TRS, CalSTRS, NYSLRS, and most other large state systems are similarly protected, though the specific legal basis varies. In states without explicit constitutional pension protection, benefit security depends more heavily on the plan's funding level and the political will to maintain contributions. The National Education Association and state teacher unions actively monitor and litigate against proposed benefit reductions, providing an additional layer of protection through collective action.
What this means practically: for active TRS members, the risk of benefit reduction on already-accrued service is low in most states -- significantly lower than the risk of a private-sector pension plan failing and being taken over by PBGC with benefit cuts. The PBGC guarantee in 2026 is $7,789.77/month. TRS benefits have no analogous cap. A teacher with 38 years of service entitled to a $6,500/month benefit is owed that full amount by state law, not subject to any federal guarantee ceiling.
What happens to your TRS benefit if you leave teaching before retirement
Teachers who leave TRS-covered employment before reaching retirement eligibility have options that vary significantly by state and years of service. Understanding these options before leaving is essential; the decision made at separation is often irrevocable.
The refund option: most TRS systems allow departing members to take a refund of their employee contributions, sometimes with credited interest. Taking a refund forfeits all accrued pension rights permanently. A teacher who contributed $85,000 over 12 years and takes a refund gives up a $1,200/month deferred pension at age 62 in exchange for the $85,000 plus interest. At a 5% discount rate, the present value of $1,200/month starting at 62 for a 35-year-old departing teacher is approximately $125,000 to $145,000 -- substantially more than the refund amount. For members with 10 or more years of service, leaving the money in the system and collecting the deferred pension produces greater lifetime value than taking the refund in the large majority of cases.
The deferred vested option: most TRS systems allow members with vested service (typically 5 to 10 years depending on the state) to leave their contributions in the system and collect a deferred pension at the normal retirement age. This preserves the most value for members who leave teaching mid-career. The benefit is calculated at the formula and salary in effect at the date of separation, not at the future retirement date -- so there is no salary growth benefit after leaving, and no COLA accrual until payments begin in most systems.
Reciprocity between TRS systems: some states have reciprocity agreements that allow teachers to combine service from multiple states for retirement eligibility purposes, even if the monthly benefit is calculated separately by each system. California, Oregon, and Washington have reciprocity agreements with each other and with other western states. Texas TRS does not participate in multi-state reciprocity. Illinois TRS has limited reciprocity with other Illinois public retirement systems but not out-of-state systems. Verify with your specific state TRS system before assuming reciprocity applies to your situation. Many states have online lookup tools or member service hotlines specifically for reciprocity questions. A 15-minute call confirming reciprocity eligibility before accepting a teaching position in another state can protect years of pension accumulation that would otherwise be separated into two smaller, potentially non-qualifying accounts.
The decade-by-decade TRS planning summary
TRS members who approach retirement systematically -- verifying service credit in their 40s, modeling benefit scenarios in their early 50s, attending pre-retirement workshops at 5 years out, and submitting a complete application at least 60 days early -- consistently report smoother transitions and fewer post-retirement benefit corrections than members who wait until the final year to start planning.
The most common preventable mistakes: taking a refund of contributions after leaving a position and permanently forfeiting a deferred pension, missing a service credit purchase window when the actuarial cost was still favorable, defaulting on the survivor benefit election without modeling the true cost of each option, and submitting a retirement application with errors in the final average salary period that take months to correct.
None of these mistakes requires extraordinary planning to avoid. They require knowing what questions to ask and when to ask them. TRS systems are not adversarial -- they want to pay you correctly. The members who get exactly the benefit they earned are the ones who verified their records, corrected errors before submission, and used the free pre-retirement counseling services their system provides. Every step in the process is documented in your system's member handbook. Reading it once, 5 years before your planned retirement date, is the most valuable hour of retirement planning you can do. Every TRS system publishes a member handbook that covers benefit formulas, service credit rules, survivor options, early retirement penalties, refund procedures, and the application process in detail. Most systems also offer a secure online portal where members can view their current service credit, salary history, and projected benefit at multiple retirement ages. Using these tools regularly -- not just in the final year -- is the difference between a retirement that works exactly as planned and one that requires correcting errors under time pressure. Log in to your TRS member portal at least once per year, confirm your service credit total is accurate, and save the statement. An annual five-minute check is the lowest-cost retirement planning habit that exists.
Use the present value calculator to frame your TRS pension as a financial asset in present value terms before the retirement election is filed -- most teachers are surprised how large the number is. Use the Social Security calculator to model claiming timing if your state allows Social Security participation alongside TRS. Use the pension income tax calculator to understand your state's treatment of pension income and whether a retirement location decision affects your after-tax income materially. TRS pensions are among the most generous in public employment. Claim yours correctly.
