A professional-development leave can create a gap in your TRS pension service. In certain circumstances, Texas TRS allows you to purchase service credit for employer-approved developmental leave. But approval of the leave by your employer is not enough: the TRS notice and certification requirements must also be satisfied.
The most time-sensitive step happens before the leave begins. The current TRS 215 form says the completed notice, including the employer's certification, must be received by TRS before your developmental leave starts.
Quick answer: plan before leaving, purchase after qualifying
The developmental-leave provision generally requires at least five years of credited TRS service before the leave and when the purchase deposit is made. Before purchase, you must also have established at least one year of TRS membership service credit after the leave.
The employer must approve a qualifying professional-development purpose, and you must follow the TRS filing requirements. No more than two years of developmental-leave credit can be established under this provision. The cost is actuarial, not a flat administrative fee.
These conditions appear in Government Code Section 823.402 and the current TRS 215 form.
What counts as developmental leave?
TRS describes developmental leave as unpaid leave approved in advance by the TRS-covered employer for study, research, travel, or another purpose intended to improve professional competence. The employer makes the relevant professional-purpose determination.
That does not mean every unpaid absence qualifies. A personal career break, vacation, or ordinary unpaid leave should not be treated as TRS developmental leave without the required employer certification and TRS review.
| Situation | What to establish | What not to assume |
|---|---|---|
| Approved study or research leave | Employer's professional-development approval and required TRS paperwork | Enrollment in a course automatically creates pension credit |
| Travel linked to professional competence | Employer determination and certification of the qualifying purpose | Any travel qualifies because the statute mentions travel |
| Ordinary unpaid personal leave | Ask TRS whether any service-credit provision applies | It automatically falls within developmental leave |
| Unused sick or personal leave at retirement | A different service-credit purchase route | It uses TRS 215 or the same eligibility conditions |
Takeaway: Start with the category of leave. Our unused sick leave service-credit guide addresses accumulated leave at retirement, not a developmental absence from employment.

Eligibility: check each requirement separately
| Requirement | When it matters | Official basis |
|---|---|---|
| At least five years of credited TRS service | Before the leave occurs and when required deposits are paid | Section 823.402 and TRS 215 |
| Employer-approved qualifying purpose | Before the leave | Employer certification on TRS 215 |
| Completed notice and certification received by TRS | Before the leave begins under the current form's instructions | TRS 215 |
| At least one subsequent year of TRS membership service credit | Before the purchase deposit | Section 823.402 and TRS 215 |
| Sufficient qualifying leave period | For the credit being requested | TRS 215 and applicable required-service rules |
| Maximum of two developmental-leave years | Across credit established under this provision | Section 823.402 |
Takeaway: A qualifying purpose does not waive the filing deadline, minimum service, return-to-service requirement, or payment.
TRS 215 states that a leave period must cover at least 90 days during a school year to qualify for purchase of one year, as determined under TRS Rule 25.131 and TRS implementing policies. Have TRS evaluate your actual dates. Do not count any 90 calendar days away from work as an automatic credited year.
TRS 215: why filing before the leave matters
The form is a Notice of Intent to Take Developmental Leave. The member supplies identifying information, approved dates, and the purpose; the employer supplies the required certification.
Section 823.402 requires notice and employer certification on or before the date the leave is taken. The current form is more explicit operationally: it must be received by TRS before the leave begins. Plan around that earlier receipt instruction, not a last-minute mailing date.
The law says the leave is not creditable if the member fails to submit the notice and obtain the required certification. Do not rely on reconstructing the paperwork at retirement.
Keep the completed form and proof of submission. Ask TRS to confirm receipt and whether anything else is needed before departure. A district's approval email and a member's intention to buy credit later do not replace the completed TRS process.
If the leave has already begun and you did not file, contact TRS directly. This guide cannot establish a late-filing exception or promise that the credit can be recovered.
A practical timeline
| Stage | Action | What the stage does not complete |
|---|---|---|
| Before requesting leave | Review existing service and discuss the professional purpose with the employer | TRS eligibility approval |
| Before the start date | Submit completed TRS 215 with employer certification so TRS receives it in time | Payment for pension credit |
| During the leave | Retain approved dates and records supporting the certified purpose | Automatic annual service credit |
| After returning | Establish the required subsequent membership service credit | Automatic approval of a purchase price |
| When eligible to purchase | Request a current TRS cost statement and benefit comparison | A decision that purchase is worthwhile |
| Before retirement | Complete any purchase by the applicable deadline | Permission to ignore a stricter eligibility-related payment deadline |
Takeaway: Notice, qualifying service after return, and payment are separate milestones. Completing one does not complete the others.
For an employment record discrepancy unrelated to developmental leave, ask TRS to identify the correct process. Service that should already have been reported is a different issue from deliberately purchasing credit for an approved unpaid absence.
How much does developmental-leave credit cost?
TRS requires the actuarial present value of the additional standard retirement annuity attributable to the purchased credit, using adopted actuarial rates and tables. There is no universal current price per year.
Do not calculate the cost by multiplying your normal payroll contribution by the months absent. That calculation is not the statutory pricing method for this provision.
Request a current quote when you satisfy the purchase requirements. Ask for the estimated pension with and without the purchase, using the same retirement date and annuity option. Also ask whether the credit changes retirement eligibility in your case.
The TRS purchase chart lists developmental leave separately from other purchase categories. If you also have qualifying prior occupational experience, career and technology teacher work-experience credit is a different provision with different paperwork.
Compare a quote without confusing it with a guaranteed return
Suppose, purely hypothetically, that TRS quotes a purchase cost of $15,000 and a same-date pension estimate shows $150 more per month before tax.
| Hypothetical measure | Calculation | Result |
|---|---|---|
| Additional gross pension per year | $150 × 12 | $1,800 |
| Simple cost divided by annual increase | $15,000 ÷ $1,800 | About 8.33 years |
| Equivalent number of monthly increases | $15,000 ÷ $150 | 100 months |
Takeaway: The example is an initial comparison, not an official quote or an investment return. One hundred months is eight years and four months after the additional pension starts.
The calculation excludes taxes, inflation, money paid years before retirement, alternative investment returns, survivor options, and the possibility that credit changes your retirement date. Use the actual figures from TRS rather than assuming the same increase applies to every member.
Before committing cash, consider your emergency reserve and other retirement expenses. If the purchase affects when you retire, compare complete scenarios instead of dividing cost by a monthly increase alone.
Payment and retirement deadlines
TRS's general purchase guidance states that purchased service must generally be paid by the effective retirement date or the last day of the retirement-application month, whichever is later. If the purchased credit is required for retirement eligibility, payment must be completed by the effective retirement date.
Ask TRS to confirm the applicable payment instructions and deadline on your quote. The later purchase deadline does not undo the earlier requirement to file the notice before leave. For pension processing after employment ends, see the Texas TRS first-payment timeline.
Frequently asked questions
Does all unpaid leave qualify for TRS service credit?
No. Developmental leave has a qualifying professional purpose, employer approval and certification, filing requirements, service requirements, and a purchase cost. Ordinary unpaid leave is not automatically eligible.
When must TRS receive TRS 215?
The current form says TRS must receive the completed form, including employer certification, before developmental leave begins. Submit early enough to meet the receipt requirement.
Can I file after returning from leave?
Do not assume that is allowed. The law requires notice and certification tied to the start of leave, and the current form requires receipt before the leave begins. Contact TRS if you missed that step.
Must I return to TRS-covered work before buying the credit?
The provision requires at least one year of TRS membership service credit after the developmental leave before the required deposits are paid.
How many developmental-leave years can I purchase?
No more than two years can be established under this provision, and the leave periods and other requirements must qualify.
Are the cost and pension increase in this article official rates?
No. The $15,000 cost and $150 monthly increase are hypothetical comparison inputs. TRS must provide an individual cost statement and benefit estimates.
