T-TESS 2 Timeline - What Texas Districts Do and When

The T-TESS 2 rollout runs across three school years. Fifteen school systems pilot the refreshed rubric in 2026-27, appraiser recertification training begins in spring and summer 2027, 2027-28 is the recommended adoption year, and 2028-29 is the implementation year for districts that cannot move in 2027-28. If your district is not in the pilot, nothing about T-TESS 2 is required of you this year.

Most Texas district leaders are looking for confirmation that T-TESS 2 requires nothing of them in 2026-27, and that confirmation is buried three paragraphs into a TEA letter. This post lays out the rollout year by year, then works through the decision that actually remains open: whether to adopt in 2027-28 or wait a year. For what changes inside the rubric itself, start with T-TESS 1 vs T-TESS 2.

What Is the T-TESS 2 Rollout Timeline?

The Texas Education Agency has published the schedule in administrator correspondence rather than a single planning document. Here it is in one place.

1. 2025-26. Field testing, complete. TEA tested draft rubric language with school leaders and teachers across multiple districts and surveyed both groups on clarity and coverage.
2. 2026-27. Pilot year. Fifteen school systems use T-TESS 2 in live appraisal contexts. Every other Texas district continues on the current 16-dimension rubric.
3. Spring and summer 2027. Appraiser recertification training begins. TEA has stated that more information on training will be available in fall 2026.
4. 2027-28. Recommended implementation year. This is TEA's target year for districts adopting T-TESS 2.
5. 2028-29. Implementation year for districts unable to implement in 2027-28. There is no year after this one in TEA's published plan.

Read those last two items together, because they are routinely misread as a menu. They are not. 2027-28 is when TEA wants you on the refreshed rubric, and 2028-29 is the accommodation for districts that cannot get there. A district on the state-recommended system does not have a 2029-30 option.

Can My District Still Join the T-TESS 2 Pilot?

No. TEA opened pilot recruitment through a February 12, 2026 administrator letter with an interest survey deadline of March 5, 2026, and confirmed the selected cohort in a June 2026 follow-up. The 15 systems are set for 2026-27, and there is no published second cohort or mid-year entry path.

TEA has not published the names of the 15 participating school systems. If you encounter a specific district list attributed to the pilot, check it against a TEA document before you plan around it, because the agency's own correspondence names a count and not a roster.

What the pilot is evaluating is public, and it tells you what the refreshed rubric is being held to: whether it clearly defines effective teaching across different school contexts, whether it supports appraiser calibration, whether it aligns with district priorities, and whether it functions operationally in a real appraisal cycle. Those four questions are a reasonable checklist for your own readiness review in 2027, pilot or not.

Should Your District Adopt T-TESS 2 in 2027-28 or Wait Until 2028-29?

This is the live decision, and it is closer than the "recommended" label suggests. Most districts should probably plan for 2027-28, but the case for waiting is real and worth stating honestly.

Four things argue for adopting in 2027-28.

1. Recertification training is already sequenced for it. Appraiser training runs spring and summer 2027. If you adopt that fall, your appraisers apply the rubric within months of learning it. Wait a year and you have trained people who then spend a full year appraising on the old rubric before using the new one.
2. You inherit a full year of pilot findings. TEA refines the rubric during 2026-27. A 2027-28 adopter gets the refined version with implementation guidance already shaped by 15 districts' experience.
3. Your first T-TESS 2 year is a low-stakes year. Ratings under an unfamiliar rubric are noisy. Better to absorb that noise in the recommended year, when your regional service center and neighboring districts are working through the same problems, than in the year you are the last one figuring it out.
4. One transition, not two. Every crosswalk, evidence template, and appraiser handbook gets rebuilt once.

Four argue for waiting until 2028-29.

1. Appraiser turnover is a real cost. If you train an appraisal team in summer 2027 and lose a third of it by summer 2028, you are paying for training twice regardless. Districts with high assistant principal churn may get more out of training closer to implementation.
2. The 2027-28 school year is already loaded. The STAAR replacement assessment for grades 3-8 arrives in 2027-28. Stacking a rubric transition on top of an assessment transition is a genuine capacity question, not an excuse.
3. Implementation guidance keeps improving. Documentation, exemplars, and calibration materials will be materially better in 2028 than in 2027.
4. Ratings tied to compensation raise the stakes. In districts where appraisal outcomes feed Teacher Incentive Allotment designations, a first-year rubric transition has consequences beyond the write-up. That is an argument for moving when your appraisers are most confident, not when the calendar says to.

The honest summary: if your appraisal team is stable and your 2027-28 calendar has room, adopt in 2027-28. If you are rebuilding an appraisal team or absorbing a major assessment change at the same time, 2028-29 is a legitimate choice and TEA built it into the plan for exactly this reason. What is not legitimate is arriving at 2028-29 by default because nobody made the call.

When Does T-TESS 2 Appraiser Recertification Training Happen?

Spring and summer 2027, per TEA, with details promised in fall 2026. That sequencing creates a scheduling problem worth naming now: spring is when most campuses are closing out summative conferences and end-of-year appraisal paperwork. Asking the same assistant principals to attend recertification during their heaviest appraisal weeks is how training attendance quietly becomes a compliance exercise.

Two things help. Put a placeholder on the 2027 professional development calendar this fall, before other priorities claim those dates. And separate the budget line for recalibration from the one for recertification. Recertification training teaches your appraisers the new rubric. It does not make them agree with each other about what Proficient looks like under it, and calibration is the work that actually protects rating consistency.

What Did T-TESS 2 Field Testing Actually Find?

TEA's 2025-26 field test surveyed both school leaders and teachers on the draft rubric, and the results reported in July 2026 were unusually strong on clarity.

• 100% of surveyed school leaders and 97% of surveyed teachers agreed the performance levels were clear.
• 96% of leaders and 90% of teachers said the rubric captures the essential aspects of teaching.

Those numbers measure whether people understood the rubric, which is not the same as whether appraisers using it independently arrive at the same rating. Clarity is a precondition for calibration, not a substitute for it. Treat the field-test results as evidence that the rubric language is better, and plan your calibration work as though nothing has been solved for you.

What Should Non-Pilot Districts Do in 2026-27?

Nothing is required. These five moves cost little now and make the transition year cheaper, whichever year you pick.

1. Confirm your current rubric in writing before the first formal observation. Which version a teacher was appraised on is the kind of detail that only becomes contested at a grievance hearing.
2. Stop building 16-dimension artifacts. Any evidence template, crosswalk, or cheat sheet you rebuild this year is scrap once the 12-dimension list publishes.
3. Start capturing frequency evidence. T-TESS 2 asks that a target practice generally be demonstrated at least 80% of the time to meet a performance level descriptor. Notes that record how often something happened, not just that it happened, transfer directly to the new rubric.
4. Budget recalibration separately from recertification. They are different line items solving different problems, and the second one is the one that gets cut.
5. Watch for TEA's fall 2026 training guidance. The agency has committed to publishing more detail this fall. That is your first real planning input for the 2027-28 versus 2028-29 decision.

Your 2026-27 observation cycle should still be built on the current rubric. The refresh changes what you prepare for, not what you appraise on this year. For districts running the numbers on appraiser capacity across multiple campuses, the district view of observation activity is usually where the transition-year staffing question gets answered.

Observation Copilot supports the current T-TESS rubric natively, organizing raw observation notes by domain and dimension and mapping evidence to the five-point scale. Principals across Texas use it to get from notes to a structured draft the same day.

Observation Copilot has allowed me an opportunity to provide feedback to the teachers within the same day versus 24 to 48 hours. Being able to have access to the tool gives me very specific feedback and it just makes it an easier process for me.

Same-day feedback matters more in a transition year, not less. When appraisers are working with unfamiliar rubric language, the gap between the lesson and the write-up is where evidence gets lost and default ratings creep in.

Frequently Asked Questions

When is T-TESS 2 required?

TEA recommends implementation in 2027-28 and names 2028-29 as the implementation year for districts unable to move in 2027-28. There is no later option in TEA's published plan. Districts may still adopt a locally developed appraisal system under Texas Education Code 21.352 instead of the state-recommended one.

Which districts are piloting T-TESS 2 in 2026-27?

TEA has confirmed that 15 school systems were selected for the 2026-27 pilot but has not published their names. Any specific district list circulating without a TEA source should be treated as unverified. The pilot tests rubric clarity, appraiser calibration, alignment with district priorities, and operational fit.

Can my district still join the T-TESS 2 pilot?

No. Recruitment opened in February 2026 and the cohort was confirmed in June 2026. TEA has not announced a second cohort or a mid-year entry path. Districts outside the pilot continue on the current 16-dimension T-TESS rubric through 2026-27 and adopt T-TESS 2 in 2027-28 or 2028-29.

When does T-TESS 2 appraiser recertification training happen?

Appraiser recertification training begins in spring and summer 2027. TEA has stated that more detail will be available in fall 2026. Districts should reserve 2027 professional development dates now, since spring overlaps with summative conference season on most campuses.

What major changes will be implemented in Texas education in 2026?

For appraisal specifically, 2026-27 is the T-TESS 2 pilot year, with 15 school systems testing the refreshed rubric. Broader changes taking effect include the launch of Education Freedom Accounts and a new personal finance graduation requirement for incoming ninth graders. The Texas Association of School Boards tracks appraisal-specific updates as TEA publishes them.
