Performance review tips

Performance Review Tips for Teachers

The teacher reviews that hold up six months later are the ones grounded in evidence beyond the single observation. The ones that don't tend to fail in predictable ways. Tips split by audience, with shared ones at the end.

Teacher performance reviews are one of the few documents in education that get written once a year and read by exactly two people. The teacher being reviewed, and the reviewer’s line manager during the next round of calibration. That’s a small audience, but both audiences are unusually critical readers, and the review either earns their respect or quietly loses it. The tips below are about earning it.

Three sections: tactics for school leaders writing reviews, tactics for teachers writing self-evaluations, and the moves both sides should get right. For the underlying framework, see how to write a performance review for a teacher.

Tips for school leaders writing reviews

1. Schedule walkthroughs, not just observations

Two formal observations a year doesn’t produce enough evidence to write a confident review. Aim for one short walkthrough per teacher per fortnight (4 to 5 minutes is enough). The cumulative signal is far more useful than two carefully-prepared formal observations, because what you’re seeing is the teaching as it actually is on a normal Wednesday.

2. Read the cohort context before the data

Before pulling end-of-year results, pull the September baseline, the SEND register, the EAL proportion, and the attendance pattern. The data only means something with the cohort attached. A 58% pass rate against a 75% target reads as a clear miss without context; with a starting baseline of 41% and eight students on EHC plans, it’s a different story. The cohort context isn’t an excuse; it’s the unit of analysis.

3. Calibrate against the strongest teacher you’ve ever supervised

Rating inflation is the slow-motion failure mode of teacher review systems. Once a few colleagues are rated “outstanding,” the next round drifts upward. After three or four cycles, half the staff are outstanding and the tier means nothing. The fix: calibrate against the strongest teacher you’ve ever managed, not against your current staff average. The teachers who deserve the top rating want it to carry weight.

4. Don’t deliver new feedback at review time

If a teacher is hearing a piece of feedback for the first time in writing at the end of the year, the cadence of conversation has slipped. The review should formalise things you’ve been saying in observations, post-observation conversations, and catch-ups across the year. Surprises in review season damage trust in the whole process.

5. Name colleague input deliberately

A 10-minute conversation with the subject lead, the head of year, or the teaching assistant who works closely with the class will tell you things no observation will. The point isn’t to gossip; it’s to triangulate. Patterns that show up across three or four colleagues are real signal. Single comments are noise.

6. Make the development priority specific

“Continue to develop higher-order questioning” is a non-priority. “Lead a peer-observation cycle on higher-order questioning across the key stage in the autumn term, with observation pairs reading the same sequence and comparing notes after each lesson” is a priority. The strong reviews end with one thing the teacher will actually do that you and they can both check on in October.

Tips for teachers writing self-evaluations

7. Build your evidence inventory in June

The single biggest mistake teachers make is writing the self-evaluation in the last week of term, alongside end-of-year reports and the planning for September. Forty-five minutes in early June, pulling cohort data with context, naming the units you’re proudest of, and writing down one thing that didn’t work, gives you the raw material for the actual writing. See the prep step in teacher self-evaluation examples for the full list.

8. Lead with growth from baseline

Your headline data is the cohort’s endpoint score. The story is the growth from the starting position. If your class came in 8 months below expected and finished 4 months above, that’s the opening-paragraph fact. Endpoint scores alone get flattened by calibration committees against easier-cohort comparators; growth-from-baseline doesn’t.

9. Name one specific unit that didn’t land

On the “what didn’t go well” prompt, pick a real unit and tell the structural story. Not “I’d like to improve differentiation,” which evidences nothing. “The autumn persuasive- writing unit fell short because I under-estimated the modelled-writing baseline the cohort needed, and I’ve already redesigned it for September,” which evidences strong professional judgement. Teachers who write self-aware misses with named fixes consistently come across as more developed practitioners.

10. Surface the work that won’t show in your data

The parent workshop you ran, the colleague you mentored through their first difficult parent conversation, the scheme of work you redesigned for the team. These don’t show up in your cohort outcomes but they’re force-multiplier contributions that distinguish strong teachers from competent ones. If you did this work and didn’t write it into your self-evaluation, the calibration room doesn’t see it.

11. Frame goals as concrete changes, not abstractions

“Improve my classroom management” is a non-goal. “Adopt the silent transition routine I observed in Sarah’s class for the start and end of lessons across the autumn term” is a goal. Each goal you set should name a specific change in practice, a measurable outcome, and a deadline you and your head can both check on at a 1:1.

12. Pull your last review out before drafting

Last year’s feedback and your own goals from last year are the calibration baseline for this self-evaluation. If you set three goals last year and only mention one this year, you’re effectively letting your reviewer bring the other two up. Better to surface them yourself, including the ones that didn’t fully land. Self-awareness about your own development arc reads as strong professionalism.

Tips for both sides

13. Have a pre-review conversation

Two weeks before the formal review meeting, schedule 30 minutes to compare notes. The point isn’t to align documents; it’s to surface disconnects on the headline narrative. If you both think the defining work of the year was the reading restructure, great. If the reviewer thinks it was the reading restructure and the teacher thinks it was the parent-workshop programme, you want that conversation before the documents are written.

14. Treat the review as the start of next year, not the end of this one

The most important conversation is the one after the document is signed. Agree on two or three specific things to do differently in the autumn. Write them down somewhere both of you will see again in September. Return to them in the early-term 1:1. A review that doesn’t change practice was paperwork, and the autumn 1:1 is where the change actually starts.

15. Acknowledge the cohort honestly

Both sides should name the cohort context for the year explicitly. The 41% starting baseline. The SEND register. The attendance pattern. The mid-year admissions. These shape what was possible, and leaving them implicit in the review is one of the most common ways calibration outcomes go sideways twelve months later when the cohort is forgotten and the headline number is the only thing on the record.

The shape of a teacher review that ages well

Twelve months from now, read the review and ask whether you could picture the cohort and the year it was written about. The strong reviews pass. They have specific units named, specific observation moments, specific cohort context, specific development priorities. The weak reviews don’t. They could have been written about any teacher in any year at any school, which means they’ll be treated that way at the next round of calibration.

Everything in this article is in service of that test. The rest of the cluster covers the underlying framework, the worked examples, and the teacher-side counterpart:

Frequently asked questions

What's the most important performance review tip for teachers?

If you're a school leader: schedule short walkthroughs every fortnight instead of relying on two formal observations a year. The cumulative evidence is fundamentally better than the prepared lesson. If you're a teacher: build your evidence inventory in early June, lead the self-evaluation with growth-from-baseline rather than endpoint scores, and name one specific unit that didn't land with the redesign you've already made. Both habits do more for review quality than any other single change.

How should a school leader prepare for a teacher performance review?

Block 90 minutes per teacher across two sittings if possible. The first 45 minutes is evidence collection: pulling cohort data with context, re-reading every formal observation note, reviewing the teacher's planning artefacts, having brief conversations with two or three colleagues who work closely with the teacher. The second 45 minutes is drafting. Reviews written from memory without that evidence base tend to read as generic; reviews built from a wider evidence base read as specific.

How do I avoid rating inflation in teacher performance reviews?

Calibrate against the strongest teacher you've ever supervised, not against your current staff average. Hold a calibration session with other school leaders before reviews are finalised, where you talk through your tentative ratings and what evidence supports each. The teachers who deserve the top rating want it to carry weight; protecting the meaning of the rating is part of protecting your strong teachers.

Should student feedback be used in teacher performance reviews?

Aggregated student-voice signal, yes. Structured surveys, focus groups run by someone other than the class teacher, departmental cohort data on engagement and progress. Individual student complaints are pastoral matters and don't belong in a review document. The pattern across the cohort is the useful signal; single voices are not.

When should I deliver feedback to a teacher about their performance?

Continuously, in observation debriefs and in your regular catch-ups. The performance review document should be a summary of conversations you've already had, not the first time you've named a pattern. If something genuinely new is showing up in a year-end review, the cadence of mid-year conversation isn't working and that's the underlying thing to address before the next review cycle.
