A teacher recommendation letter is a one-page letter from a principal, department head, professor or mentor teacher that supports a candidate applying for a teaching position. Hiring panels read it for evidence of three things: classroom results, classroom management, and how the candidate works with colleagues and parents.
Below are eight samples for different recommenders and teaching roles, a request email script, and the specific details school hiring committees say they look for. Every sample is free to download in Word.
What a school hiring panel is reading for
Teaching is one of the few professions where a candidate is observed doing the job before being hired for it. That means a recommendation letter from someone who has watched the candidate teach carries far more weight than one that speaks only to character.
A strong letter answers five questions:
- Has the writer actually seen this person teach? Formal observations, walkthroughs, or a co-taught class. Say so explicitly, and say how many times.
- What happened to the students? Pass rates, growth scores, attendance, reading levels, exam results. Numbers over adjectives, every time.
- How do they handle a difficult class? Classroom management is the most common reason new teachers fail and the thing panels probe hardest.
- How do they work with adults? Colleagues, department meetings, parent conferences, difficult conversations.
- Would the writer hire them again? Panels look for this sentence. Its absence is noticed.
What weakens a letter:
- Any hedge. A line like “I can’t say you’d be making a mistake if you went elsewhere” reads as withheld endorsement and cancels everything above it.
- Explaining why the writer is not hiring the candidate themselves. It plants a doubt the panel did not have.
- Disclosing the candidate’s family or personal circumstances. That is the candidate’s to share, and in many places it is unlawful for a panel to consider it.
- Praise with no measurement behind it. “Great motivator” is in every letter.
- Running past one page. Panels often read fifty applications in a sitting.
Who should write a teacher recommendation letter
| Recommender | Best for | What they can speak to |
|---|---|---|
| Principal or head teacher | Any teaching post | Formal observations, evaluation ratings, whole-school contribution |
| Department head | Subject-specific roles | Subject knowledge, curriculum work, exam results |
| Cooperating or mentor teacher | First teaching job, newly qualified | Daily classroom practice during student teaching |
| University professor or program supervisor | Graduates with limited experience | Pedagogical training, coursework, teaching philosophy |
| Colleague or co-teacher | Supplementary letter | Collaboration, planning, reliability in a team |
| Instructional coach | Experienced teachers seeking advancement | Response to feedback, growth over time |
Who should not write it: parents of former students, friends, and relatives. Panels discount them. A parent letter can occasionally be attached as a supplement, but never in place of a supervisor.
How to ask for a teacher recommendation letter
Ask three to four weeks ahead, and ask before you need it
Teaching hiring moves in waves, usually heaviest between February and June. If you wait until a specific vacancy is posted, your recommender may be writing five letters that week. Ask at the end of a school year for a letter you will use the following spring.
Ask someone who has observed you teaching
A glowing letter from someone who has never seen you in front of a class is worth less than a measured one from someone who has. If your only option has not observed you, invite them to before they write.
Give your recommender the material
Send a single document with:
- Your résumé and teaching certification or licence details
- The job posting, including the stated requirements for the role
- Your most recent observation or evaluation report
- Two or three specific results you would like mentioned, with the numbers: pass rates, growth data, a programme you started
- The school and panel name, the deadline, and how the letter should be submitted
Tell them if it is for a specific school
A letter addressed to a named principal at a named school outperforms a generic “To Whom It May Concern” letter. If you are applying to six schools, ask for one tailored letter for your first choice and a general version for the rest.
Follow up and thank them
Confirm the letter was submitted, and tell your recommender the outcome. In teaching, where districts and schools are closely connected, this matters more than most people expect.

Sample teacher recommendation letters
1. From a principal (experienced classroom teacher)
[School Letterhead]
[Date]
[Principal Name]
[School Name]
[Address]
Dear [Principal Name],
I am writing to recommend [Teacher Name] for the [subject] teaching position at [School]. I have been principal at [Current School] for nine years, and [Teacher] has taught [subject] here for the past four.
I have formally observed [Teacher] eleven times and dropped into his classroom far more often than that. His [Grade] pass rate on the [exam name] has risen from 68% to 91% over three years, and in the most recent cycle his students outperformed the district average by fourteen points. He achieved this with the same intake as his colleagues, not a selected group.
What I would most want you to know is how he handled [Grade] period four in [year], a class three previous teachers had struggled with. Rather than tightening discipline, he restructured the first ten minutes of every lesson around a written entry task and phoned every parent in the first fortnight. Referrals from that class fell from twenty-two in the first term to three in the second. I have since asked him to lead a session on it for our new staff.
With colleagues he is generous and unshowy. He has mentored two student teachers, both of whom now hold permanent posts, and he runs our Thursday after-school clinic without ever having been asked to.
He is leaving us only because of a relocation. I would hire him again tomorrow without hesitation, and I recommend him to you without reservation. Please call me directly at [phone] or write to [email].
Sincerely,
[Full Name]

2. From a department head (subject-specific role)
[School Letterhead]
[Date]
Dear Hiring Committee,
I head the Science department at [School Name], where [Teacher Name] has taught Biology and AP Environmental Science for three years. I am writing in support of her application for your [position].
[Teacher] took over AP Environmental Science when it had eleven students and a 45% pass rate. It now enrols thirty-four and passed 88% last year. She rebuilt the scheme of work from the specification, introduced a field-sampling unit at [location], and wrote the practical assessment pack that the rest of the department now uses.
Her subject knowledge is genuinely strong. She holds a [degree] in [field] and is the person I send colleagues to when a question goes past the textbook. More usefully, she is good at knowing what students will misunderstand before they misunderstand it, which is a different skill and a rarer one.
In department meetings she disagrees clearly and without friction, and she has taken on the timetabling of our shared lab space, which nobody else volunteered for.
I will be sorry to lose her. She has my strongest recommendation, and I am glad to speak to you directly at [phone] or [email].
Sincerely,
[Full Name]
Head of Science, [School Name]

3. From a cooperating or mentor teacher (first teaching job)
[School Letterhead]
[Date]
Dear Hiring Committee,
I supervised [Candidate Name] during her sixteen-week student teaching placement in my [Grade] classroom at [School Name], from [month] to [month year]. I have hosted student teachers for eleven years and she is among the two or three strongest I have worked with.
She took full responsibility for all five sections by week six, which is ahead of the usual schedule, and I made that decision because she was ready. Her reading intervention group of nine students gained an average of 1.4 grade levels across the placement, measured on the same assessment we use school-wide.
New teachers usually struggle with pacing. She did too, for about three weeks. What mattered is what she did about it: she asked to record one of her own lessons, watched it, and came back with a revised plan that built in a checkpoint every twelve minutes. Her pacing was not an issue again. That response to feedback is the single best predictor I know of how a first-year teacher will do.
She was also the student teacher parents asked for by name at conferences, which in sixteen weeks is unusual.
I recommend her without reservation and would have hired her into my own school if we had a vacancy. Please contact me at [phone] or [email].
Sincerely,
[Full Name]

4. From a university professor (recent graduate, limited experience)
[University Letterhead]
[Date]
Dear Hiring Committee,
I am [Title] in the School of Education at [University], where I taught [Candidate Name] in two methods courses and supervised her final teaching portfolio.
[Candidate] graduated [rank or honours] from a cohort of sixty-one. Her final-placement portfolio was one of four I selected as exemplars for the following year’s cohort, chiefly because of the way she documented differentiation: she included the same lesson planned three ways, with her reasoning for each, and the assessment data that followed.
In my classroom management course she wrote on restorative practice and then, unusually, went and tested it during placement, returning with data on referral rates rather than opinions. I mention this because panels are right to be cautious about candidates with limited classroom time. [Candidate] has less experience than a mid-career applicant. What she has instead is an established habit of measuring whether what she does is working.
She holds [certification] in [subject and grade range] and is eligible for [licence type] in [state or region].
I recommend her warmly and can be reached at [email] or [phone].
Sincerely,
[Full Name], [Credentials]

5. From a colleague or co-teacher
[School Letterhead]
[Date]
Dear Hiring Committee,
I have co-taught with [Teacher Name] for two years in our inclusion [subject] classes at [School Name], where I am the special education teacher of record.
Co-teaching either works or it does not, and it usually does not. Ours worked because [Teacher] treated it as genuine shared planning from the first week. We planned every lesson together for forty-five minutes each Wednesday, and she never once defaulted to the arrangement where the general education teacher teaches and the special education teacher circulates.
Across the two years, our co-taught sections had the highest [subject] pass rate of any section in the building, including the non-inclusion ones. Eighteen of our twenty-two students with IEPs met their [subject] goals last year.
She also handles parent conferences better than almost anyone I have worked with, including difficult ones. I have watched her tell a parent something they did not want to hear and end the meeting with that parent thanking her.
I recommend her strongly, and I say that knowing it means losing her. Please contact me at [phone] or [email].
Sincerely,
[Full Name]
Special Education Teacher, [School Name]

6. For a teacher moving into leadership
[School Letterhead]
[Date]
Dear [Superintendent / Governing Board],
I am writing to support [Teacher Name]’s application for the post of [Assistant Principal / Head of Department] at [School]. She has taught at [Current School] for seven years and has served as [subject] team leader for the last three.
As team leader she manages six teachers, two of them considerably more experienced than she is. When the district changed the [subject] curriculum in [year], she ran the transition for our department: she mapped the old scheme against the new, built a shared resource bank, and ran nine after-school sessions. Our department was the only one in the district to complete the transition within the academic year, and departmental scores did not dip during it, which they did elsewhere.
The part of leadership she has already proved is the difficult part. She has had two hard conversations with underperforming colleagues that I would ordinarily have handled myself. Both teachers are still here and both have improved.
She is ready for this, and I say that as someone who would rather keep her. I recommend her without hesitation and am glad to discuss her candidacy at [phone] or [email].
Sincerely,
[Full Name]
Principal, [Current School]

7. For a substitute teacher applying for a permanent post
[School Letterhead]
[Date]
Dear Hiring Committee,
[Candidate Name] has worked as a substitute teacher at [School Name] for two years and covered a six-month maternity leave in our [subject] department from [month] to [month year]. I am the principal here and am writing in support of her application for a permanent position.
Substitute work is a hard place to judge a teacher from, so let me be specific about the six-month cover, which is the part that counts. She inherited three [Grade] sections mid-year, kept the existing scheme of work rather than restarting it, and her students’ end-of-year results were within two percentage points of the teacher they had lost. Continuity of that kind is unusual for a cover appointment.
Over two years of day-to-day cover she was requested by name by nine different teachers, which is the clearest signal a school has. Our office manager, who sees everything, called her the most reliable substitute on our list.
She holds [certification] and completed [relevant training] in [year].
We would appoint her here if we had a post available. I recommend her without reservation, at [phone] or [email].
Sincerely,
[Full Name]

8. Short letter (when the recommender has limited time)
[School Letterhead]
[Date]
Dear Hiring Committee,
I recommend [Teacher Name] for the [position] at [School] without reservation.
I am [Title] at [School Name], where [Teacher] has taught [subject] for [length of time]. I have formally observed [him/her] [number] times. [His/Her] [Grade] pass rate moved from [X]% to [Y]% over [period], and in [month year] [he/she] [one specific action] which resulted in [concrete outcome].
[He/She] works well with colleagues and parents, and I would hire [him/her] again without hesitation.
Please contact me at [phone] or [email] if it would help.
Sincerely,
[Full Name]

A short letter with three specific facts beats a long one with none. If your recommender is short of time, send them this structure rather than accepting a vague full-length letter.
Five mistakes that sink a teacher recommendation letter
- Hedging the endorsement. Any sentence beginning “I can’t say that…” or “while no teacher is perfect…” reads as a warning. Endorse or decline to write.
- Explaining why the writer is not keeping the candidate. The panel was not wondering. Now they are.
- Mentioning personal or family circumstances. Not the writer’s to share, and in many jurisdictions not lawful for a panel to weigh.
- No evidence of observed teaching. Character references without classroom evidence are the weakest letters a panel receives.
- No contact details. Panels in teaching genuinely do call. A letter with no direct line looks like one that does not want to be checked.
Frequently asked questions
How long should a teacher recommendation letter be?
One page, roughly 350 to 500 words. Hiring panels often review dozens of applications in a single sitting, and letters that run longer are skimmed rather than read.
Who should write a recommendation letter for a teaching job?
A principal, department head, cooperating teacher, or university supervisor who has observed the candidate teaching. Letters from parents, friends or relatives carry very little weight with hiring panels.
How many recommendation letters do teaching applications require?
Most schools and districts ask for two or three. At least one should come from a direct supervisor who has formally observed the candidate in a classroom.
What should a teacher recommendation letter include?
The writer’s role and how long they have known the candidate, evidence from classroom observations, measurable student outcomes, an example of classroom management, and an explicit endorsement with direct contact details.
Can a teacher use an old recommendation letter?
A letter older than two years is generally treated as stale, particularly for a candidate whose practice has changed since. Ask the same recommender for an updated version rather than resubmitting the original.
Should the letter be addressed to a specific school?
Yes, whenever the school is known. A letter addressed to a named principal at a named school signals that the application was prepared deliberately rather than sent in bulk.
Does a teacher recommendation letter need to be on school letterhead?
Yes, where possible. Letterhead lets a panel verify the writer, which matters because most letters are now submitted as uploads through an applicant tracking system rather than as signed originals.
What if a former principal has left the school?
The letter is still valid. Ask them to state their title at the time, the dates they supervised you, and a current contact address, so the panel can still verify the reference.
