Dear Principal [Last Name],
I am writing to apply for the High School Biology Teacher position at [School Name]. I am a state-certified science teacher with five years of experience teaching general and AP Biology, and my classroom is built on a simple conviction: students work hardest for teachers who make the subject feel like it belongs to them.
At [Current School], I redesigned the biology curriculum around inquiry - fewer lectures, more investigations students design themselves. The results have followed. AP Biology enrollment has doubled since I took over the program, and last year 78 percent of my students earned a 3 or higher, up from 54 percent three years ago. The change I am proudest of is quieter: students who used to describe themselves as bad at science are staying for the elective sequence.
Beyond my own classroom, I sponsor the science club, coach our Science Olympiad team to its first regional finals appearance, and mentor a first-year teacher through our district induction program. I grade with rubrics students see before they start, call home with good news as often as concerns, and treat classroom management as relationship-building done early rather than discipline done late.
I am drawn to [School Name] because of its project-based learning initiative. That is the direction I have been pushing my own practice, and I would arrive ready to contribute lessons, lab designs, and assessment tools I have already tested with real classes.
Thank you for considering my application. I would welcome the opportunity to teach a demonstration lesson.
Sincerely,
[Your Name]
Run your finished letter through these checks before you send it.
It opens to a named principal with a stated subject
Addressing Principal by last name, applying for the biology position, and stating state certification across five years of general and AP Biology tells an administrator this letter was written for one school.
The results are stated as movement, not levels
Seventy-eight percent of students earning a 3 or higher, up from 54 percent three years earlier, and AP enrollment doubling since taking the program over show growth an administrator can attribute to the teacher rather than the intake.
A quieter outcome balances the numbers
Students who used to call themselves bad at science staying for the elective sequence is the result no score report captures, and it tells a principal what the room actually feels like.
The method is specific enough to be evaluated
Rubrics students see before they start, calls home with good news as often as concerns, and management framed as relationship-building done early rather than discipline done late are practices an administrator can picture during an observation.
Change the subject and the certification to yours
Write the exact certification area on your license, the state that issued it, and any endorsement the posting asks for. English, math, and history letters need their own evidence, not borrowed biology results.
Use the data your school actually collected
AP scores fit an AP course. Elsewhere use state assessment growth, course pass rates, reading levels, credit recovery, or attendance in your sections. With no numbers at all, describe the change in student work instead.
Name a real initiative at that school
Project-based learning is the hook here. Read the school improvement plan, the course catalog, or the principal's newsletter, then connect one specific program to something you have already built and can bring with you.
Adjust the extracurricular paragraph to their needs
Postings and school pages often reveal which coaching or club vacancies exist. If you can take one, say so. Schools staff a whole building, and a willing sponsor is a genuine advantage in a close decision.
Writing to a district instead of a school
"Dear Hiring Committee" with no school named reads as a mass application in a pool where personalization is the first filter. Find the principal's name on the school site or call the front office and ask.
Describing philosophy without a classroom in it
Every teaching letter believes in every student. The paragraph earns its place only when it shows what the belief looks like on a Tuesday: the task, the grouping, the feedback, and the follow-up.
Leaving certification status ambiguous
State certification rules differ and administrators screen on them first. Say what you hold, in which state, and whether an out-of-state license is already in process, rather than leaving the office to check.
Ignoring the job outside the classroom
Duty coverage, department meetings, data teams, clubs, and family communication fill a teacher's week. A letter that mentions none of it reads like someone who has only ever taught in a student teaching placement.
Use the ones that are true of you, in the sentences where you describe the work - not as a list bolted to the end. Matching a job description's vocabulary helps a keyword filter find you; it is not what convinces the person who reads the letter afterwards.
How long should a high school teacher cover letter be?
One page, four paragraphs, roughly 300 to 400 words. Administrators read stacks of these during hiring season, so use the first paragraph for certification, subject, and years, the middle for evidence, and the last for this specific school. A second page rarely survives the first cut.
How do I write this letter for a district I am moving to?
Say where you are certified, whether you have applied for reciprocity, and when you expect to be cleared to teach. Certification transfer rules vary by state, so check the receiving state board rather than assuming. Then explain the move in one honest sentence, because principals ask about it anyway.
Should I include test scores and student data?
Include them when they are yours and you can explain them: growth over a baseline, pass rates in your own sections, enrollment changes in a course you built. Always report the starting point as well as the result, because data with no baseline invites the assumption that you inherited a strong group.
What should a first-year teacher write?
Use your student teaching placement as the classroom: the school, the grade levels, the units you planned and taught, and one lesson that did not work along with what you changed. Add your certification area and any club or sport you could sponsor, since new hires are often chosen on what else they cover.
