Is Ottoline Bray a real person

No. She is invented for this page, and so are Cottersmoor Academy, Calderhaye School and Rosemoor High. No real teacher's application is published here and no outcome is claimed for it.

Did the product really write this letter

Yes. The evidence list on this page was loaded through this page's own door, the optional contact name, title and school city were typed into the fields Details & drafting asks for, and Write the letter was pressed. The reply is printed above unchanged, blocks and all. The engine reports its own provenance: six requirements read in the posting, seventeen evidence lines offered, seven sentences traced to a numbered line of them, ten written from named connective patterns, two gaps, no model.

Why is safeguarding a gap when every teacher is trained in it

Because this document does not say so. The engine reads the evidence in front of it and nothing else, and a plausible assumption is still an assumption. Special educational needs came back as the second gap for the same reason. One true line in the evidence list closes a gap and the letter can then use it. Six requirements were read in this posting, and that count is printed beside the gaps so an empty list can never be read as a clean sweep.

What does “Use this example” do

It opens the cover letter builder in Details & drafting with the role, the school, the posting and the four evidence groups already loaded. Three optional fields stay empty for you to fill: the contact's name, their title and the school's city. No letter and no application record exists until you press Create new draft.

Should a teaching letter name the school

Yes, and the engine puts it in the salutation and the opening for you as soon as the company field is filled. A letter addressed to nobody is the most common thing we see in a first draft, and it is free to fix.

Which design is this example in

Editorial, a serif-led dateline. It is paired here with the Bridge résumé layout the matching teacher résumé example uses. That pairing is authored on these pages rather than built into the product, and the builder still opens whichever of the 12 letter designs you choose. Each of them carries the same words.

A free teacher cover letter built from results, and the two duties it would not claim

One secondary teacher cover letter, printed exactly as the builder wrote it: sender block, date, recipient, subject, four paragraphs and a sign-off. The teacher and the school are invented. The letter, the tracing and the gaps came out of the product.

The finished cover letter in the letter builder in the Editorial design: sender block, date, recipient block, subject line, salutation, four paragraphs and a sign-off — The letter this page quotes, on the letter builder in the Editorial design. The picture was taken by pressing this page's own door, typing the optional fields Details & drafting asks for, and pressing Create new draft.

A teaching application is read by someone who has fifty of them. This page shows what a letter can carry that survives that reading. Ottoline Bray is invented, Cottersmoor Academy is invented, and so are both schools in her history. The letter is real work: the evidence below was loaded into the cover letter builder through this page's own door, and the whole business letter that came back is printed here word for word.

Ottoline Bray and Cottersmoor Academy are invented, and so are the employers in the evidence; the letter below is the builder's own output from that evidence, unchanged.

The post, and the evidence the letter may use

An invented person. Not a real document, and not yours.

Re: Teacher of Mathematics

Dear Mr Adrian Follbrook,

I'm applying for the Teacher of Mathematics role at Cottersmoor Academy. Mathematics teacher with seven years in secondary schools, working on the gap between what a class can do and what the assessment asks of them. You ask for Classroom Management, and that is work I have already done: Trained 3 early career teachers through their first year of behaviour management.

I have worked as Teacher of Mathematics at Calderhaye School, 2019 — present. I have also worked as Teacher of Mathematics at Rosemoor High, 2017 — 2019. I taught 5 classes a week across Key Stage 3 and GCSE, 148 pupils in total. I also improved the GCSE grade 4 pass rate in my classes from 61% to 78% over three years.

I led the department's assessment and data tracking for 420 pupils. The posting asks for Classroom Management, which I've worked with directly. The posting also asks for Special Educational Needs and Safeguarding, which I have not used in these roles.

I would welcome the opportunity to discuss the role. Thank you for considering my application.

Sincerely,
Ottoline Bray

How every letter on these pages is built from its evidence is set out in how our examples are made.

The Conxfolio cover letter builder on Details & drafting, opened by this page's own door, with the role Teacher of Mathematics, the company Cottersmoor Academy, the posting and the four evidence groups loaded — Details & drafting holding Ottoline Bray's evidence for this teacher post.

Opening lines for a teacher cover letter

Three ways to start it:
“I'm applying for the Teacher of Mathematics post at Cottersmoor Academy, having taught maths to Key Stages 3 and 4 since 2017.”
“Your department's focus on closing gaps in Year 9 matches the intervention I ran last year, which moved most of the group up a grade.”
“I would like to bring my experience of running a maths club and mentoring trainees to your school.”

Put your own number in, or let the free cover letter builder propose one from your lines.

Mistakes that sink a teacher cover letter

The first is a statement of teaching philosophy with no class, cohort or result attached. The second is naming every initiative in your current school without saying what you did in it. The third is ignoring the school's own priorities, which are usually in the job pack.

Read the job pack, answer two of its priorities with evidence, and keep the letter to a page. The structure guide shows the four paragraphs.

What it refused to claim

Two gaps came back: special educational needs and safeguarding. Both are named in the posting and neither appears anywhere in Ottoline's evidence, so the letter claims neither and says so in one plain sentence. Every secondary teacher in the country has safeguarding training, and the letter still will not say she does, because the document does not. The gap is printed for her to answer with a true line. The rule behind that refusal is the whole design of this engine.

No language model is used anywhere in it.

What a teacher's letter has to prove

Duties are assumed. Every applicant plans lessons, marks books and sits with a form group, so a paragraph listing those says nothing a head of department did not already know. What has to appear is an outcome with a number on it and a mechanism beside it: the pass rate with the teaching that moved it, the data tracking with the number of pupils it covered, the early career teachers with what they were taken through.

The second thing is the phase. Key Stage 3 and GCSE are named in the first line of her evidence, because a mathematics department hiring for Key Stage 3 does not want to guess. Outcome lines for teachers works through more of these.
