A free part time cover letter that states the hours and then stops discussing them
One part time cover letter, printed exactly as the builder wrote it: sender block, date, recipient, subject, four paragraphs and a sign-off. The assistant and the school are invented. The letter, the tracing and the one gap came out of the product.
— twenty hours is a fact, not an apology.

Part time applications often spend half their length on the hours, which is the one thing the advertisement already settled. Lorcan Whitbourne is invented, Halberry Primary School is invented, and so are both of his schools.
Lorcan Whitbourne and Halberry Primary School are invented, and so are the employers in the evidence; the letter below is the builder's own output from that evidence, unchanged.

Re: Teaching Assistant, 20 hours
Dear Halberry Primary School Hiring Team,
I'm applying for the Teaching Assistant, 20 hours role at Halberry Primary School. Teaching assistant with four years in primary classrooms, working part time around a caring commitment at home. You ask for Safeguarding, and that is work I have already done: Led safeguarding reporting for the playground rota and raised 2 concerns correctly.
I have worked as Teaching Assistant at Ferncroft National School, 2022 — present. I have also worked as Learning Support Assistant at Maryhill Primary, 2020 — 2022. I trained 2 new assistants on the phonics scheme and the reading record. I also delivered one to one support for 3 children with special educational needs.
I supported a class of 28 children in Key Stage 1 four mornings a week. The posting asks for Safeguarding, Phonics and Special Educational Needs — all of which I've worked with directly. The posting also asks for Recruitment, which I have not used in these roles.
I would welcome the opportunity to discuss the role. Thank you for considering my application.
Sincerely,
Lorcan Whitbourne
The hours are stated and then left alone. They stand in the subject line and in the opening sentence because they are part of the role title, and once more in the profile sentence, working part time around a caring commitment at home. Every other sentence is about the work, which is the right proportion.
How every letter on these pages is built from its evidence is set out in how our examples are made.
Opening lines for a part time cover letter
Three ways to start it:
“I'm applying for the 20-hour Teaching Assistant role at Halberry Primary School, and my availability matches your hours.”
“Your posting asks for reading support, which I have given in two primary schools.”
“I would bring steady support to your classes within the hours you need.”
Set these beside the opening the free letter builder writes from what you give it.
Mistakes that sink a part time cover letter
The first is leaving availability unclear. The second is treating the role as less serious because it is part time. The third is ignoring the school's own priorities.
State your hours early, then evidence. The length guide keeps it short.
What it refused to claim
One gap came back: recruitment. Classroom support and lunchtime cover are named in the advertisement and are outside the matcher's vocabulary, so neither could have been reported either way. Read the advertisement yourself and make sure the evidence list answers what the machine cannot see.
Phonics was in that same blind spot on 12 September and was added the next day, along with the Early Years Foundation Stage, the key person approach, the progress check, paediatric first aid and the Prevent duty, which is why phonics now stands in the fit sentence. The honest limits of every tool covers the distinction.
What a part time letter has to prove
The same things a full time one proves, at the same level of detail. A class of 28 in Key Stage 1, one to one support for 3 children with special educational needs, 2 concerns raised correctly, 2 assistants trained on the phonics scheme. Nobody reading that is thinking about the hours.
State the reason once, plainly, in a clause, and then let it go. The product has a field for anything only you can say, and it is used exactly as written. Care work and unpaid experience covers the surrounding history.

Use this exampleSee the letter designsQuestions
- Is Lorcan Whitbourne a real person
- No. He is invented for this page, and so are Halberry Primary School, Ferncroft National School and Maryhill Primary. No real child or setting is described, and no hire is claimed.
- Did the product really write this letter
- Yes. The evidence list on this page was loaded through this page's own door, the company city was typed into the field 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: four requirements read in the posting, 17 evidence lines offered, seven sentences traced to a numbered line of them, ten written from named connective patterns, one gap, no model.
- Should a part time application explain why the hours are part time
- One clause in the profile line is enough, as here. The letter then spends its space on the work. A hiring manager advertising 20 hours has already decided that part time is acceptable.
- Does an empty gaps list mean everything was covered
- The list is not empty here: recruitment came back as the one gap, out of four requirements the engine read. Classroom support and lunchtime cover are named in the posting and are not in the matcher's vocabulary, so read the advertisement yourself as well. Phonics was in that same blind spot on 12 September and was added the next day, which is why it is now in the fit sentence.
- 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. The contact name, their title and the company city stay empty for you to fill. No letter and no application record exists until you press Create new draft.
- Which design is this example in
- Minimal, air and restraint. Any of the 12 designs carries the same words. Minimal is also the letter design these pages pair with the Minimal résumé layout, and that pairing is authored here rather than built into the builder.
Conxfolio is a free set of four career tools: a résumé builder with 37 rendered layouts, an ATS résumé checker that prints its own arithmetic, a cover letter builder that traces every proof paragraph back to the line it came from, and a portfolio builder with 22 authored designs. There is no account to create, nothing is held back for a paid plan, and no language model is used anywhere in the product, so the readers, the score and the letter are deterministic code you can check.
