Administrative Assistant cover letter example
An administrative assistant’s cover letter has to show that you can handle volume reliably and that you make the office run more smoothly than before you arrived.
Opens with the matching administrative assistant resume, in the same design, so the two read as a set.
The letter, as text
Dear Hiring Manager,
An architecture office runs on deadlines, drawings and a steady stream of calls, and the administrative assistant is the person who keeps all three from colliding. I would like to be that person at Alder & Finch Architects.
For the past four years I have supported busy offices in property management and education. At Cascade Property Management, I support a team of 14 who manage 1,800 rental units, handling scheduling, correspondence, records and invoicing. I answer more than 60 calls and emails a day from tenants, owners and contractors, and I process over 300 vendor invoices a month without a single late-payment penalty since 2023.
I also look for small processes that waste time. Our lease files were all on paper, so I moved them into a shared digital system; finding a document now takes seconds instead of minutes. At Riverside Community College I managed calendars and room bookings for a department of 30 faculty and kept student records accurate and confidential under FERPA, so I am used to handling sensitive information carefully.
I work quickly in Microsoft 365, Google Workspace and QuickBooks, and I type at 65 words per minute. I am available to interview this week and could start within two weeks of an offer.
Kind regards,
Hannah Kim
Why this administrative assistant cover letter works
- The opening describes the employer’s day in plain terms, so the reader can picture the candidate in the job.
- Volume numbers (14 people, 1,800 units, 300 invoices a month) make an everyday role sound as substantial as it really is.
- The digital filing example shows initiative, which is what lifts an admin letter above a list of duties.
- Practical details at the end, typing speed, tools and start date, answer the questions an office manager will have.
Tips for your own administrative assistant cover letter
- Quantify your workload: how many people you support, calls or emails a day, invoices or bookings a month.
- Include one process you improved and what it saved, even if the saving is minutes rather than money.
- Mention any confidentiality rules you have worked under, such as FERPA or HIPAA, because trust is part of the job.
Questions
How long should an administrative assistant cover letter be?
Three or four short paragraphs, about 250 words, never more than one page. Hiring managers skim; every sentence should add proof the resume does not already give.
Do I need a cover letter for an administrative assistant job?
Send one whenever the application allows it, unless the posting says not to. It is your chance to connect your experience to this employer’s needs, and many candidates skip it.
Can I use this cover letter for free?
Yes. Open it in the builder with the matching resume, replace the details with your own, and download both as PDF or Word, free, with no account and no watermark.
