Administrative Assistant Cover Letter

An administrative assistant cover letter needs to prove you can keep an office running smoothly — not just list software you know. Hiring managers want evidence of reliability, initiative, and the ability to handle competing priorities without dropping anything.

This guide walks you through what to include, how to structure each paragraph, and gives you a full example to adapt. For a broader overview of letter writing, see our how to write a cover letter guide.

What employers look for in an administrative assistant cover letter

Administrative assistants are the operational backbone of a team. The role covers scheduling, correspondence, document management, travel coordination, vendor communication, and often light bookkeeping.

When reviewing cover letters, employers typically screen for:

• Software fluency — Microsoft Office Suite, Google Workspace, scheduling tools, and any industry-specific systems (EHR, CRM, project management platforms).
• Multitasking under pressure — Can you manage a busy calendar, incoming calls, and last-minute requests at the same time?
• Discretion and professionalism — Administrative assistants handle sensitive information. Employers want confidence that you can be trusted.

Name the tools you use daily and the volume you handle (number of calendars managed, travel bookings per month, documents processed). Specifics separate strong candidates from generic applications.

How to write an administrative assistant cover letter that gets interviews

1) Open with the role and your most relevant skill

State the position, the company name, and one headline capability — for example, the number of executives you support or your experience coordinating cross-department schedules.

2) Show how you keep things organized

Pick one scenario where your organizational skills made a tangible difference: a system you streamlined, a scheduling conflict you resolved, or a process you improved. Include a result.

3) Prove your tech skills in context

Do not just list software. Show how you used it — "Built weekly reporting dashboards in Excel that reduced the team's status meeting from 45 minutes to 15."

4) End with a confident, direct close

Request a specific next step. Keep the closing to two sentences maximum.

Subject: Application for the Administrative assistant position

Dear Hiring Manager, I am applying for the Administrative Assistant position at Whitfield & Partners. With four years of experience supporting teams of up to 12 people across two offices, I bring reliable calendar management, strong written communication, and a track record of improving day-to-day office efficiency. At Redstone Consulting, I manage three executive calendars, coordinate domestic and international travel, and handle all incoming correspondence for the operations department. Last year, I redesigned our filing and document-retrieval system using SharePoint, which cut average search time by 40% and eliminated version-control issues across the team. I am proficient in Microsoft 365, Google Workspace, Concur, and Asana. I am also comfortable onboarding new hires on internal tools and maintaining supply inventories within budget. I take pride in anticipating needs before they become urgent and keeping the office running without bottlenecks. I would welcome the opportunity to discuss how my organizational skills and proactive approach can support your team. I am available for a call at your convenience. Sincerely, [Full Name]

Before you send your application

• Verify the company name, job title, and hiring manager's name if available.
• Include at least one measurable result (time saved, costs reduced, volume handled).
• Remove vague phrases like "excellent communication skills" — replace them with proof.
• Keep the letter to one page. Brevity signals the same efficiency you claim to have.
