Administrative Assistant Job Description: Duties, Skills, and Responsibilities

What an Administrative Assistant Does

An administrative assistant keeps the operational side of a team, department, or office running so that everyone else can focus on their own work. In practice that means owning the calendar, the inbox traffic that does not need a manager's attention, the documents and records people depend on, the logistics of meetings and travel, and the small physical and vendor details of the office itself. The best administrative assistants do this quietly: when the role is done well, problems are resolved before anyone notices them, and the people they support simply find that things work.

Job postings tend to list twenty duties in no particular order. It is more useful to group the work into six areas. Almost every administrative assistant role is some mix of these, weighted differently depending on the employer.

Core Duties and Responsibilities

1. Calendar and scheduling

• Maintain one or more calendars. Book, move, and decline meetings; protect focus time; keep recurring meetings current.
• Coordinate across people and time zones. Find workable slots for internal and external attendees without endless email back-and-forth.
• Resolve conflicts. Decide (or escalate) which commitment wins when two collide, based on priorities you have agreed in advance.
• Prepare people for what is next. Attach agendas, dial-in details, and context so that nobody walks into a meeting cold.

Scheduling is the most visible part of the job and the one where small errors are most expensive. If you support more than one person, the rules change; see supporting multiple executives.

2. Communication and front-line contact

• Answer and route calls and emails. Handle what you can, forward what you cannot, and keep a record of what came in.
• Draft routine correspondence. Confirmations, reminders, follow-ups, polite declines, and announcements.
• Act as first point of contact. Greet visitors, field inquiries, and represent the team professionally to clients, vendors, and other departments.
• Manage a shared or delegated inbox where the role calls for it, with clear rules about what you send and what you only draft.

3. Documents and records

• Create and format documents. Letters, memos, reports, presentations, and forms that look consistent and are free of errors.
• Maintain filing systems. Physical and digital, with naming conventions people can actually follow.
• Enter and update data. Contact lists, trackers, spreadsheets, CRM or HR system records.
• Handle confidential information correctly. Know what is sensitive, who may see it, and how long it must be kept.

4. Meetings

• Plan logistics. Rooms, video links, catering, equipment, and materials.
• Distribute agendas and pre-reads early enough to be read.
• Take minutes and track action items. Capture decisions and owners, circulate notes promptly, and follow up on what is overdue. The meeting minutes templates cover the common formats.

5. Travel and expenses

• Book travel within policy. Flights, hotels, ground transport, and itineraries that include confirmation numbers and contacts.
• Handle changes and disruptions. Rebook quickly when plans move.
• Process expense reports and reimbursements. Collect receipts, code expenses correctly, and submit on time.
• Track small budgets. Petty cash, team events, supply spend.

6. Office operations

• Order and track supplies. Keep inventory without overstocking.
• Coordinate with vendors and facilities. Cleaning, maintenance, equipment repairs, deliveries.
• Support onboarding. Desks, equipment, access badges, and first-day logistics for new hires.
• Organize team events. From a birthday lunch to an offsite.

In smaller organizations this area can grow into most of the job. Office and facilities management covers it in depth.

Skills an Administrative Assistant Needs

Hard skills

• Office software. Working fluency in Microsoft 365 or Google Workspace: Word/Docs formatting, Excel/Sheets basics (sorting, filtering, simple formulas, and ideally lookups and pivot tables), and Outlook/Gmail calendar features.
• Collaboration tools. Teams, Slack, Zoom, and whatever project or ticketing tool the team uses.
• Written communication. Clear, correct, appropriately toned emails and documents. This matters more than typing speed.
• Scheduling and time-zone handling. Booking across regions without mistakes.
• Record-keeping and data accuracy. Entering information once, correctly, in the right place.
• Basic bookkeeping. Expense coding, invoice tracking, and reconciliation at a simple level.

Soft skills

• Prioritization. Knowing which of ten requests actually needs doing first.
• Discretion. Handling salaries, personnel issues, and leadership plans without leaking them, even casually. See confidentiality and discretion.
• Anticipation. Noticing what someone will need before they ask.
• Composure. Staying calm and polite when the calendar collapses or a caller is angry.
• Reliability. Doing what you said, when you said, every time. Trust in this role is built almost entirely on follow-through.
• Judgment about when to escalate. Handling what is yours to handle and flagging what is not, early.

How the Role Differs by Setting

The title is the same across industries, but the work is not. Before applying, or before writing a posting, be clear about which version you mean.

• Corporate. Often supports a department or several managers. Heavy on scheduling, meetings, travel, and expenses, with established systems and policies to follow.
• Legal. Document-heavy, deadline-driven, and precise. Court filing deadlines, document formatting standards, client confidentiality, and billing records. Legal-specific roles are often titled legal secretary or legal administrative assistant.
• Medical. Patient-facing. Appointment scheduling, intake, insurance verification, medical records, and strict privacy rules (such as HIPAA in the United States). Medical terminology is usually expected.
• School and education. Front-office work with students, parents, and staff: attendance, enrollment records, communications home, and plenty of interruptions. Rhythm follows the academic calendar.
• Small business. The broadest version of the role. One person may handle reception, bookkeeping support, purchasing, HR paperwork, and the website. Less structure, more variety, more trust.

Administrative Assistant vs. Related Roles

• Executive assistant. Supports one senior leader (or a small leadership group) closely, with more delegated authority, more confidential access, and more decisions made on that person's behalf. Many admins move into EA roles after a few years. For the step beyond that, see chief of staff vs. executive assistant.
• Office manager. Owns the office as an operation: budgets, vendors, facilities, sometimes HR administration and supervision of other support staff. An administrative assistant may report to an office manager.
• Receptionist. Focused on the front desk: greeting visitors, answering phones, and managing deliveries. An administrative assistant usually does some of this, plus the scheduling, document, and coordination work behind it.

Titles are inconsistent between employers. Read the duties, not the title, to tell which job you are actually looking at.

Sample Administrative Assistant Job Description

Employers can adapt the template below. Replace the bracketed placeholders, delete duties that do not apply, and be honest about the balance of the work. A posting that describes the real job attracts candidates who will stay.

A note on pay: ranges vary widely by region, industry, and seniority, so we do not publish a single number here. Check the U.S. Bureau of Labor Statistics Occupational Outlook Handbook and current local postings, and see our salary guide for how to think about it.

Using a Job Description to Tailor Your Resume

If you are applying rather than hiring, the posting is the most useful document you have. Use it deliberately.

1. Mark the top three duties. The first few bullets, and anything repeated, are what the hiring manager cares about most. Your resume should prove those three first.
2. Mirror the language honestly. If the posting says "calendar management for multiple managers" and you did that, use those words. Applicant tracking systems and human screeners both look for the match. Never claim tools or duties you have not done.
3. Add scale and outcomes. "Managed calendars for four directors across three time zones" says far more than "managed calendars." Numbers you can verify are better than adjectives.
4. Match the setting. For a legal role, lead with document accuracy and deadlines; for a medical role, patient contact and privacy; for a small business, range and self-direction.
5. Prepare stories for each core duty. Interviewers will ask for examples. Have one short, specific story ready for scheduling, a difficult person, a mistake you fixed, and a confidential situation.

The resume guide covers structure and action verbs, and the interview preparation guide covers the questions you are most likely to face. Once you land the job, your first 90 days lays out how to settle in.
