How to write it
Duties are not evidence — volume is
"Managed executive calendars" is on every administrative assistant resume ever written, including the ones from people who managed one calendar with four meetings a week. It carries no information because it does not distinguish anyone.
"Manage four executive calendars averaging 35–45 meetings a week, including standing prioritisation calls when commitments conflict" describes a specific workload and a specific kind of judgement. The reader now knows the scale you operate at and that you are trusted to arbitrate between competing demands, which is the actual skill.
Every duty on your list has a number attached to it somewhere. How many people, how many meetings, how many trips, how large a budget, how many invoices, how many events, how many new hires. Find them and put them in. This single pass does more for an administrative resume than any other change.
- People supported, and their level
- Meetings coordinated per week, and how many calendars
- Trips booked per year, and the travel budget
- Events run, and attendee counts
- Invoices, expenses or purchase orders processed per month
- The size of any budget you were accountable for
Name the systems
Administrative work runs on software, and the products are specific enough that experience with the right one is a genuine hiring advantage. Concur, Navan, Expensify, Coupa, Workday, NetSuite, Salesforce, Asana, Monday, Confluence, Egnyte, DocuSign — an employer running one of these would rather not spend three weeks training you on it.
This is also the part of your resume that a keyword search will actually match on. "Proficient in Microsoft Office" is assumed and matches nothing useful; "Microsoft 365, Google Workspace, Concur, Coupa, Asana, DocuSign" is a list of terms a recruiter is plausibly searching for.
Be specific about depth where it matters. If you administer the tool rather than use it — you are the one who sets up approval chains in Coupa, or manages the Workspace org — say so, because that is a different and more valuable capability.
Show judgement, not just execution
The difference between an administrative assistant and a good one is decision-making, and it is the hardest thing to convey in a bullet. Execution is booking the trip. Judgement is knowing which of two conflicting meetings the VP should actually attend, catching that a vendor contract auto-renews next month, or rescheduling a week before an executive realises they need to.
Write those. "Standing prioritisation calls when commitments conflict" says you are trusted to make the call. "Flagged a vendor auto-renewal that saved a $22k charge for a service the team had stopped using" is judgement with a number on it.
The same applies to anything you improved. An administrative assistant who rebuilt a broken expense process, wrote the onboarding checklist the department now uses, or created the template that halved document turnaround has done work above the job description — and that is the evidence that gets someone hired into a more senior role rather than a lateral one.
Discretion and confidentiality
Anyone supporting executives handles material that is not public: compensation, performance, org changes, acquisitions, legal matters. Employers know this and screen for it, and most candidates leave it entirely implicit.
State it, carefully. "Handle confidential material including compensation cycles, org changes and two acquisitions under NDA" tells a reader you have operated at that level of trust without disclosing anything. What you must not do is name the acquisition, the figures or the people — a resume that demonstrates discretion by breaching it is self-defeating, and readers notice.
The same restraint applies in interviews, and stating it on the page sets up the right expectation.
Titles, and the executive assistant question
Administrative assistant, executive assistant, office administrator, administrative coordinator and office manager overlap enormously and are used inconsistently between organisations. What matters is scope, not the title you held.
So describe the scope plainly and let the reader map it. Someone supporting a C-suite executive at a 40-person company may be doing more than an "executive assistant" at a large corporation who supports one director. If your title understated your role, do not inflate it — instead put the scope in the first bullet, where it does the same work honestly.
If you are aiming for a step up into executive support or a chief of staff track, say so in the summary. It reframes the whole page as a trajectory rather than a lateral application.
