Supporting a senior leader is a different job from supporting a team. You're guarding a single person's time, speaking in their name, and seeing things most of the company never does. Learn the calendar and inbox mechanics first, then the meeting prep that proves your judgment, and save the budget and chief of staff skills for once you're in the seat.
| Certificate | Best for | Effort | Worth it? |
|---|---|---|---|
| Certified Administrative Professional (CAP) | Working assistants who want a recognised credential for senior EA roles | A few months of evening study | The best known certificate in this field, run by the International Association of Administrative Professionals. It helps on a résumé, but a strong reference from an executive you supported counts for more. |
| Microsoft Office Specialist (MOS) Expert | Assistants whose résumé doesn't prove advanced Excel, Word or PowerPoint | A few weekends per exam | Worth it if you're coming from a role with little desk work. Once you've supported a senior leader, hiring managers stop asking for it. |
| Certified Meeting Professional (CMP) | EAs whose job leans heavily on offsites, conferences and board retreats | Several months, and it requires event experience before you can sit the exam | Only worth it if events are a big part of the seat. For most executive assistants it's overkill, but it can open doors toward events or chief of staff work. |
Eligibility rules, fees and exam formats change, so check with each certificate provider before you register.
Supported the CEO with scheduling, travel and other tasks.
Ran the CEO's calendar, inbox and travel across 4 time zones, prepared packets for 6 board meetings a year in Diligent, and cleared a 90-day backlog of Concur expenses in 3 weeks.
An administrative assistant usually supports a team and a shared office. An executive assistant supports a senior leader and acts for them, so the skills lean toward judgment: speaking in their voice, protecting their time, and handling board and confidential material.
Not to get hired, but it helps a lot for roles supporting a CEO or a company with an active board. Diligent Boards and BoardEffect are common. If you haven't used one, learn the basics of how packets are built and permissions are set.
Yes, once your calendar and inbox skills are solid. Smartsheet, Asana and Monday.com come up often in senior EA and chief of staff postings, because the job grows into tracking other people's work, not just your executive's.
Rarely. Some legal and traditional finance offices still like fast, accurate typing for dictation. Most executives care more that your notes capture decisions and owners than how quickly you took them.
