By level, a sensible order is: Professional Administrative Certificate of Excellence (PACE) (entry), then Google Workspace training certificates (entry), then Microsoft Office Specialist (MOS) (associate), then Certified Administrative Professional (CAP) (professional).

Build evidence alongside the exam
Credentials open doors; evidence gets offers. Pair your studying with a project you can discuss in interviews:
- Organise an event with budget, suppliers and schedule.
- Create templates for meetings, travel and onboarding.
- Support a small business owner as a part-time virtual assistant.
- Automate a repetitive admin task with tools such as Zapier.
A realistic study plan
- Week 1: download the official exam outline and take a diagnostic test to find weak areas.
- Weeks 2–5: study one domain at a time and apply each in a lab, exercise or work task.
- Week 6: take timed practice exams and review every wrong answer until you can explain the right one.
- Week 7: revise weak areas, then book the exam while the material is fresh.
Entry and associate exams often fit this schedule. Professional and expert credentials, and licensing exams, usually take months of preparation.
Ask your employer to pay
Many employers fund exams, courses and study time for administrative assistants. Link the credential to your current work and a team goal, propose a timeline, and check whether you would have to repay the cost if you leave within a set period.
Red flags when choosing a provider
- Promises of guaranteed jobs or salaries.
- No clear link to the official issuer or exam outline.
- Course-completion certificates marketed as professional credentials.
- Pressure to buy expensive bundles before you have checked what employers ask for.
How to list certifications on your CV
Use the official credential name, the issuer and the date earned, plus the expiry date where one applies. Label anything in progress clearly ("expected June 2027"). In a administrative assistant cover letter, mention a certification only when it directly supports the role; in interviews, be ready to explain how you have applied what you learned.
