Microsoft Office Specialist (MOS)
Microsoft Office Specialist (MOS) is Microsoft's certification for proven skill in its Office applications. Each exam tests you inside the application itself, on realistic tasks such as formatting long documents in Word, building formulas, charts and tables in Excel, or designing clear, well-structured presentations in PowerPoint. It is widely valued by employers for office, administrative, finance and teaching roles, and by students who want a recognised skills credential.
You can certify in one application or several, and exam numbers depend on the Office version, so we confirm the right exam with you at booking. Our preparation course works through the objectives for Word, Excel and PowerPoint with timed, project-based practice that mirrors the live exam environment, so the format holds no surprises on the day.

Renewal and validity
Microsoft does not set an expiry date on Microsoft Office Specialist certifications. Because each exam is linked to a specific version of Office, many professionals choose to certify again when their workplace moves to a newer version. Check the awarding body's current renewal policy, as arrangements can change.
