Essential Information

Certification in Microsoft Office, called the Microsoft Office Specialist (MOS) certification, demonstrates proficiency and expertise in using the software. An MOS certification applies to a specific version of Microsoft Office and an associated software program (e.g., MOS in Word 2010 is distinct from certification in Outlook 2007). The three levels of certification include the basic MOS, the MOS Expert and the MOS Master. Certification candidates must successfully pass computerized examinations that take up to an hour and a half to complete.


There are no formal prerequisites for taking the certification exam; however, Microsoft generally advises that candidates have experience using Office and spend at least 20 hours studying for it. Microsoft provides information on exam preparation resources at

Employment Outlook

Microsoft Office is widely used by businesses and organizations to perform technological tasks such as managing email, storing and accessing data, performing financial analyses and creating presentations. At businesses and organizations using Office, most employees will work with at least one of its programs.

Applicants and employees with expertise in Microsoft Office typically require less training and use its software with greater efficiency than those without it. While such an advantage does not guarantee employment or career success, MOS certification can differentiate a candidate competing for a job or promotion.
