Microsoft Office Certification Update:

The Microsoft Office Specialist (MOS) certification now extends to all versions of Microsoft Office, including the 2007 Microsoft Office System and Microsoft Office 2010, as well as Windows desktop operating systems. Instead of using different certification names for different versions of Microsoft Office programs and Windows desktop operating systems, Microsoft has updated all of the Microsoft Office certifications to have the same name—Microsoft Office Specialist (MOS). This applies to all certifications for Microsoft Office versions, including Microsoft Office 2000, Office XP, Office 2003, the 2007 Microsoft Office System, and Microsoft Office 2010. It also applies to all Windows desktop operating system certifications for Windows Vista and Windows 7. The certifications for the 2007 Microsoft Office System are no longer referred to as Microsoft Certified Application Specialist (MCAS) certifications.
