Certification is not required for employment. However, the U.S. Department of Labor states, "[Job] opportunities should be best for applicants with extensive knowledge of computer software applications." The Career Step Executive Assistant program prepares you for the Microsoft Office Specialist Master credential with training on either Microsoft Office 2010 or 2007 software applications. Earning the MOS Master credential will prove your knowledge of software applications and increase your job opportunities and earning potential, and a free exam voucher to take a Microsoft Office Specialist exam is included with the course upon graduation (a $120 value).
