Sitting at the top of Microsoft's three-tiered certification pyramid, the Microsoft Certified Solutions Master (MCSM) validates a candidate's knowledge and expertise in designing and building enterprise solutions using Microsoft technologies.
To earn the MCSM certification, candidates should already hold the respective lower-tiered MCSE or MCSD qualification and then pass one or two knowledge-based exams (depending on the specific MCSM track) and complete a hands-on lab exam (approx. 6 hours).

MCSM certification holders are required to take a recertification exam every three years in order to keep their credential active.
