This means that any other exam in most cases will no longer give you entry level certification. Microsoft Certified Professional (MCP) is now a community only and you will still get a MCP ID when you pass the first exam. You can share your transcript with others to prove that you passed that exam and show your progress towards a specific certification.

If you currently hold an MCP Cert, is it possible to transfer that to a MTA?
