I passed my last planned MCPD certification exam on 24 November 2011 (70-519, Pro: Pro: Designing and Developing Web Applications Using Microsoft .NET Framework 4) and became Microsoft Certified Professional Developer.
Also I had an opportunity to become Nokia Qt Certified Specialist on 28 November 2011, I passed 2 exams - 010-002: Qt Essentials and 022-001: Core C++ for Qt developers.
So I can compare some aspects of Nokia Qt and Microsoft Professional Developer certifications.
|Available at least since 1993||Since 2010|
|Score report contains exact received points + information of strength and weak topics, what should be improved||Currently - just Pass or Fail, by forum - might be improved in future|
|Notification from the company is received on the next day (as exam is provided at a special test service partner - might take some time)||The same|
|No paper certificate by default, PDF or XPS can be downloaded from a special MCP site, paper certificate can be ordered for an additional money||Certificate is delivered in 4-6 weeks|
|It is possible to check status anytime on the special site: mcp.microsoft.com, available almost immediately (see 2 rows above)||No any special site, it should be possible to add a special badge to account on developer.qt.nokia.com site by an additional request. For me - request is sent more than 1 week ago, still no any reaction/reply|
|A lot of different exams||Qt without Widgets seems is impossible, despite of QML is a modern way. I hope it will be improved later for Qt5|
So briefly, Nokia Qt Certification is not mature enough, and I hope it will be significantly improved in future.
Anyway preparations for exams helped me to recall some topics and concentrate my knowledge.
So both certification paths - MCPD (MCTS) and Nokia Qt Developer/Specialist are really useful for developers.
