Microsoft certification exam # 074-100 (MSF Practitioner Exam) is retiring, July 28th and is being replaced by exam # 070-301.
For those MCTs who want to continue to deliver MSF courses, such as Course 1846A, after December 31, 2004, they will be required to pass 070-301 in addition to becoming an MCT with MSF Competency.
As a side note, Microsoft has said that MSF 4.0 exam plans will be announced in the Visual Studio 2005 release timeframe, mid 2005.
