According to the MS Certification Guidance Team, the MCDST is expiring 3/31 instead of 6/31.
Here's the email that I got from them:
"I’m sorry, but there currently is a discrepancy on the website regarding the retirement date and unfortunately, we do not have a resolution at this time. Therefore, you will need to complete the MCDST exams 70-271 and 70-272 before March 31, 2011."
This drastically changes my exam schedule, but I just wanted to pass it along to everyone!
For what it's worth, here's the
link to the current retirement schedule.
