What is the recertification policy for the MCITP certification?

Where as the old Microsoft exams would expire if you did not sit a “refresh” exam within three years, the MCITP does not expire on the same policy. The new MCITP credential only expires when Microsoft ends their mainstream support of that particular technology. For instance, if you get certified as a MCITP:Server Administrator in Windows Server 2008, your certification will remain valid until Microsoft stops mainstream support for Server 2008, which is planned for 2013. In saying that, just becuase the MCITP credential expires, it does not mean it is worthless, it still reflects your level of knowledge with that technology, which most likely has a large over-lap with the new technology.
