微軟新一代認證體系主要由基礎級別的MCTS認證，中等級別的MCITP和MCPD認證和高端的MCA認證組成，以前MCITP認證和MCPD認證是規定3年的有效期，過期不參加重認證即作廢！現在已經取消取消MCITP和MCPD證書3年有效期的規定！
微軟做出這項改動主要基於以下原因：
1、微軟認為最新的技術對已經成熟
2、這種規定對微軟和微軟的客戶更加簡單；
3、根據各種反饋，希望做出這方面改動。
微軟官方原文：
Dear Microsoft Certified Professional,
We are pleased to inform you about a recent Microsoft Certification policy change that affects your Microsoft Certified IT Professional (MCITP) or Microsoft Certified Professional Developer (MCPD) credential.
In response to customer feedback, Microsoft has eliminated the requirement to recertify, or refresh, your MCITP or MCPD certification every three years. This is good news for you; there is no action required to maintain the certifications you hold today.
