Is there a Microsoft certification for InfoPath?
Microsoft does not have a certified master program specifically for InfoPath. http://www.microsoft.com/learning/mcp/certifications.mspx
Qdabra Software (the company that hosts this site) does offer a Master Training Course for InfoPath. http://www.qdabra.com/en/training/InfoPath_Master_Class.aspx
Microsoft has recently expressed an interest in working with Qdabra to offer online training.
