Hi,
Microsoft does provide a tool to help organizations track training for groups of individuals. Here is the link:
http://www.microsoftlearningplans.com/SignIn.aspxI saw a demonstration of this and was pretty impressed with what I saw but I have not used this tool myself. The tool was originally created for Microsoft partners but I believe that any group can use it. You will need a Windows Live ID (hotmail, MSN account, etc.) to sign in.
Good luck!
