Where can I find the D&D (4th) DM test?

Yes it is nerdy and yes i know women can smell D&D even 20 years later, but i would like to official host D&D meets. I know i don't NEED to take/p the test to host but it was suggested by my former DM. Now my question is where can i find it, YES i have googled it, and YES I’ve tried looking on WOC's home page but i still can't find. please help me.
