Ok as I heard today, you need to have made several configurations, send them in and philips will grade your configuration. If they rate it high enough you will be granted level 3!
I'm gonna call my distri tomorrow (they do know about level 3) and I'll take the test. Hope to be a certified level 3 installer soon :)
I'll let you all know how it works (hence me replying on an old thread)
