Replying to PSIA Membership & Certification ?????

I was wondering if anyone here happens to be a PSIA member and if anyone for that matter is certified. Next year when i move out to colorado getting my PSIA certification is the first thing im going to do. I have read the website, but it doesnt seem to make to much sense. In order to become a ski instructor must i take their courses and be certified for each level??? If somebody could post the details, how its done, how long it takes etc..... that would be awesome.

Peace,
Colin
