It took me a couple of days to get my results back, and another week or so to get the wavier.

However, don't make the same mistake I made...keep copies of your test results and wavier. I lost mine somewhere along the way and somehow I became un-certified in their system (long story). So now I'm in the middle of having to get re-certified all over. So yeah, keep copies of ALL of your paperwork in case you end up in the same boat as me.
