How do you get the Initiate achievement?

I have a rank 12 warframe.. I am not sure exactly what it takes to get to initiate rank.

You have to complete a test. You can see that by clicking escape and looking under your name, is the bar full? If so you can try. Click on profile in the same menu and then there should be "rank up". You can try once a day.

Or you get initiate rank as a daily login reward. (might need to earn ingame anyway, I had that happen)

Ah thanks man.. got it last night. Never noticed the rank up option in the menu!
