I was told to expect 1-2 months for my ATSA results, but ended up getting them within 2-3 weeks. I didn't get an email or anything like that, but noticed that my job application status had shifted from in review to "referred", so I would just check your application on USAjobs pretty frequently to see if you've gotten the green light. From there you can click on your status to see how you did on the ATSA. It's definitely a toughie but I wouldn't sweat it too much. I left the testing center basically accepting that I would work retail for the remainder of my sad life, yet managed to land a pretty solid score overall so I'm not exactly sure what they look at when determining a placement category. I know another tester who received an email informing them that they did not pass.
