Is the ATC test hard?
Yes, for most people who apply. The FAA says fewer than 10% of applicants are accepted into training. That number is the whole pipeline, not an ATSA pass rate. The test is hard because simple tasks get fast and stacked, and because a medical, a background check, and academy training sit behind it. Nobody honest can quote one pass rate for every country.
Separate the gates
People mix four different filters into one "pass rate". First, are you eligible to apply? For the FAA's standard trainee path that means US citizenship, under 31 at application, English, and a year of work or a degree, or a mix. Second, did the FAA invite you to the ATSA, and did you reach the band that window requires? Third, did you clear the medical and the security check? Fourth, did you finish the academy and then certify in a facility? Failing any one of those ends that attempt. A practice score touches only the second gate, and only as preparation, not as the gate itself.
What "hard" feels like on the day
Candidates describe a long sitting, about 3.5 hours in the FAA's own wording, in a test centre. The items are not obscure facts about air law. The strain is attention: a rule changes, a second task arrives, a number in a headset is close to the number you just typed. People who do well at puzzles on paper still drop items when the pace rises. That is why the drills here are timed.
Academy and the years after
Passing selection is the start of training, not the end of difficulty. Initial FAA training is several months at the Academy in Oklahoma City, paid, and then about one to three years on the job before you are certified at a facility. The FAA's workforce plan is where training losses are reported, and the figure changes. This page will not freeze a washout percentage from a blog.
Europe is a different hard
FEAST has its own stages, and each provider sets the cut. A German Fluglotse process adds language and a medical on top of the aptitude day. Do not import an American percentage into that process. If you want the skill work anyway, the same four drills apply. The FEAST page says what each stage is.
