That's incorrect. In the US, you take the Engineer In Training (EIT) exam when you graduate university, then require 4 years of industry experience before you can sit the PE (Professional Engineer) exam. If you pass that, you can call yourself an Engineer.
But that's only for actual Engineering disciplines. We in software don't need to take an "Engineer" test for the same reason we don't need to take a "Rock Star" test or "Ninja" test. We use the title as a courtesy, not an indication of qualification.
