That's true, but for some jobs here it is required to have proper certification just to access certain data or materials. That requires (a higher level) education. Since most of us (my collegues and me) are almost all university educated (either a bachelor a master or a ph.d) taking the full course is often not necessary because parts of it are already covered by earlier education (e.g. philosophy, economics, statistics). You will obtain the full certification, though. Note these particular qualifications are recognized in the US.
