I know this is probably a random question but it popped into my head and got me thinking, why do nurses ( and other professionals for that matter, ie. Doctors, teachers lawyers) Have to take a test to get licensed to practice AFTER they went all through school. If they went through school and already were able to pass their respective program with good remarks and graduate, wouldn't that already mean they are already qualified to practice?
Kind of like accounting, if an accountant passes an accounting program they don't need a license to do accounting, only if they choose to.
