Is English not your first language?

The JD is a doctorate level degree granted by law schools, and American law schools only accept people who already have a bachelor’s level education at a minimum. Like I said in my other comment, the bar exam is the exam people with JD degrees can take to become licensed attorneys. their membership in the Bar Association is their professional qualification.

That is absolutely incorrect. A JD is a juris doctorate and is considered a postgraduate degree in the United States. There are some places where law degrees are granted at the bachelor’s level, but not the US. You’re making the same mistake as the Rogan crowd here by looking at a surface level, single sentence from Wikipedia (which is referring to the Canadian system btw). The law degree itself is only “entry level” because JD holders have to pass a licensure exam (the "professional qualification) before they are allowed to be practicing attorneys. There are quite a few people who have law degrees, but don’t take the exam because they intend to use their law degrees in other ways.
