What is the higher degree of doctor?

Answer 1

A research doctorate is usually considered the highest level of doctorate one can achieve, and in the United States that usually means a PhD, though there are other forms within the US and on a country by country basis (or even institution by institution). Then there are professional doctorates that denote a certain level of skill or knowledge in a field, such a medicine (Medical Doctor) or law (Juris Doctor). Typically, these are listed as "lower" in rank due to the requirements to achieve them (not to belittle a holder nor their field, of course) and tradition. For example, a person with a PhD and JD would formally write their name as "First Last Name, PhD, JD".
