What is the difference between a PhD and a professional degree in the United States?

A PhD, or Doctor of Philosophy, is a research-focused degree typically awarded in academic fields, such as humanities, social sciences, and natural sciences. A PhD program usually involves extensive coursework, a comprehensive examination, and a dissertation that demonstrates the student's ability to conduct original research in their chosen field.

A professional degree, on the other hand, is designed to prepare graduates for specific careers, such as medicine, law, dentistry, or business. Professional degrees typically require a combination of classroom instruction and practical training, such as internships or residencies. These programs usually have specific licensing or certification requirements that must be met in order to practice in the field.

While both types of degrees require a significant amount of time and dedication, they differ in their focus and objectives. A PhD is intended to prepare students for careers in academia, research, or other specialized fields, while professional degrees prepare students for specific occupations or professions.
