A doctorate is a broader category that includes research degrees like the PhD and professional degrees like the JD, DBA and MD. Professional doctorates apply existing knowledge to real-world problems and typically require a capstone or applied project instead of a dissertation.

A PhD is a specific type of doctorate focused on producing original theoretical knowledge. A PhD prepares scholars and researchers for academic and research careers, and requires candidates to complete extensive research and a dissertation that contributes new knowledge to the field.

Professional doctorates and PhD degrees both confer the title of “Doctor” and represent the highest academic level, but the PhD is theory- and research-focused, while professional doctorates are practice- and application-focused.

What Are the Types of Doctorate Degrees?

The main types of doctorate degrees fall into three main categories: research doctorates, professional doctorates and honorary doctorates.
