A doctorate degree is the most advanced degree you can obtain. Doctorate degrees usually require at least 4 years for completion, sometimes even up to 8 years. Imagine the specialized nature of a master’s degree — now, multiply that by 10. People that hold doctorate degrees are usually experts in their fields. Doctorate degrees also provide specific training for certain professional practices.
Doctorate studies are largely independent. Students spend a lot of their time researching a topic that’s approved by a professor and form an original thesis for their dissertation. Universities and colleges often require Ph.Ds from candidates interested in job postings as a professor.
You can pursue a Doctorate Degree after completing a Master’s Degree program. However, some universities allow students to pursue their Ph.D. directly after the completion of a Bachelor's Degree.
