How Many Years Is a PhD in Public Health Online?

To complete an online PhD in Public Health degree program, students should be prepared to invest at least four years beyond their bachelor’s degree or two to three years beyond their master’s degree. However, some programs allow significantly more time for completion, with a maximum of up to eight years in some cases. Most online programs consist of two years of coursework followed by a dissertation process that can last between two and six years. The total degree completion time can be affected by several factors, including the specific school, area of specialization, choice of full-time or part-time study, and the student’s starting point (either with a previously-earned bachelor’s or master’s degree). Those attending part-time should plan on a total of five to six years to complete their degrees realistically.

Should I Get a PhD in Public Health? Should I Earn It Online?

A PhD in public health can be a great choice for just about any research-minded public health student or professional. And programs that include online coursework may be the best way to earn it. But online learning may not be for everyone. Here are 6 important questions that every potential student should answer before pursuing an online PhD in public health.

  1. Are my professional interests definitely centered in the field of public health?
  2. Am I interested in a career in either advanced scientific research or post-secondary academics? If not, a public health bachelor’s or master’s degree may be sufficient to reach your professional goals.
  3. Am I a self-starter and self-disciplined? Both are required for success as an online student.
  4. Am I good at time management? Excellent time management is another crucial skill for any successful online learner.
  5. Am I computer/internet proficient? You don’t need to be a computer scientist to be a good online learner, but a solid proficiency and comfort level with word-processing software, web browsers, and online media platforms is necessary.
  6. Am I comfortable interacting with professors and peers almost entirely online (including submitting papers, chatting, and receiving feedback)? If you’re someone who needs face-to-face interaction to learn, then an online degree program is probably not for you.
