Online doctoral degree programs are growing in availability and credibility. However, only a select number of universities offer a full selection of accredited PhD programs online.

In most fields, an online PhD is considered a terminal degree, which means it is the highest degree that you can earn in your field. This means that online doctoral programs for PhD students can lead to opportunities for leadership, public consultation, research, and post-secondary education in your field. An online PhD can also lead to a career with a much higher than average salary.

Online PhD candidates are typically already working at a high level in their field. This means that students seeking their doctorate must balance existing work and personal responsibilities with a challenging course of education. For many graduate students, online courses and fully online programs provide a way to achieve this balance.

For a look at how these online doctoral programs stack up against traditional on campus programs, check out our look at the 50 Best Graduate Schools in the U.S.

About Accredited Online PhD Degree Programs

Online doctoral students have plenty of options, but quality and credibility are important when it comes to finding an online PhD. The best online doctorate programs will have proper accreditation:

  • Institutional Accreditation: Accreditation is vital for online doctoral programs. It signifies that the online Ph.D programs offered by the graduate school are in compliance with the standards of a Department of Education-approved accrediting body.

    • A school must also be accredited in order to offer federal financial aid to its online doctorate candidates. When looking for an online doctoral program, seek out options with accreditation from a colleges and schools commission in your region. This stamp of approval is critical for ensuring the quality and credibility of your online program.

  • Programmatic Accreditation: In addition to institutional accreditation, be sure that you are only considering online doctorate degree programs with programmatic accreditation.

    • For instance, if you seek a doctor of nursing practice, be sure that your online doctoral degree program has accreditation from the Commission on Collegiate Nursing Education (CCNE). If you seek a PhD in business administration, be sure you only consider online degrees with programmatic accreditation from the Accreditation Council for Business Schools and Programs (ACBSP).

    Programmatic accreditation ensures you only select from online PhD programs respected in your field.

  • Carnegie Classification: The Carnegie Classification of Institutions of Higher Education, or as it is more commonly known, the Carnegie Classification, is a framework for categorizing all accredited, degree-granting institutions in the United States.

    • Originally formulated in 1970 by The Carnegie Foundation for the Advancement of Teaching, and administered through the University of Indiana’s Center for Postsecondary Research since 2014, the Carnegie Classification is “the leading framework for recognizing and describing institutional diversity in U.S. higher education.”

    Under this classification, top research universities for doctoral degrees and PhD candidates are identified as either R2: Doctoral Universities for “high research activity” or R1: Doctoral Universities for “very high research activity.” Look for these classifications when considering options for your online Phd programs.

Key Point: The best online doctoral programs will have both institutional and programmatic accreditation.

Admission Requirements

Schools that offer online doctorate programs have different admission requirements. However, in most online doctoral programs will carry the same basic threshold for admission:

  • A completed online application
  • Official undergraduate college transcripts
  • A cumulative GPA of at least 3.0
  • GRE scores, MAT scores, or GMAT scores
  • Letters of recommendation
  • Personal interviews
  • Personal statement or essay
  • Plan of study

Key Point: In most cases, you’ll be eligible to enter a doctoral degree online after earning a bachelor’s degree. However, some specialized online PhD programs may require you to have earned a master’s degree as well.

Curriculum and Courses

As with other advanced degree and graduate programs, research is the central component of your online PhD program. This is true for fully online doctorate degrees as well as hybrid degrees combining online education with traditional on-campus courses.

Regardless of whether you complete a traditional, hybrid or online doctoral program, the typical time to completion is five to seven years.

The typical components of your online PhD program may include:

Foundational Courses

While some foundational online doctorate courses may be focused on your specific discipline or area of study, most courses will focus on research methods and experimental design. You may be able to complete many of these requirements through online classes.

Examinations for PhD Candidacy

Many online doctoral students are required to complete certain examinations to enter into online PhD candidacy. This will typically occur after you’ve completed one to two years of foundational courses.

Dissertation

In most cases, the central component of your online PhD program will be the completion of your dissertation. After gaining status as an online PhD candidate, you will typically work closely with a professorial advisor or mentor to develop an original research question.

This research question will form the basis of your dissertation—an ongoing project designed to address this research question through applied research. While you will work closely with your advisor or mentor, much of your dissertation will be rooted in independent research. This is especially true for students pursuing an online PhD.

Oral Defense

Upon completion of the written portion of your dissertation—which will typically present the findings from your original research project—you will be expected to defend your findings. This “oral defense” will typically be conducted by a commission of professors and experts in your field. PhD candidates in some online degree programs may be able to conduct this defense via teleconferencing.

Teaching Requirements

Some online Ph.D programs will also include a teaching component, which will require you to work as an adjunct professor or teacher’s assistant in an undergraduate or graduate school. It may be possible for students in the online doctoral degree program to also serve teaching requirements by instructing online students.

Key Point: The online PhD is a research-focused degree. Your dissertation will be a central part of your online doctoral degree program.

Careers for Students Who Complete Online Doctoral Degree Programs

Accredited online doctoral programs are generally terminal degree programs. This means that students who complete credible online doctoral programs in their field are generally eligible for top positions and opportunities in their field. These opportunities, and the pay scale, may differ from one field to the next.

That said, the Bureau of Labor Statistics notes that, in 2023, working professionals with a PhD earned more per week than other Americans in every educational demographic. According to the BLS, the median weekly earning for graduate students with a doctoral degree was $1909. By contrast, those with a master’s degree earned a weekly median of $1574, while bachelor’s degree holders earned a median of $1334.

These higher earnings are reflective of the rarified professional opportunities that await those with a PhD in their field. Working professionals who earn an accredited online doctorate may be eligible to work in the following areas.

  • Theoretical Research
  • Scientific Research
  • Publishing
  • Sociology
  • Post-Secondary Education
  • Public Policy Consultation
  • Clinical Practice
  • Organizational Leadership

Key Point: According to the Bureau of Labor Statistics, students with a doctorate will earn more than graduates with a bachelor’s or master’s degree.

What’s the difference between online doctoral programs and online Ph.D programs?

Technically, a PhD is a type of doctorate degree. This means that all online PhD candidates are doctoral students. By contrast, not all doctoral students are PhD candidates.

The primary distinction is that doctoral students are primarily focused on putting existing theories into practice. Depending on your chosen field, your online doctoral degree may require participation in an educational leadership program, engagement in clinical practice, work as a resident in a nursing program, and much more.

By contrast, online PhD students are focused on creating new knowledge in their area of study. This usually means that online PhD candidates are focused on introducing new theories, creating research projects around these theories, and presenting new findings that demonstrate a mastery of existing knowledge and the insight to introduce new ideas into the field.

Today, more working professionals than ever before are pursuing both online doctoral degrees and online Phd programs.
