How to Earn a PhD Online

When it comes to earning a doctorate, there are two main categories to consider: the PhD and the applied doctorate, also known as a professional doctorate. PhD programs focus on original research that contributes to a field's body of knowledge. Applied doctorate programs, such as the Doctor of Business Administration (DBA) or Doctor of Psychology (PsyD), emphasize the practical application of advanced knowledge in a professional context.

Both types are terminal degrees, meaning neither is more advanced than the other. Either path entitles the graduate to use the title "Doctor." The question is which format and delivery model fits your life. For working professionals, an accredited online doctoral program may offer a meaningful path forward, without requiring you to pause your career.

This article explains how to earn a PhD online, what to look for in a program, and what to expect along the way.

Can You Earn a Real PhD Online?

Yes. Accredited universities offer legitimate online PhD and doctoral programs. The key factor is choosing an institution with recognized institutional accreditation, which supports the credibility and recognition of your degree. Requirements like coursework, exams, and a dissertation or doctoral project still apply in online formats, just as they do in on-campus programs.

When evaluating whether an online doctorate is legitimate, look for institutional accreditation from an agency recognized by the U.S. Department of Education. Programmatic accreditation may also apply in certain fields. The credential itself is not defined by where the coursework is completed; it is defined by the rigor, requirements, and accreditation standing of the awarding institution.

CalSouthern is a member of the American InterContinental University System. The System is accredited by the Higher Learning Commission (hlcommission.org), an institutional accreditor recognized by the U.S. Department of Education.

How to Earn a PhD Online, Step by Step

Earning an online doctorate follows the same core stages as a traditional doctoral program. The online format changes where and when you study, not what is expected of you academically.

Step 1: Meet Admission Requirements (Often a Master's Degree)

Most doctoral programs require applicants to hold a master's degree in a related field. Some programs may consider applicants with a bachelor's degree and significant professional experience, but a master's degree is the standard expectation. You will typically also need to submit a personal statement, professional references, and a resume.

Step 2: Choose a Program from an Accredited University

Before enrolling, verify that the institution holds recognized institutional accreditation. Review program requirements carefully, including credit hours, residency expectations (if any), and whether the program is designed for working professionals. If licensure matters in your field, research state-specific requirements before selecting a program.

Step 3: Complete Doctoral Coursework

For the first two to three years of a doctoral program, students work to develop advanced knowledge and skills in their chosen discipline. Online programs typically deliver this coursework through asynchronous formats, discussion boards, and digital resources, allowing students to study around professional and personal schedules. Courses taken during this stage count toward the program's credit requirements.

Step 4: Pass Comprehensive or Qualifying Examinations

Once coursework is complete, doctoral candidates typically sit for a comprehensive exam, sometimes called a qualifying exam, preliminary exam, or "orals." In PhD programs, this exam tests whether the student is prepared to advance to the dissertation phase. In applied doctorate programs, a similar comprehensive exam assesses readiness to move into the doctoral project phase. Format, timing, and structure vary by institution and discipline.

Step 5: Complete a Dissertation or Doctoral Project

This is the defining stage of any doctoral program. A PhD dissertation addresses a gap in the existing academic literature through original research. An applied doctoral project, by contrast, applies existing knowledge to a real-world problem or professional challenge.

Either way, candidates work closely with a faculty mentor or dissertation committee through proposal development, research, writing, and a formal defense. Online programs support this process remotely through video conferencing, cloud-based research libraries, and digital submission portals.

What to Look for in an Online PhD Program

Not all online doctoral programs are structured the same way. When evaluating options, consider the following:

• Institutional accreditation: Confirm the institution holds accreditation recognized by the U.S. Department of Education.
• Program format: Determine whether the program is fully asynchronous, partially synchronous, or requires any in-person residencies.
• Dissertation or doctoral project support: Look for programs with a structured framework for dissertation or doctoral project development, not just a standalone requirement at the end.
• Transfer credit policies: Some programs allow you to transfer eligible graduate credits, which may reduce overall time and cost.¹
• Faculty access: Doctoral education depends heavily on mentorship. Understand how faculty-student interaction works in the online environment.
• Timeline flexibility: Some programs allow part-time pacing for working professionals, while others expect full-time enrollment.

How Long Does an Online PhD Take?

Timeline varies by program, field, pace of study, and whether you enter with a related master's degree. Many doctoral programs take several years to complete, with the dissertation or doctoral project phase often being the primary variable.

Programs that accept transfer credits, offer year-round enrollment, or allow accelerated pacing may be shorter for some students. However, many factors affect individual time to completion, including course load, extensions, leaves of absence, and how long doctoral project requirements take to fulfill.

CalSouthern's doctoral programs, for example, allow students between three and 10 years to complete their degree. Learners who enroll in one course per term and remain continuously enrolled often complete in approximately four to five years, though individual results vary.²

Earning a PhD Online While Working Full-Time

Online doctoral programs are often designed with working professionals in mind. Asynchronous coursework means you can study during evenings, weekends, or other times that fit around your schedule, without needing to relocate or take time off work.

That said, doctoral education is genuinely demanding. The dissertation or doctoral project phase requires sustained research, writing, and engagement with faculty, which takes real time and effort alongside a full-time career. Online flexibility helps, but time management remains important.

CalSouthern's doctoral programs are specifically structured so that working adults can pursue their degree without leaving their careers. The integrated dissertation development framework builds doctoral project work into credit-bearing courses throughout the program, which can help reduce the uncertainty that often causes candidates to stall at the dissertation stage.

Are Online Doctorates Respected by Employers?

Employers generally evaluate a doctorate based on the accreditation standing of the awarding institution and the relevance of the degree to the role, rather than on whether coursework was completed online or on campus. A doctorate from an accredited institution that aligns with your field and professional goals is the most meaningful factor in how the credential is perceived.

It is worth noting that perceptions can vary by employer and industry. Researching how a specific degree type is regarded in your field, and speaking with professionals who hold similar credentials, can help inform your decision.

Online Doctorate Options: With or Without a Traditional Dissertation

This distinction is more nuanced than it first appears.

Most PhD programs require a traditional dissertation, meaning original research that identifies and addresses a gap in the academic literature. This remains true in online PhD programs.

Some applied or professional doctorates replace the traditional dissertation with a doctoral project or capstone, which applies existing knowledge to a practical professional problem. This is common in programs such as the DBA or the PsyD in Applied Psychology.

The right choice for you depends on your academic goals. If you are drawn to original research and potentially academic work, a PhD may be more aligned. If your interest is in applying advanced knowledge to a professional context, an applied doctorate may be a stronger fit. Read more about the distinction in What Is a DBA Degree.

Cost and Affordability Considerations

Doctoral education is a significant financial investment, and online programs vary widely in cost. When comparing options, look at total program cost rather than per-credit cost alone, since credit requirements differ across programs.

Some considerations that may affect overall cost:

• Transfer credits: Programs that accept transfer credits can reduce the total number of credits required.¹
• Tuition structure: Some institutions, including CalSouthern, lock in tuition rates upon enrollment for continuously enrolled students, which can help with financial planning.
• Payment options: Look for institutions that offer interest-free payment plans or institutional grant opportunities.³
