2027 Best Online PhD Programs With Part-Time Study Options

Business / DBA Programs

A business PhD is generally the better match for someone seeking to produce original research in management, accounting, or another business discipline. A Doctor of Business Administration (DBA) is a separate, typically practice-oriented credential - not an online PhD substitute. Many research-intensive business PhDs expect substantial campus participation and full-time study. If you need part-time online enrollment, confirm that the PhD itself permits it and ask how students conduct research, meet advisers, and satisfy any teaching or residency requirements. A DBA may fit an applied leadership goal better, but compare its actual curriculum and outcomes first.

Education / EdD Programs

A PhD in education usually emphasizes original research into learning, policy, or educational systems. An EdD often emphasizes applying evidence to professional problems; it is not a PhD. For a working educator, the decisive questions are whether the PhD permits part-time enrollment, whether research meetings fit the school calendar, and whether data collection can occur in an approved setting. Check dissertation and campus requirements before assuming that online courses make the whole degree remote. Choose an EdD instead when its applied objectives better match your goals.

Educational Leadership Programs

An educational leadership PhD may suit someone researching school systems, governance, or higher education. An educational leadership EdD may better serve an experienced practitioner addressing a workplace problem. The distinction is the credential and the program's research purpose, not whether courses use video. Prospective part-time PhD students should ask how often required research seminars run, whether their intended adviser supervises remote students, and whether the dissertation topic needs access to schools or institutional records. Neither degree automatically provides a school-administrator credential; check state rules separately.

Psychology Programs

Online, part-time psychology PhDs need especially careful scrutiny if your goal is clinical practice. Research-focused psychology study and a psychologist-licensure pathway are not interchangeable. Check the program's exact specialty, accreditation relevant to your intended license, supervised training, internship arrangements, and your state board's education requirements. Practica and internships may require substantial in-person time even when classes are online. For nonclinical research goals, prioritize faculty fit, methods training, and access to participants or data. Do not assume a PsyD - or any psychology doctorate - automatically leads to licensure.

Nursing / DNP Programs

A nursing PhD prepares students principally to conduct nursing research; a Doctor of Nursing Practice (DNP) is a distinct practice-focused degree. Working nurses considering a part-time PhD should examine research mentorship, statistics preparation, and whether their clinical schedule leaves dependable time for dissertation work. Ask whether campus sessions or research activities are required and whether assistantships are open to part-time students. A DNP may be a closer fit for an advanced-practice or systems-improvement goal, but neither degree alone replaces applicable nursing licenses, certifications, or role-specific requirements.

Public Health Programs

A public health PhD centers on original research, which may involve epidemiology, health policy, or population-level methods. A Doctor of Public Health (DrPH) is a different credential often oriented toward practice and leadership. Online doctoral coursework may still lead to scheduled research seminars, field-based data collection, or an in-person defense. Before choosing a part-time PhD, identify a faculty member whose methods and subject area fit your project and ask whether they supervise remote, part-time researchers. For practice leadership, compare the DrPH's requirements rather than treating it as the same degree.

Computer Science Programs

A computer science PhD can support research in areas such as algorithms, systems, or artificial intelligence, but employer demand for technical skills does not make doctoral research necessary for every computing job. Part-time online applicants should verify that their intended research group accepts remote participation, what computing resources they need, and whether examinations or defenses require travel. Regular adviser collaboration can matter more than asynchronous lectures. If your goal is to apply established tools rather than develop new knowledge, compare a master's degree or focused professional experience first.

Cybersecurity Programs

Cybersecurity PhDs generally investigate new knowledge about secure systems, privacy, or risk; they are not interchangeable with professional certifications. A working applicant should ask whether the intended research requires restricted data, specialized facilities, or scheduled collaboration that cannot be completed remotely. Confirm that part-time enrollment is available throughout the dissertation stage, not merely during coursework. For many security operations or management roles, experience and relevant certifications may be more direct than a PhD. Choose doctoral study when the research question and faculty expertise justify the commitment.

Social Work / Human Services Programs

A social work PhD typically prepares students to investigate policy, services, or interventions. A Doctor of Social Work (DSW) is a separate professional doctorate whose emphasis depends on the program. If you plan to work while studying, ask whether research can use approved community partnerships and how the program supports part-time dissertation students. Field access, ethics approval, and participant recruitment can affect your timeline. A doctorate does not itself grant a social work license; verify state requirements and the qualifications needed for your intended role.

Public Administration / Public Policy Programs

A PhD in public administration or public policy may fit someone investigating how governments design, deliver, or evaluate programs. A Doctor of Public Administration (DPA) is a different credential, often directed toward professional practice. For a part-time online PhD, check access to usable data, faculty expertise in your methods, and whether policy seminars or research workshops require live attendance. Public-sector leadership roles also depend on experience and hiring criteria; a doctorate is not an automatic promotion. If applied management is your priority, compare the DPA and relevant master's-level options.

The best online part-time PhD is the one that both permits your intended schedule and supports your research goal. No school should be treated as a verified recommendation merely because it advertises an online doctorate: the award may be a professional doctorate, and the PhD may require full-time enrollment. Without confirmation of each program's current doctoral-level policies, a ranked list of institutions would be misleading.

The comparison below identifies where to focus your search. It compares research fit and the main scheduling constraint, not unverified promises about particular schools.

Use that shortlist to seek written answers from departments. Availability can differ by specialization and adviser, even within the same university.

Begin with your research question and career goal, then assess programs against evidence you can obtain from their current catalogs, handbooks, admissions offices, and faculty. These checks expose the most consequential mismatches before you commit.

1. Confirm the award is a PhD and obtain the published policy allowing part-time enrollment through dissertation completion.
2. Ask the department to identify every required live session, campus visit, examination, research activity, and defense arrangement.
3. Discuss your topic with a potential adviser and ask how remote, part-time students receive research supervision.
4. Request a personalized tuition and fee estimate, plus written funding eligibility and time-limit policies.
5. Check institutional accreditation and, where relevant, program accreditation and state licensing rules.

Two common mistakes are choosing from a ranking without checking adviser fit and budgeting from advertised tuition alone. If a department cannot explain its part-time dissertation pathway or its required in-person activities, resolve those uncertainties before applying - not after enrolling.
