As people live longer and in increasingly close contact, questions of public sanitation and disease control become greater issues to local governments and educational institutions. According to the U.S. Bureau of Labor Statistics (BLS), medical and health services managers earn an average annual salary of more than $98,000, and positions are projected to grow by 20% by 2026.

Healthcare professionals work one on one with local community members to identify public health issues and gather analytical data. They then translate that information for companies, institutions, nonprofit organizations, and government bodies to help them implement change and improve healthcare. Professionals in this field use interpersonal communication skills and scientific and statistical analysis. They infuse human backstories into scientific reporting to positively influence public and institutional healthcare organizations.

Should I Get a Doctorate in Public Health?

Pursuing a Ph.D. in public health is no simple task. Multiple factors determine your preparedness to enter a doctorate in public health program, your ability to stay on track, and the value of your degree after graduation. Many programs require students to first obtain a bachelor's or master's degree in public health or a related field. Similarly, some programs encourage one to two years of previous professional experience in the field to ensure incoming students are informed on and dedicated to public health issues.

For students starting their Ph.D. program immediately after completing a master's, on-campus programs are the most logical choice, because they follow similar standards in class participation and assignment submissions.

How to Choose a Doctoral Program in Public Health

Prospective students should consider program length, curriculum requirements, and degree costs of each institution when choosing a doctorate in public health program. As you search for the right institution, account for your personal needs, along with the requirements of each of potential program.

A Ph.D. in public health typically takes between three and four years to complete. All students must cover a core curriculum of advanced public health studies, usually 40 to 60 credits total, before moving on to dissertation research and writing. Coursework often includes classes in epidemiology, biostatistics, health policy regulations, and preventative medicine. The dissertation then builds from students' previous coursework, offering a space for them to execute research interests and demonstrate their analytical and communication skills to future employers. Dissertation research takes as much time as students are willing to give, so they should plan a dissertation timeline to help them stay on track.

Degree cost also factors into the program selection process, as tuition is the top financial burden of Ph.D. program participants. The longer you take to complete a program, the more tuition expenses you incur. In this regard, on-campus or hybrid programs may help you stick to a graduation timeline, while online program can stretch the degree process to five to six years, depending on your course pace. For students juggling busy personal and professional lives, an online program may be worth the length, since it offers so much flexibility.

Programmatic Accreditation for Doctoral Programs in Public Health

Accreditation is a valuable component to any Ph.D. in public health, as it guarantees the value of your education and the quality of your program. Accreditation assures future colleagues and employers that your skillset meets the needs of the community or institution. All public schools are required to meet national accreditation standards set by the U.S. Department of Education (ED). Colleges and universities are monitored and accredited by regional governing bodies. Furthermore, the Council on Education for Public Health (CEPH) is an independent organization that certifies all levels of public health education, and is also recognized by the ED. Check for program accreditation on the institution's website, the ED's accreditation search engine, or the CEPH's current accredited schools list.

Doctorate in Public Health Program Admissions

Given the accreditation standards that each public health program must meet, most doctorate programs for public health require similar application materials and educational benchmarks. On-campus programs request traditional information regarding students' educational backgrounds, professional experience, and relevant test scores. Online programs, by contrast, often request more detailed application materials, because the online student body works remotely.

When applying for public health programs, you should identify about four prospective institutions to apply to. Make sure each program you select offers coursework in your intended specialization area and a projected degree timeline that fits your desired schedule. Also, check the credentials of each institution to make sure the program is validated by nationally recognized accreditation bodies, such as CEPH.


  • Degree: Proof of previous degrees is vital to acceptance to a Ph.D. program. Check each individual program to see if a bachelor's or master's in public health is required prior to enrollment.
  • Professional Experience: Given the strong communication skills required in the professional sphere of public health, previous field experience is often encouraged or required by doctorate programs. Work with local government or health institutions for one to two years before applying for a Ph.D. program, or volunteer with a local nonprofit to prepare yourself for a doctorate in public health.

How Long Does It Take to Get a Doctorate in Public Health?

The length of a public health doctorate depends on multiple factors, including degree requirements, dissertation research, and personal commitments. A typical Ph.D. in public health can takes three to four years to complete, with two years of coursework and one to two years of dissertation research and composition.

Depending on a school's requirements, more classes or specific dissertation benchmarks may extend the degree to five years. Students who want to expedite their programs can do so by taking more classes in a given term (for example, three to four courses instead of the normal two), and by sticking to a strict dissertation completion schedule. Most students execute their dissertation research and composition independently, so they must give themselves deadlines to move through the final hurdles quickly. Your personal and professional lives and quality of life are the final determining factors in degree length. Be pragmatic: Consider how much time you can devote per week toward coursework, research, and composition. Realistic expectations are the secret to success in graduate school.

How Much Is a Doctorate in Public Health?

The financial aspect of a Ph.D. in public health should be of serious concern for all potential applicants. In-state tuition for Ph.D. programs run between $6,000 and $9,000. Out-of-state programs are typically double that cost -- between $12,000 and $20,000 -- and sometimes go even higher. Due to this huge discrepancy, consider degree opportunities near you. Because accreditation mandates such stringent standards, universities across the U.S. provide roughly similar degree specializations. Online programs often cost the same per term as on-campus options at the same institution, but some programs waive the increased out-of-state tuition to encourage nationwide enrollment.

Beyond tuition, housing fees also affect overall degree costs. Living on-campus provides the benefit of room and board, but also accrues the most financial burden (an additional $6,000 to 8,000 per term). Living off-campus in an apartment or shared living space may mitigate these expenses. Completing coursework remotely by living in less-populated areas or with family offers the most financial gain. Even so, hidden costs to a Ph.D. in public health can catch students off-guard, particularly regarding software and other technological costs, which are unavoidable in a modern classroom situation.
