Skills and Competencies

Throughout your program, you will acquire and hone many skills essential for your professional success. Below, we highlight six skills online Ph.D. in public health programs instill in their students.

Public Health Licensure

Online Ph.D. in public health graduates can work as postsecondary teachers, academic researchers, and policy advisers without holding state-issued licensure or industry certification. However, states regulate many public health professionals through licensure requirements, such as passing examinations, possessing supervised work experience, and passing continuing education courses.

In your career, you can expect to work with or supervise licensed public health professionals. Therefore, you should research your state's public health licensure information: who needs licensure, how to attain one, and licensure renewal requirements. As you learn more about licensure regulations, consider how they might impact your future work environment and the healthcare professionals you supervise. Also, keep in mind that public health Ph.D.s craft their states' licensure requirements.

Although your future career may not require you to earn a license, you should only consider doctoral programs that meet your state board of licensure's academic standards. In other words, make sure that your program holds either regional or national accreditation. If your program does not possess one of these essential accreditations, prospective employers may not regard your degree as valid.

When researching programs, you should pay close attention to those that boast field-specific accreditation. The Council on Education for Public Health (CEPH) accredits only the nation's best bachelor's, master's, and doctoral public health programs. If programs on your shortlist possess field-specific accreditation from other agencies, research those agencies to determine their credibility. You may do so by comparing their accreditation requirements against those mandated by CEPH.
