A master of public health (MPH) qualifies you for specialized and supervisory roles in the field. For example, you may run a tobacco-cessation program as a lead health educator or investigate the causes of disease as an epidemiologist.

Most public health master's programs require about two years of full-time study. They provide advanced instruction in subjects like biostatistics, international health systems, and communication strategies for public health. Students may also need to complete an internship or field-based practicum to develop real-world experience.

This guide provides an overview of earning an online MPH, including information on admission requirements, important considerations when selecting a program, and possible career paths after graduation.

What Is Public Health?

Public health is the science of preventing disease and promoting human health, encompassing an individual's physical, psychological, and social well-being. Because of the broad and interdisciplinary nature of the field, public health professionals may specialize in areas like data analysis, public policy, health economics, behavioral and mental health, or occupational safety. They may also serve in a wide variety of roles, including nurse, sociologist, public health inspector, medical microbiologist, or sexual health educator.

As healthcare costs continue to rise, more communities and organizations are making an effort to teach people about healthy behaviors, improve access to preventive services, and develop cures and treatments for chronic health issues. This should lead to an increased demand for the services of public health workers, especially those with advanced training in areas like epidemiology, gerontology, and culturally sensitive care. Many public health professionals also choose to work in developing countries, providing much-needed health and educational infrastructure.

Interview With Annie Evans

Adrianna “Annie” Evans

Adrianna “Annie” Evans

Program Coordinator for Expecting Health

Annie Evans serves as program coordinator for Expecting Health, a maternal and child initiative at Genetic Alliance. She works to engage different stakeholders in Genetic Alliance programs through outreach efforts and the development of usable tools. Annie initially joined the Genetic Alliance team as an intern and was hired full time after graduate school.

Annie earned her bachelor’s degree in biology from Penn State, with minors in international studies and global health. She received her MPH from George Washington University. Her focus was on global health program design, monitoring, and evaluation.

Tell us a little about your day-to-day responsibilities as program coordinator for a healthcare nonprofit. How do the skills you gained in your MPH program apply to the work you do?

Much of my day is spent in the throes of managing projects and communicating about a number of different projects and programs surrounding maternal and child health. I apply the skills I learned in my MPH every day at my job. During my graduate program, I learned skills in program management, program implementation, health communication, and evaluation. These skills help me guide and track the progress of the projects I work on and make sure they are evidence-based and evidence-driven. Additionally, I feel that the global perspective of my program helps me to continually view things from a multicultural and health equity focused lens.

Why did you choose to pursue a master's in public health specifically?

I chose to pursue a master’s in public health because I like the interdisciplinary approach to health. When I first entered college, I thought my interest in biology and health would lead me to a career in medicine. But, gradually, as I gained experience and learned about social determinants of health, I began to appreciate the multitude of factors that influence the health of individuals and communities. Traveling, volunteering in communities, and taking classes outside my major opened my eyes to how education, socioeconomic status, and other factors can influence health. I developed a passion for health equity and social justice and wanted to work in a field that accounted for those factors.

What was the job search like after graduating from your MPH program? Did you feel adequately prepared to enter the workforce upon graduating?

Overall the job search was stressful but ultimately led me to a position that fits my interests and skills. When I began applying, I knew I had a number of hard skills from my MPH that would be useful, but I had to learn how to market myself. I wrote and rewrote many different cover letters and resumes that helped me learn how to highlight relevant skills for different jobs, but I also had to learn how to network. I emailed people for informational interviews and built a network of connections who would send me opportunities they thought I might be interested in. I also relied on connections I made during my MPH program, which were the most fruitful.

Once at my job there was a learning curve, as there will be with any position, but the skills I learned in my MPH program helped me analyze and think strategically. These skills have proven essential to my current position.

What were some of the greatest challenges you faced when completing your MPH program?

One of the greatest challenges in completing my MPH was tackling my culminating experience or "CE." This piece of writing is similar to a thesis but stems from a practical experience in public health. For my CE, I had to design my own research, collect data, and write/present a robust analysis. It was a long, self-directed project that took a lot of work and guidance to complete. I had to be very regimented to continually make progress.

What advice would you give to undergraduate students considering earning an MPH? Is a master's degree worth it?

Undergraduate students considering an MPH should not feel pressured to go into a graduate program immediately after their undergraduate degrees. Work experience in public health is highly valued alongside graduate education, so whether students go into the workforce or straight into a graduate program they will need to learn about what their true career goals are. An MPH is a versatile degree that is usable in many different positions, but graduate school is typically very expensive and individuals considering it should be sure it’s really what they want and not just something they think they have to do.

Do you think it's necessary or important for students to have this kind of biology- or healthcare-focused background when entering an MPH program?

Students interested in MPH programs do not need to have a background in biology or another science. Public health is a multidisciplinary field, so experience in a number of different fields may be useful. It mainly depends on interest.

Personally, my background in biology has been advantageous because several of the projects I work on center around genetic conditions, so having a good understanding of the science helps me communicate with communities.

What additional advice would you give to prospective MPH students?

I would recommend that prospective MPH students talk a lot with MPH graduates out in the field. Since MPH graduates work in a multitude of fields and positions, talking to as many as possible can help prospective students get an idea of all of the possibilities available to them.

I would also recommend that prospective students weigh location when making a decision on where to go to graduate school. Location of a school has a lot of potential impact on prospects for work experience and networking, which can really help supplement the graduate program.

How to Choose a Master of Public Health Program

Where you earn your master's degree in public health will play a role in shaping your professional opportunities throughout your career. Before you select a program, make sure to carefully consider the five factors detailed below.

Accreditation
It is critically important that you choose an accredited program. The accreditation process helps to ensure that schools meet certain academic standards and adequately prepare their students. If you attend an unaccredited program, future employers may not recognize your degree. You also risk missing out on state and federal financial aid.
Cost
Finding an affordable master's program will make earning your degree an even better investment. Generally, public colleges and universities offer lower tuition than private institutions, especially for in-state students. At some schools, you may also qualify for tuition discounts if you or a member of your family has served in the military.
Financial Aid
Scholarships, grants, and other financial aid opportunities can further reduce the overall cost of your education. Start by completing the Free Application for Federal Student Aid (FAFSA), which determines your eligibility for federal grants, work-study positions, and low-interest student loans. You can also research private scholarships offered specifically to students pursuing a master's in public health.
