Public Health Degree Guide
The complete resource for students who want to study Public Health — covering entry requirements by region, year-by-year subjects from epidemiology and biostatistics through to global health and health systems, the MPH postgraduate pathway, career specialisations across health agencies, international organisations, and research institutions, and public health professional salary expectations at every career stage.
What is a Public Health Degree?
Public health is the science and art of preventing disease, prolonging life, and promoting health through the organised efforts of society — public health professionals work at the level of communities and populations rather than individual patients, using epidemiology to understand disease patterns, biostatistics to analyse health data, health policy to shape government responses, environmental health to address physical and chemical hazards, and health promotion to change behaviour and social determinants of health.
Students study epidemiology and disease surveillance, biostatistics and quantitative methods, health policy and systems, global health, environmental health, social determinants of health, health promotion and behaviour change, health economics, infectious disease control, maternal and child health, non-communicable disease prevention, research methods, and increasingly data science and digital health — with a blend of scientific rigour and policy relevance distinguishing the best programs.
The degree suits students with a genuine commitment to health equity and social justice, strong analytical and quantitative ability, an interest in both the science of disease and the policy and social structures that determine health outcomes, resilience to work on complex problems with no easy solutions, and the ability to communicate evidence to diverse audiences including politicians, communities, and the media — public health rewards students who want to make a difference at a population level rather than an individual clinical level. You can use the GPA Calculator to check minimum eligibility against your target programs.
Public health is offered as an undergraduate degree — typically three years in the UK as a BSc in Public Health or Health Sciences, or four years in the USA — and as a postgraduate program — the Master of Public Health or MPH is the most widely recognised professional qualification in the field and is typically the preferred entry point for professional public health careers, requiring an undergraduate degree in any health, science, or social science subject as a prerequisite in most countries.

Public Health Degree Entry Requirements
Public health is a multidisciplinary field and entry requirements reflect this — science subjects are valued for analytical rigour but social science backgrounds are equally welcome at many programs, making public health more accessible than single-discipline health sciences.
USA Entry Requirements
For undergraduate public health programs at US universities, most mid-tier programs require a high school GPA of 3.0 to 3.5 on a 4.0 scale. Highly selective programs at Johns Hopkins, Harvard, Columbia Mailman, and UCLA Fielding typically require GPAs of 3.5 or above and are significantly more competitive. Strong performance in Biology, Mathematics, and Social Sciences at high school level is advantageous. It is important to note that in the USA the Master of Public Health (MPH) is the primary professional qualification and most senior public health careers require an MPH rather than just a bachelor's degree in public health — students should plan their career pathway accordingly from the start. International students require IELTS 6.5 or TOEFL iBT 80 or above.
Use the GPA Calculator, SAT Score Calculator, and TOEFL Score Calculator. Browse more tools on the calculators directory.
UK Entry Requirements
In the UK, undergraduate Public Health or Health Sciences degrees typically require A-level grades of BBC to ABB depending on the institution, with Biology or another science subject strongly preferred though not universally required. Many UK public health programs are also available as postgraduate MSc or MPH programs for graduates of any health, science, or social science discipline. The most competitive programs at LSHTM, UCL, and Edinburgh require higher grades and are primarily postgraduate. International students typically require IELTS 6.5 to 7.0 overall.
Use the A-Level to GPA Converter and the IELTS Band Calculator.
International Entry Requirements
International students applying to public health programs abroad will find entry requirements generally more accessible than for medicine or engineering at undergraduate level, though competitive postgraduate MPH programs at leading schools are highly selective. For Indian students, 65 to 75 percent or above in board exams with strong science or social science performance is generally expected for mid-tier programs. IB Diploma scores of 28 to 34 are accepted at most programs. International students with backgrounds in nursing, medicine, dentistry, or allied health professions are particularly sought after by postgraduate public health programs.
Use the CGPA Calculator and SmartCGPA English Test Calculators.
Postgraduate Pathways in Public Health
While undergraduate public health degrees provide an excellent foundation, the Master of Public Health and doctoral programs are the primary qualifications for senior public health careers in most countries — understanding the postgraduate landscape is essential for planning a public health career from the beginning. Global priorities are increasingly shaped through cooperation with agencies such as the World Health Organization.
Master of Public Health — MPH
The MPH is the most widely recognised professional qualification in public health globally and is the standard entry qualification for professional public health roles at health agencies, international organisations, NGOs, and government health departments.
Programs are typically one year full-time in the UK and two years in the USA — covering core public health competencies including epidemiology, biostatistics, health policy, environmental health, and social and behavioural sciences alongside specialist electives and a dissertation or practicum.
Leading MPH programs include those at the London School of Hygiene and Tropical Medicine (LSHTM), Johns Hopkins Bloomberg School of Public Health, Harvard T.H. Chan School of Public Health, Columbia Mailman School of Public Health, and the London School of Economics. Admission to top MPH programs is competitive and typically requires a strong undergraduate degree, relevant work or volunteer experience in a health setting, and increasingly GRE scores at US institutions.
Doctor of Public Health — DrPH
The Doctor of Public Health is a professional doctoral degree designed for senior public health practitioners who want to develop advanced leadership and research skills — distinct from the PhD which is a research doctorate for those pursuing academic careers.
The DrPH typically requires three to four years of part-time or full-time study following the MPH and is offered at a small number of leading public health schools including Harvard, Johns Hopkins, and LSHTM.
The DrPH curriculum covers advanced public health leadership, complex problem-solving, advocacy, and applied research — producing graduates who move into senior director and leadership roles at public health agencies, international organisations, and major NGOs. It is the highest professional qualification in public health practice.
PhD in Epidemiology or Public Health
A PhD in Epidemiology, Biostatistics, or Public Health Sciences is the terminal research degree for those pursuing academic careers in public health research or senior research positions at institutions such as the CDC, NIH, MRC, and NIHR.
Programs typically require four to five years of doctoral research following an MPH or equivalent master's degree and culminate in an original research thesis contributing new knowledge to the field.
Public health PhD programs at top universities are typically fully funded with a stipend and provide exceptional training in research methods, scientific writing, and grant acquisition. Graduates of public health PhD programs work as professors, senior research fellows, principal investigators, and chief scientific advisors at major health research institutions globally.
Fellowship Programs and Specialist Training — UK
In the UK, public health practice is a medical or dental specialty for doctors and dentists who complete the Specialty Training in Public Health program — a five-year training program leading to Fellowship of the Faculty of Public Health (FFPH) and registration on the GMC specialist register.
Non-medical professionals can also become consultants in public health through the non-medical public health specialty training route — a similarly rigorous five-year program open to graduates with an MPH or equivalent qualification and relevant public health experience.
Consultants in public health work at local authority, NHS, and national agency level leading health protection and health improvement functions. The UK public health workforce also includes a large number of specialists and practitioners in roles such as health protection nurse, public health analyst, and health intelligence specialist who do not complete the full specialty training but hold relevant postgraduate qualifications.
How to Get Into a Public Health Degree
- 1
Build a Strong Science and Social Science Foundation
Public health draws on both natural science — particularly Biology, Chemistry, and Mathematics — and social science including Sociology, Psychology, and Economics — so students who combine strong performance across both disciplines are well-prepared for the multidisciplinary demands of public health study. Biology is the most directly relevant science subject given the centrality of health and disease to the curriculum.
- 2
Develop Awareness of Current Public Health Issues
Public health is an inherently topical discipline — following developments in infectious disease surveillance, health inequalities, environmental health policy, and global health through reliable sources such as The Lancet, British Medical Journal, and WHO publications demonstrates the kind of intellectual engagement that public health admissions tutors look for in personal statements.
- 3
Meet the GPA or Grade Requirements
Check the specific requirements of your target programs and use SmartCGPA's GPA Calculator to track your standing. For most undergraduate public health programs BBB or above at A-level is sufficient; for competitive postgraduate MPH programs work towards a strong upper-second or first-class undergraduate degree and relevant experience.
- 4
Gain Relevant Health or Community Experience
Public health programs and postgraduate admissions committees value applicants who have engaged with health systems or community health through volunteering, work experience, or research — this can include volunteering with health charities, working in healthcare administration, assisting in epidemiological research, or community development work in health-related areas.
- 5
Demonstrate English Proficiency
International applicants must submit IELTS or TOEFL scores — most public health programs require IELTS 6.5 to 7.0 or TOEFL 80 to 100. Use the IELTS Band Calculator to check your band score.
- 6
Prepare for Standardised Tests if Required
US applicants should prepare for the SAT — use the SAT Score Calculator to interpret practice results. For postgraduate MPH programs at US institutions, the GRE is widely required and should be prepared for with particular attention to the Quantitative and Verbal sections.
- 7
Apply via UCAS or Common App Articulating Your Public Health Motivation
UK students apply through UCAS with a personal statement that demonstrates genuine engagement with public health issues, awareness of the difference between public health and clinical medicine, and any relevant experience — admissions tutors are looking for students who understand that public health operates at a population level and who can articulate why this approach to health matters. US students should highlight relevant research, volunteer, or policy experience in their application essays.
