Certificate Programs in Health Science
A health science certificate is designed for people entering the field without a degree background, those returning to healthcare work after a gap, or professionals who need to add a specific credential to their current role. Post-secondary certificates cover practical specialties like practical nursing, medical assisting, and medical coding and billing, and typically take six months to a year to complete.
At the graduate level, certificates in health science management or health informatics give working healthcare administrators targeted knowledge in areas like insurance regulation, operational management, and organizational behavior, without the time commitment of a full master’s program.
Medical Records and Health Information Technicians
Review and manage patient health records for completeness and accuracy, assign diagnostic and procedural codes for billing purposes, and maintain secure digital records systems. Most positions require an associate degree, but some entry-level roles accept candidates with a certificate and relevant certification.

Bachelor’s Degree in Health Science
A four-year bachelor’s degree in health science typically covers foundational sciences for the first two years, then moves into a chosen specialization. Common tracks include public health, physical therapy, occupational therapy, health information technology, nutrition, and psychology. The specific coursework depends heavily on the concentration and the program.
For some careers, a bachelor’s degree is the minimum required credential. For others, it’s a prerequisite for professional licensing programs like registered nursing or a launching point toward graduate school. Medical and health services managers, who coordinate operations for departments or entire facilities, typically need at least a bachelor’s degree, and the BLS projects that field to grow 23 percent from 2023 to 2033, faster than nearly every other management occupation.
Nutritionists and Dietitians
Work with patients and clients to assess nutritional needs, develop meal plans, and monitor outcomes. Most states require licensure for dietitians, which typically involves completing an accredited program, a supervised internship, and a national exam administered by the Commission on Dietetic Registration (CDR).

Health Educators and Community Health Workers
Design and deliver programs that help individuals and communities understand health risks, manage conditions, and access care. Health educators typically need a bachelor’s degree. Certified Health Education Specialist (CHES) certification is a common professional credential.
Master’s Degree in Health Science
Graduate-level health science programs build on bachelor’s-level knowledge with intensive work in research methods, data analysis, and leadership. Specializations at this level include public health, infectious disease, kinesiology, health informatics, and health administration. Most programs take two years for full-time students.
A master’s degree is typically required for independent research roles, senior management positions in large healthcare organizations, and careers that involve health policy development. Many employers in health administration explicitly prefer candidates with graduate credentials, even for positions where a bachelor’s degree meets the minimum requirement. Our healthcare manager career guide covers those paths in more detail.
Medical and Health Services Managers
Coordinate and oversee operations for healthcare facilities, departments, or physician groups, including staffing, budgeting, billing, and regulatory compliance. The BLS reports a median annual wage of $117,960 for this occupation and projects 23 percent employment growth from 2023 to 2033.

Doctoral Health Science Degree
A doctoral degree in health science is the highest credential in the field, and it’s most relevant for people heading into senior leadership, academic research, or health policy work. Programs typically cover healthcare law and policy, health informatics, research design, and advanced leadership. Applicants usually need a master’s degree in health science or a closely related discipline, and most programs take four years to complete, though timelines vary by school and dissertation requirements.
Post-secondary health science educators, a field where a doctoral degree is often required, are projected to see continued demand driven by enrollment growth in health programs. The range of roles that draw on doctoral-level credentials includes nursing administration, policy analysis, academic faculty positions, and senior roles in public health agencies and nonprofit organizations.
Nursing Administrators
Oversee nursing services across large healthcare facilities, including hiring and supervising nursing staff, establishing care delivery policies, and managing the nursing budget. A doctoral degree (DNP or PhD in nursing) is increasingly expected for top administrative positions in large systems.
Health Policy Analysts
Evaluate healthcare delivery systems, perform cost analyses, assess existing programs, and contribute to the design and implementation of future policies. These roles exist across federal and state agencies, think tanks, and academic research centers.
Post-Secondary Health Educators
Teach health-related courses at the university or college level, develop curriculum, advise students, and conduct research. Most faculty positions at four-year institutions require a PhD or equivalent doctoral credential.
How to Choose a Health Science Degree Program
Program quality varies significantly across institutions, and the credential you earn is only as useful as the program that granted it. These four questions help you evaluate programs objectively before committing.
Is the school and program accredited?
Accreditation is the most important factor. Schools must meet established standards to receive regional or national accreditation from agencies approved by the U.S. Department of Education. Without it, employers may not recognize your degree, and you may be ineligible for federal financial aid. Program-level accreditation matters too. Health science programs are frequently accredited through bodies like the Commission on Accreditation of Allied Health Education Programs (CAAHEP) or the Higher Learning Commission.
Will your credits transfer?
Even accredited credits don’t automatically transfer. Acceptance policies vary by institution. If you’re completing an associate degree with the goal of finishing a bachelor’s at a different school, confirm transfer credit policies with the four-year institution before you enroll in the two-year program. Don’t assume transfer compatibility. Get it confirmed in writing.
What specializations and courses are offered?
Not all programs offer the same tracks. An associate program at one school might specialize in diagnostic sonography, while another focuses on nursing and medical office administration. Check whether elective courses align with your longer-term goals. A student interested in healthcare leadership may need management coursework that isn’t offered in every health science program.
What are the graduation and job placement rates?
A high enrollment rate doesn’t mean much if students aren’t finishing. Ask programs specifically about graduation timelines. Delayed clinicals, for example, can push completion dates back for nursing specializations. Also ask about employer partnerships, career placement offices, and whether the program provides resume and interview support. These services signal that the school is invested in outcomes, not just enrollment.

Frequently Asked Questions
What can you do with a health science degree?
A health science degree prepares graduates for a wide range of clinical and non-clinical roles. At the certificate and associate level, common careers include medical assistant, phlebotomist, dental hygienist, and EMT. Bachelor’s programs open paths to registered nursing, health education, and health administration. Graduate degrees support roles in research, hospital management, policy work, and academic instruction. The specific careers available depend heavily on which credential level you earn and which specialization you choose.
Is a health science degree the same as a public health degree?
Not exactly, though there’s overlap. Health science is a broad umbrella covering clinical, administrative, and research disciplines. Public health is a specific field focused on population-level health outcomes, disease prevention, and policy. A Master of Public Health (MPH) is one of the most common graduate credentials in the public health space and is distinct from a general Master of Health Science (MHS or MHSc). Some health science programs have a public health concentration, but the two aren’t interchangeable.
How long does it take to earn a health science degree?
It depends on the credential level. Certificates typically take six months to one year. An associate degree takes about two years. A bachelor’s degree takes four years, though students with an associate degree may complete one in less time, depending on transfer credits. Master’s programs run about two years for full-time students, and doctoral programs average four years beyond the master’s level.
What accreditation should I look for in a health science program?
Look for institutional accreditation from a U.S. Department of Education-recognized agency, such as a regional accreditor. For program-level accreditation, CAAHEP is the primary accreditor for many allied health programs. Specific disciplines have their own accreditors: the Commission on Dental Accreditation (CODA) for dental hygiene programs, the Accreditation Council for Education in Nutrition and Dietetics (ACEND) for dietetics programs, and the Commission on Collegiate Nursing Education (CCNE) for nursing programs, among others.
Is an online health science degree worth it?
For many concentration areas, yes. Administrative and research-focused health science tracks translate well to online formats. Clinical programs require hands-on practicum components that can’t be completed fully online, but hybrid structures that combine online coursework with local clinical placements are common. The key factor isn’t the format. What matters is whether the program holds proper accreditation and prepares graduates for licensure or certification exams in their target specialty.
