What Is Health Science?

Health science is a multidisciplinary field that covers the broad spectrum of human and animal health. Health professionals can become researchers and educators who cultivate medical knowledge. They can also work in the applied sciences, using their knowledge and skills to cure diseases and improve individual and community health.

Due to the broad nature of online health science degrees, students can align their academic training with individual career goals through multifarious elective and concentration options. Healthcare administration is a popular option for undergraduate students; this degree track trains candidates to develop and manage healthcare programs and facilities. Health science students may also pursue a public health concentration, which prepares them for careers in environmental health, consumer advocacy, and infectious disease surveillance. Additional subfields include epidemiology, pharmacy technology, occupational therapy, and medical laboratory technology.

Healthcare occupations as whole continue to expand due to the needs of an aging U.S. population and shifting government regulations. The Bureau of Labor Statistics (BLS) projects a 14% growth in these careers between 2018 and 2028. That increase translates to nearly 2 million new jobs.

Expert Interview

Rafael Salazar II

Rafael Salazar II

Secretary at Fundación Manos Juntas

Rafael Salazar II is an occupational therapist (OT) and consultant. He received his master of health science from the Medical College of Georgia (now Augusta University) in 2012. Rafael has worked as a lead clinician in outpatient rehab settings and as a clinical consultant helping the state with hospital transitions. He serves on the state OT board and the board of directors for the National Board for Certification in Occupational Therapy (NBCOT).

Why did you choose to study health science? Was it something that always interested you?

chose to enter the health science field after spending the summer before my senior year in high school in an outpatient occupational therapy hand clinic. An accident led to me undergoing a tendon repair for my left thumb and nerve. I was at an interesting time in life -- right before my last year in high school, about to have to make big decisions about my future.

That experience made me realize that I wanted to work in a field where I would be able to help people overcome limitations, recover from injuries, and improve their overall health and well-being. That led me to pursue a master's in health sciences at the Augusta University (formerly MCG) School of Allied Health Sciences in the occupational therapy program.

I graduated from that program in 2012 with an MHS in occupational therapy. I spent some time working in long-term care, managing the OT caseload across a couple different skilled nursing facilities. From there, I moved to an outpatient specialty clinic at the Veterans Affairs (VA) Medical Center in Augusta, Georgia.

That experience gave me a few interesting opportunities, one of which was to receive some management and leadership development training. I picked up a lot of ancillary skills like project management, systems development, strategic planning, and the like. During that time, I was also able to serve on the state licensing board for OT in Georgia.

Those experiences acted as the platform that I used to jump into an exciting role as an independent consultant, working on a project with Georgia's Department of Behavioral Health and Developmental Disabilities -- helping transition individuals out of state hospitals into community residences.

Is it common for professionals in your field to work as consultants on top of their other roles? Why or why not? Would you recommend that health science students considering pursuing opportunities as consultants?

It can be common for professionals in this field to provide some consulting services -- usually around accessibility, equipment, and home modifications -- on a clinical basis. It's a little more rare for professionals in this field to find themselves working in management consulting. The reason for that is probably because falling into a clinical consulting role makes sense to most clinicians, so it tends to be the obvious choice.

In my situation, I had the benefit of having received training in project management, policy work, and strategic planning. Those skills and interests ended up opening the doors to start contracting and doing clinical consulting and merging that into a management consulting role.

Currently, I do both: I provide clinical consulting services as well as work on projects involving systems, policies, and procedures. I think I'd recommend that anyone consider working in consulting once they're in a position in their career to provide value through that service.

What I mean by that is this: You need to spend the first bit of your career gaining skills, expertise, and insights that you can then use as a consultant to help move the needle on behalf of your clients. Without putting the time in at the beginning, you won't have anything to offer in the way of consulting.

However, if you are able to develop deep expertise and skills, taking the leap into consulting can provide a lot of opportunities, from higher income to the possibility of doing it full time as a contractor or business owner.

What does professional development look like in your field?

Well, for occupational therapy, professional development is at some level dictated by the licensing agencies. This typically involves taking courses to gain continuing education units (CEUs) as part of licensure renewal. So for me, I am licensed in Georgia and certified nationally through NBCOT. So I have two licenses to keep up with, which involves gaining the appropriate number of CEUs in each category.

In reality, that's where most clinical professionals stop. They do what is required to maintain licensure and little else. I attribute much of my advancement and opportunities in my career to the fact that I have always looked to improve my professional skills not only in the clinical area but also in other advantageous fields. For example, I have taken courses and seminars on project management, business management, Excel, marketing, strategic planning, investing/finance, and customer service.

I've also made the commitment to myself to be a regular reader (my current goal is one book per month). I read books on business, personal finance, psychology, marketing, wellness/health, and entrepreneurship. All of that extra learning increases my knowledge base, improves my ability to draw insights from work situations and current events and apply those insights, knowledge, and skills in my work.

It doesn't matter where you find yourself in the health science field -- clinical work, research, policy development -- the skills and knowledge you gain from studying things outside of your particular area can pay great dividends, both in your personal life as well as your career and opportunities that present themselves.

What advice would you give to students considering earning a degree in health science?

I would give the advice I give every student: Whatever course of study you choose, whether it be clinical, academic, or administrative, never pigeonhole yourself in that narrow field. You will find as you go through your career that interesting opportunities abound in areas that might be just outside of your comfort zone and skill set.

Be courageous enough to grab ahold of those opportunities. If it means learning new skills, learn them. Do that, and you will look back at your career -- and life -- and be amazed at how making those decisions propelled you to achieve more than you would have thought possible or realistic if you simply had stayed put in your niche or specialization.

The world is full of people who wish they had taken their chance when it came by. Be sure you're not one of those people. You do that by always learning, growing, and -- at times -- making uncomfortable decisions that stretch you to the limit of your skills and abilities.

What advice would you give to students who are trying to decide whether to earn a health science degree online or on campus?

I think that would depend entirely on the degree or field being pursued. For example, if it is a clinically based degree (like rehabilitation), I would think you would need to spend some time on campus to learn those hands-on skills needed for assessment and treatment. If it is more about administration, management, or research, it may be cheaper and more convenient to earn that degree online.

Any final thoughts for us?

My last bit of advice would be to keep focused on what I call your "higher purpose." What I mean by that is the reason you chose to enter the career field you have selected. Why did you choose health science? What goal or aspiration that is above simply landing a steady job led you there? Focusing on that will make all of the work, study, tests, applications, and the like bearable.

There will be times when all you feel you are doing is studying things that you feel have no application to your field. You can feel like you're jumping through hoops to land your job or finish your degree. Without that higher purpose driving you on, it can be very easy to give up, quit, or settle for mediocrity.

How to Choose a Bachelor's in Health Science Program

Colleges and universities need to obtain national or regional accreditation to confer valid degrees. Higher education institutions become nationally accredited through authorities supported by the U.S. Department of Education and the Council for Higher Education Accreditation. They receive regional accreditation from one of six location-specific organizations.

Online health science degrees can earn specialized/programmatic accreditation from the Commission on Accreditation of Allied Health Education Programs. Accreditation bodies also exist for specialized programs, including the Council on Education for Public Health. By earning an accredited online bachelor's degree in health science, you ensure that the training you receive satisfies industry standards.

Here are some other important factors to keep in mind when choosing your program.

  • Tuition Price: By attending a school that offers low tuition rates, you minimize the burden of student loan debt. Distance education is a particularly cost-effective option. Many online health science degrees come with affordable per-credit tuition prices that ignore residency status.
  • Program Outcomes: Due to the broad nature of health science, you need to enroll in a bachelor's program that directly supports your professional goals, whether that be career entry or graduate academics. Consider factors like course offerings, concentrations, internship requirements, and networking opportunities.
  • Student Resources: The best postsecondary schools deliver one-on-one academic counseling, accessible tutoring services, and campus engagement opportunities. You should also explore prospective schools' career services, including assistance with resume building and job searching.
