Health Science Degree vs. Biology Degree

By Elizabeth West (BA 26)

Are you struggling to decide between a health science degree and a biology degree? How do you decide which is best for you and your career goals? Because these programs are similar, it can be difficult to choose a major that sets you up for success. To make your decision easier, start by learning the differences between the two programs. 

Health Science Degree

What is health science? Health science is the study of life and health, generally for the purpose of healthcare. Biology, ecology, and physics are foundational classes in this major. Health science majors are equipped with the mathematical and scientific skills for medical careers in a variety of fields. In this major, you’ll be prepared to pursue graduate training and become a physician, a dentist, a veterinarian, or any of a number of healthcare specialties.

A health science major focuses on preparation for a specific medical career, like physician, physical therapist, physician assistant, and many others. A health science major will have advising and course content necessary for meeting program prerequisites and standardized exam expectations. Grace College also offers concentrations that can lead you to be a doctor, a veterinarian, an optometrist, or hold any number of health science jobs.

After graduating with a health science degree, you’ll be able to continue your education at a graduate institution, leading to a medical career in your chosen field and expertise. If you choose not to pursue graduate studies, you’ll still be equipped for a variety of life science jobs, such as laboratory work, medical sales, or even life science education. 

Biology Degree

What is biology? Similar to health science, a biology major studies life and what makes up a living organism. However, a biology major focuses more broadly on the organisms themselves and their biological processes rather than focusing on healing and healthcare. 

Biology majors begin with core biology classes and labs to learn the basics of biological structures and processes, incorporating not only classroom study but also hands-on lab work ranging from dissections to polymerase chain reaction experiments. Then, you’ll dive into genetics and specialized courses, such as microbiology or developmental biology. At Grace, you can choose from concentrations like general biology, neurobiology, environmental biology, or even medical sales

A biology program prepares you for work in everything from medical research to marine biology. Some career options may require a graduate-level education, such as those in biomedical engineering or medical technology. 

What’s the Difference?

When you’re considering a health science degree and a biology degree, the main difference is that health science is crafted specifically for students wanting to go into medical school. However, according to Dr. Rick Roberts, Grace’s pre-health professions coordinator and associate professor of biology, “Pretty much any job you can get with a biology degree, you will be able to get with a health science degree.” 

Grace’s health science program is streamlined to help you build up your graduate school application. For example, you’ll have time to pursue a minor outside of health science to diversify your application and make you stand out from other students. In this blog, Roberts provides tips for graduate school success and other advice for those pursuing a health science degree. 

At Grace, we also regularly survey graduate school qualifications to ensure we’re equipping our students to move forward in their education. With a health science degree, you’ll be specifically prepared for healthcare with tailored courses that meet graduate medical education requirements. As you move into your higher education, we will support you, and 90% of Grace’s health science graduates are accepted to graduate programs. 

Compared to health science, biology is considered a broader major with a wider spectrum of classes. Since biology may not have all the prerequisites you need to qualify for medical school, it is recommended that you set your career goals early and check your class schedules. For example, Grace’s biology major requires only one physics class, whereas two physics courses are required for medical or dental school. If you are a biology major planning to attend medical school, discussing specific degree requirements with your academic advisor is important for meeting the necessary prerequisites. 

For those questioning whether health science or biology is best for them, Grace’s first-year classes for a health science degree are designed to overlap with those for biology and environmental biology degrees. This allows you to shift from health science to biology (or vice versa) more smoothly if you discover your degree isn’t a good fit. 

“This gives students the chance to explore, learn, and see how they’re doing in classes to be able to make the best choice for their degree and concentration,” says Roberts. “We’ve certainly had students switch from one concentration to another, and this can be done even without transfer credits in three years.” 

Faith Integration 

Most importantly, at Grace College, we integrate our faith in Christ into all our programs. Our health science degree and our biology degree both dive into God’s complex Creation, whether they are observing His fingerprints while studying the human body in chemical interactions. Every class points to God as the Creator and our responsibility to steward His creation.

“We not only see creation as reflecting God, but we also take a step further and ask, ‘How does that impact our decisions now and down the road in a healthcare career?’” says Roberts.

In the end, whether you choose to pursue a degree in health science or biology, you’ll develop a deeper understanding of God’s intricate design in all living things. Both programs equip you with the scientific and analytical skills to thrive in your chosen field, with health science particularly crafted for medical school.
