An allied health major prepares you for healthcare careers that fall outside of medicine and nursing. It’s a broad field, covering everything from diagnostic imaging and respiratory therapy to healthcare administration and rehabilitation. Allied health professionals make up an estimated 60% of the U.S. healthcare workforce, making this one of the largest and most varied paths into the industry.
What “Allied Health” Actually Means
The term allied health refers to health professions that are distinct from medicine and nursing. Where doctors and nurses focus primarily on diagnosing and treating illnesses, allied health professionals tend to specialize in prevention, recovery, and diagnostic support. A physical therapist assistant helping someone regain mobility after surgery, a sonographer capturing images of a developing fetus, or a lab scientist analyzing blood samples are all allied health roles.
Some allied health professionals work closely with physicians as part of a care team. Others, like audiologists or dietitians, often work more independently. The common thread is deep expertise in a specific area of patient care or health systems rather than the broad clinical scope of a physician or nurse.
What You Study in the Major
Allied health programs typically begin with a strong science foundation. Expect to take anatomy and physiology (often a two-semester sequence), medical terminology, first-year composition, and quantitative reasoning or statistics in your first two years. These prerequisites give you the biological and communication skills that every allied health career requires.
After that foundation, the major branches into concentrations. At the University of Connecticut, for example, the allied health sciences bachelor’s degree offers four tracks: Health Sciences, Healthcare Administration, Public Health and Health Promotion, and Occupational and Environmental Health and Safety. Other programs may offer concentrations in areas like diagnostic sciences, medical laboratory science, or rehabilitation studies. The specific options vary by school, so the program you choose will shape your career direction significantly.
Some specializations require post-baccalaureate certificates or graduate training. Diagnostic genetic sciences and medical laboratory sciences, for instance, may involve additional certificate programs after your bachelor’s degree. If you’re eyeing a specific career like occupational therapy or physical therapy, your undergraduate allied health coursework often serves as the stepping stone to a required graduate program.
Concentrations and Career Paths
The range of careers under the allied health umbrella is genuinely wide. Here are some of the most common paths and what they pay:
- Dental Hygienist: Cleans teeth, screens for oral disease, and educates patients on dental care. Median salary of $94,260 per year.
- Diagnostic Medical Sonographer: Uses ultrasound equipment to create images that help physicians diagnose conditions. Median salary of $89,340.
- Radiologic or MRI Technologist: Performs X-rays, CT scans, or MRIs. Median salary of $78,980.
- Occupational Therapy Assistant: Helps patients develop or recover daily living and work skills under an occupational therapist’s guidance. Median salary of $66,050.
- Physical Therapist Assistant: Works with patients on exercises and treatments to improve mobility and manage pain. Median salary of $60,050.
These are May 2024 figures from the Bureau of Labor Statistics. Other allied health careers include respiratory therapists, clinical laboratory technologists, dietitians, speech-language pathology assistants, and health information technicians. The field also extends into non-clinical roles like healthcare administration and public health, which focus on managing health systems or improving community health outcomes rather than working directly with patients.
Job Growth in Allied Health
Healthcare occupations overall are projected to grow much faster than average from 2024 to 2034, according to the Bureau of Labor Statistics. An aging population needing more diagnostic testing, rehabilitation, and preventive care drives much of that demand. Allied health roles are particularly well positioned because they handle the specialized, hands-on work that can’t easily be automated or consolidated.
The variety within allied health also gives you flexibility. If one area of healthcare contracts or shifts, you have adjacent fields you can pivot toward, especially with a broad undergraduate foundation. Students who earn a general allied health sciences degree and later specialize through certificates or graduate work can adapt their career as the market evolves.
How It Differs From Pre-Med or Nursing
If you’re weighing an allied health major against pre-med or nursing, the distinction comes down to scope and timeline. Pre-med is not a major itself but a set of prerequisites for medical school, which adds four years of graduate education plus residency. Nursing programs lead to a specific license (RN or BSN) with broad patient care responsibilities across settings.
Allied health, by contrast, trains you in a focused specialty. You’ll know one area deeply rather than managing a patient’s overall care plan. Many allied health careers are accessible with a bachelor’s degree or even an associate degree, though some (like occupational therapy or audiology) require graduate training. For students who want to work in healthcare without the decade-long commitment of becoming a physician, allied health offers a faster and more targeted route into the field.
Choosing the Right Program
Not all allied health programs are structured the same way. Some universities offer a general allied health sciences degree that keeps your options open, letting you choose a concentration later or apply to graduate programs in specific disciplines. Others are more prescriptive, funneling you into a particular career track from the start.
If you already know you want to be a sonographer or a respiratory therapist, look for programs with clinical rotations or partnerships with hospitals in that specialty. If you’re less certain, a broader program with multiple concentrations gives you time to explore. Either way, check whether the program’s graduates are eligible for the licensure or certification exams your target career requires. In allied health, professional credentials matter as much as the degree itself, and not every program prepares you for every credential.
