What You Need to Study to Become a Vet

To become a licensed veterinarian in the United States, you need a Doctor of Veterinary Medicine degree (DVM or VMD) from an accredited veterinary school, plus a passing score on the North American Veterinary Licensing Examination (NAVLE). Most veterinary schools require four years of study after you finish your bachelor's degree. Before you explore to veterinary school, you'll need to complete specific undergraduate courses in biology, chemistry, and other sciences—usually two to three years of coursework.

The path is long and structured. You cannot skip the undergraduate science requirements or the four-year DVM program. After graduation, you must pass the NAVLE before you can practice. Some states also require additional exams or a state-specific veterinary license, but the NAVLE is the standard hurdle everywhere.

Key Takeaways

  • You must earn a bachelor's degree with specific science courses (biology, chemistry, organic chemistry, biochemistry, physics, and microbiology) before explore to veterinary school.
  • Veterinary school is a four-year Doctor of Veterinary Medicine (DVM or VMD) program offered only at accredited schools, of which there are 34 in the United States.
  • After graduation, you must pass the North American Veterinary Licensing Examination (NAVLE) to become licensed and practice as a veterinarian.
  • The entire process from starting your bachelor's degree to becoming licensed typically takes seven to eight years, depending on how quickly you complete your undergraduate work.

Undergraduate Science Requirements Before Veterinary School

Most veterinary schools require you to complete a bachelor's degree in any major, but you must take specific science courses during those four years. The core courses are biology (usually two semesters), general chemistry (two semesters), organic chemistry (two semesters), biochemistry, physics (two semesters), and microbiology. Some schools also require mathematics, genetics, and animal science courses. These prerequisites typically take two to three years to complete if you're taking them alongside other degree requirements.

You should check the prerequisites for the specific veterinary schools you're interested in, because requirements vary slightly. Some schools want additional courses in physiology, anatomy, or statistics. Taking these courses at a community college is acceptable to most veterinary schools, but you should verify this with the schools on your list before enrolling. Grades in science courses matter heavily—veterinary schools typically look for a GPA of 3.5 or higher in your science courses, though some schools accept lower grades if your overall record is strong.

Beyond coursework, veterinary schools expect you to have hands-on experience with animals. This usually means working or volunteering at a veterinary clinic, animal shelter, farm, zoo, or research facility. Most successful applicants have 200 to 500 hours of veterinary experience before they explore. This experience shows schools that you understand what the job actually involves and that you're committed to the field.

The Four-Year Veterinary School Program

Veterinary school is a four-year professional degree program. The first two years focus on classroom and laboratory learning—anatomy, physiology, pharmacology, pathology, microbiology, and diagnostic imaging. You'll learn how animal bodies work, how diseases develop, and how to recognize problems on X-rays and ultrasounds. The second two years shift toward clinical work, where you diagnose and treat real animals under supervision in the school's teaching hospital.

All veterinary schools in the United States are accredited by the American Veterinary Medical Association (AVMA). There are 34 accredited schools across the country. Some are at state universities (like University of California, Davis, or Colorado State University), and some are private institutions. Admission is competitive—most schools receive thousands of applications for a few hundred spots. Your undergraduate GPA, science course grades, MCAT or GRE scores, veterinary experience, and personal statement all factor into decisions.

During your final year, you'll rotate through different specialties—small animal medicine, large animal medicine, surgery, dentistry, and others. This rotation helps you figure out what type of veterinary work interests you most. Some students know they want to work with dogs and cats in a private clinic; others want to work with horses, cattle, or exotic animals. The clinical rotations let you test these interests before you graduate.

Licensing and the NAVLE Exam

After you graduate from veterinary school, you cannot legally practice as a veterinarian until you pass the North American Veterinary Licensing Examination (NAVLE). This is a computer-based exam administered by the North American Veterinary Medical Education Accreditation (NAVMEA). Most graduates take it within a few months of finishing school. The exam covers the full scope of veterinary medicine—diagnosis, treatment, surgery, pharmacology, and professional responsibility.

The NAVLE is offered multiple times per year at testing centers across the country. You register through the NAVMEA website and pay a fee (currently around $600, though this may vary). Most graduates pass on their first attempt, but if you don't, you can retake it. Some states also require a state-specific veterinary license exam or jurisprudence exam in addition to the NAVLE, so check your state's requirements before you graduate.

Specialization and Advanced Training

After you're licensed, you can start working as a general practice veterinarian when ready. But if you want to specialize—in surgery, cardiology, dermatology, or another field—you'll need additional training. Specialization requires a residency program, which typically lasts two to four years depending on the specialty. Residencies are competitive and usually involve working at a university veterinary school or a specialty referral hospital while taking additional coursework and passing board exams in your specialty.

Some veterinarians pursue a master's degree or PhD in addition to or instead of a residency. These programs are useful if you want to work in research, public health, or teaching. A master's typically takes two years; a PhD takes four to six years. These advanced degrees are not required to practice as a veterinarian, but they open different career paths.

Timeline and Cost Considerations

The full path from high school to licensed veterinarian takes seven to eight years. Four years for your bachelor's degree, four years for veterinary school, and a few months to prepare for and pass the NAVLE. If you need to retake prerequisite courses or spend extra time building veterinary experience before explore to school, it could take longer.

Veterinary school is expensive. Tuition at state schools ranges from $15,000 to $30,000 per year for in-state students and $35,000 to $50,000 per year for out-of-state students. Private veterinary schools cost $40,000 to $60,000 per year. Most students graduate with significant student loan debt. Federal loans, private loans, and some scholarships are available, but you should research funding options early in your undergraduate years.

Frequently Asked Questions

Do I have to go to veterinary school in the United States?

No. If you attend veterinary school in another country, you can still practice in the United States, but you'll need to pass additional exams. The Educational Commission for Foreign Veterinary Graduates (ECFVG) administers exams for graduates of non-accredited schools. The process is more complex and takes longer than the standard NAVLE route, so most people attend U.S. schools if they plan to practice here.

Can I become a veterinarian with an associate degree instead of a bachelor's degree?

No. Veterinary schools require a bachelor's degree. You cannot explore to veterinary school with only an associate degree, even if you've completed all the science prerequisites. You must earn a four-year bachelor's degree from an accredited college or university.

What if I don't pass the NAVLE on my first try?

You can retake the exam. Most states allow you to retake it multiple times, though some limit the number of attempts or require waiting periods between attempts. You cannot practice as a veterinarian until you pass, so you'll need to work in a support role or find other work while you prepare to retake it.

Do I need to specialize, or can I just be a general practice vet?

You can absolutely work as a general practice veterinarian without specializing. Most veterinarians work in general practice at animal clinics, treating a wide range of animals and conditions. Specialization is optional and is only necessary if you want to focus on a specific area like surgery or cardiology.

How much do veterinarians make after they graduate?

Starting salaries vary by location, type of practice, and employer, but most new veterinarians earn between $60,000 and $90,000 per year. Experienced veterinarians and those who own their own practices often earn significantly more. Your actual earnings will depend on where you work and the choices you make throughout your career.
