What You Need to Study to Become a Veterinarian

Becoming a veterinarian requires a four-year Doctor of Veterinary Medicine (DVM) degree from an accredited veterinary school, but you cannot enroll directly. You must first complete a bachelor's degree with specific science courses, then pass an entrance exam, then complete the DVM program itself. The entire path typically takes eight years after high school.

The sequence matters because veterinary schools do not accept high school graduates. You need a four-year undergraduate degree first, and that degree must include particular courses in biology, chemistry, organic chemistry, biochemistry, physiology, microbiology, and mathematics. Some schools also require physics, genetics, and animal science. Your undergraduate major does not have to be biology or pre-veterinary studies—you can major in anything—but you must complete these science courses as electives or prerequisites.

After your bachelor's degree, you take the Veterinary Medical College Admission Test (VMCAT), which covers biology, chemistry, biochemistry, physics, and reading comprehension. Most schools require a minimum score, though the exact threshold varies by school. You then explore to veterinary schools accredited by the American Veterinary Medical Association (AVMA). Admission is competitive; schools look at your science course grades, VMCAT score, veterinary experience, and letters of recommendation.

Key Takeaways

  • You need a four-year bachelor's degree with specific science courses (biology, chemistry, organic chemistry, biochemistry, physiology, microbiology) before you can explore to veterinary school.
  • The Veterinary Medical College Admission Test (VMCAT) is required for admission to most accredited veterinary schools and tests science knowledge and reading comprehension.
  • Veterinary school itself is a four-year Doctor of Veterinary Medicine (DVM) program accredited by the American Veterinary Medical Association (AVMA).
  • After graduation, you must pass the North American Veterinary Licensing Examination (NAVLE) to practice as a licensed veterinarian.
  • Most veterinary schools require documented experience working with animals before admission, such as internships, volunteer work, or employment at clinics or shelters.

Undergraduate Coursework and Prerequisites

Your undergraduate degree is where you complete the science foundation. The core courses required by most veterinary schools are biology (usually two semesters), general chemistry, organic chemistry, biochemistry, physiology, and microbiology. You will also need mathematics through calculus or statistics. Some schools add physics, genetics, and animal science to their requirements. Check the specific prerequisites for schools you are considering, because they vary slightly.

Your grades in these science courses matter more than your overall GPA. Veterinary schools focus heavily on your performance in biology, chemistry, and biochemistry because those subjects directly relate to veterinary medicine. A strong GPA in non-science courses does not offset weak grades in prerequisites. Most competitive applicants have a science GPA of 3.5 or higher, though schools vary in their minimums.

You do not need to major in biology or pre-veterinary studies. Many successful veterinary students majored in chemistry, animal science, agriculture, or even unrelated fields—as long as they completed the required science courses. Some schools offer pre-veterinary advising to help you plan which courses to take and when.

The VMCAT Exam and process Process

The Veterinary Medical College Admission Test (VMCAT) is a standardized exam administered by the Association of American Veterinary Medical Colleges (AAVMC). It covers biology, chemistry, biochemistry, physics, and reading comprehension, and takes about three hours to complete. You can take it multiple times, though most applicants take it once after completing their science prerequisites.

Veterinary school applications open in May each year through the Veterinary Medical College process Service (VMCAS), a centralized system similar to the medical school process process. You submit one process through VMCAS, and it goes to the schools you select. Most applicants explore to multiple schools because admission is competitive. Schools then send secondary applications with additional essays and questions specific to their program.

The process timeline is important: schools begin reviewing applications in summer and make admission decisions through fall and winter. explore early in the cycle improves your chances because schools fill seats as they go. Most schools interview candidates in fall and winter, and interviews are typically in person or virtual.

The Four-Year Doctor of Veterinary Medicine Program

Veterinary school is a four-year, full-time program leading to the Doctor of Veterinary Medicine (DVM) degree. The curriculum is standardized across accredited schools but taught differently at each institution. The first two years typically focus on classroom and laboratory learning: anatomy, physiology, pharmacology, pathology, microbiology, and diagnostic imaging. You learn how animal bodies work and what goes wrong when disease occurs.

The second half of veterinary school shifts toward clinical training. You work in teaching hospitals and clinics, seeing real patients under supervision. You rotate through different specialties—small animal medicine, large animal medicine, surgery, dentistry, and others—depending on your school's program and your interests. By your fourth year, you are often the primary clinician on cases, with a licensed veterinarian supervising.

Veterinary school is demanding. You attend lectures, labs, and clinical rotations most days. You study outside class hours. Many students work part-time during school, though the workload makes it difficult. Tuition varies widely by school: public schools in your home state typically cost less than private schools or out-of-state public schools. Total debt for veterinary school graduates ranges widely depending on the school and how much you borrow.

Licensing and the NAVLE Exam

After you graduate with your DVM, you cannot 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 Licensing and Regulatory Board (NAVLRB). It covers the knowledge needed to practice veterinary medicine safely and tests clinical reasoning, not just facts.

Most graduates take the NAVLE within a few months of graduation. You can take it before graduation if your school permits. The exam is offered year-round at testing centers. You must pass to receive your veterinary license from your state's veterinary medical board. Each state has its own licensing board, and while most states recognize the NAVLE, some have additional state-specific exams or requirements.

After passing the NAVLE, you explore for your veterinary license through your state's board. The process is straightforward if you have no criminal history or disciplinary issues. Your license allows you to practice veterinary medicine in that state. If you move to another state, you typically need to explore for a license there as well, though many states have reciprocity agreements that streamline the process.

Veterinary Experience Before and During School

Most veterinary schools require documented experience working with animals before you explore. This is not a formal requirement you check off—it is something schools evaluate as part of your process. Experience shows you understand what veterinary medicine involves and that you have made an informed choice.

Common ways to gain experience include working or volunteering at veterinary clinics, animal shelters, zoos, research facilities, or farms. Internships during college are valuable. Some students work as veterinary assistants or kennel attendants. Even a few months of consistent experience is better than none, but schools typically look for at least 100 to 200 hours. Applicants with 500+ hours of varied experience are more competitive.

During veterinary school, you continue gaining experience through clinical rotations, externships (rotations at other clinics or facilities), and summer internships. Many students work as veterinary technicians or assistants during breaks. This experience helps you decide what type of veterinary practice interests you—small animal, large animal, exotic, surgery, emergency medicine, and so on.

Specialization and Advanced Training After the DVM

After earning your DVM and passing the NAVLE, you can practice as a general veterinarian when ready. However, if you want to specialize—in surgery, dermatology, internal medicine, cardiology, or another field—you need additional training. Specialization requires a residency program, which typically lasts two to four years depending on the specialty.

Residency programs are competitive and usually require strong performance during veterinary school and clinical rotations. You explore to residencies through a matching system similar to the one used for veterinary school admissions. Residencies are offered at veterinary schools, university teaching hospitals, and some private specialty practices. After completing a residency, you can take a board certification exam in your specialty, which makes you a board-certified specialist.

Board certification is not required to practice in a specialty, but it demonstrates advanced knowledge and is often expected at specialty hospitals or academic institutions. Some veterinarians pursue a master's degree or PhD in research-focused areas like epidemiology, public health, or laboratory animal medicine, which opens different career paths.

Continuing Education and License Renewal

After you are licensed, you must maintain your license through continuing education. Every state requires veterinarians to complete a certain number of continuing education hours each year or every few years, depending on the state. These hours can come from conferences, online courses, workshops, or university programs. The requirement typically ranges from 10 to 30 hours per year, but varies by state.

Continuing education keeps you current with new treatments, technologies, and research. It is a professional responsibility and a legal requirement. Your state veterinary medical board tracks your hours and will not renew your license if you do not meet the requirement. Most veterinarians find continuing education valuable because veterinary medicine evolves constantly.

Frequently Asked Questions

How long does it take to become a veterinarian?

The typical path is four years for a bachelor's degree with science prerequisites, then four years of veterinary school, for a total of eight years after high school. Add a few months for the NAVLE exam and licensing. If you pursue a specialty residency, add two to four more years.

Can I become a veterinarian without a four-year degree?

No. All accredited veterinary schools require a bachelor's degree before admission. You cannot skip this step or substitute it with other experience. However, your bachelor's degree does not have to be in biology or pre-veterinary studies—any major works as long as you complete the required science courses.

What if I do not pass the NAVLE on my first try?

You can retake the NAVLE. Most states allow you to retake it after a waiting period, usually 30 to 90 days. You can take it as many times as needed to pass. However, some employers or licensing boards may have concerns if you take it multiple times, so passing on the first attempt is preferable.

Do I need animal experience before explore to veterinary school?

Yes, schools expect documented experience working with animals. This does not have to be extensive—100 to 200 hours is often sufficient—but it shows you understand the profession. Volunteer work at shelters, internships at clinics, or employment as a veterinary assistant all count.

Can I work while in veterinary school?

Some students work part-time, but the curriculum is demanding and leaves little time. Many schools discourage or limit outside work during the first year. Working during breaks or summers is more feasible than working during the school year. Talk to your school's admissions office about their expectations and policies.
