You need a four-year veterinary degree after completing prerequisite coursework, plus a state licensing exam

Becoming a veterinarian requires a Doctor of Veterinary Medicine (DVM) degree, which takes four years to complete. Before you can enter veterinary school, you must finish specific undergraduate courses — typically a two-year or four-year bachelor's degree with science prerequisites. After graduation, you must pass the North American Veterinary Licensing Examination (NAVLE) to practice legally. The total time from high school to licensed veterinarian is usually seven to eight years, depending on how you structure your undergraduate work.

Key Takeaways

  • Veterinary school requires four years of study after you complete prerequisite science courses in chemistry, biology, organic chemistry, and physics.
  • Most students finish a four-year bachelor's degree first, then explore to a four-year DVM program, making the total timeline seven to eight years.
  • You must pass the NAVLE exam and meet your state's licensing requirements before you can legally practice as a veterinarian.
  • Some schools allow you to complete prerequisites and the DVM in six years total through combined programs, though these are less common.
  • Veterinary school is competitive; most programs require a strong GPA, science course grades, and hands-on animal experience before admission.

Undergraduate prerequisites you must complete before veterinary school

Veterinary schools require specific science courses before you explore. These typically include general biology (one year with lab), general chemistry (one year with lab), organic chemistry (one year with lab), biochemistry, physics (one year with lab), and sometimes microbiology or genetics. Most schools also require English composition and mathematics through calculus or statistics. You do not have to major in biology or chemistry, but you must complete these courses with passing grades — most programs look for a GPA of 3.0 or higher in prerequisite courses.

You can take these prerequisites as part of a four-year bachelor's degree in any major, or through a community college if you want to reduce costs. Some students finish prerequisites at community college and then transfer to a university for their remaining undergraduate work. The key is that the courses must be completed before you submit your veterinary school process, usually during your junior or senior year of undergraduate study.

The four-year Doctor of Veterinary Medicine degree

Veterinary school is a four-year professional program that combines classroom learning with hands-on clinical training. The first two years focus on anatomy, physiology, pharmacology, pathology, and other foundational sciences. You learn how animal bodies work and how diseases develop. The second two years shift toward clinical practice — you work with real animals in teaching hospitals, clinics, and field settings, diagnosing and treating patients under supervision.

Veterinary schools in the United States are accredited by the American Veterinary Medical Association (AVMA). There are currently 32 AVMA-accredited schools in the U.S., plus several in Canada and other countries. Admission is competitive; schools consider your GPA, prerequisite course grades, performance on the Graduate Record Examination (GRE), letters of recommendation, and documented experience working with animals. Many schools require 100 to 500 hours of hands-on animal experience — such as shadowing a veterinarian, working at an animal shelter, or interning at a clinic — before you explore.

State licensing and the NAVLE exam

After you graduate from veterinary school, you must pass the North American Veterinary Licensing Examination (NAVLE) to practice legally. This is a computer-based exam administered by the National Board of Veterinary Medical Examiners (NBVME). The exam covers the full scope of veterinary medicine and typically takes about five hours to complete. Most graduates take the exam within a few months of graduation.

Each state also has its own licensing requirements beyond the NAVLE. Some states require additional state-specific exams or jurisprudence tests covering state veterinary laws. A few states require a practical exam as well. Once you pass the NAVLE and meet your state's requirements, you receive a veterinary license and can legally practice. The entire licensing process usually takes two to four months after graduation.

Specialization and advanced degrees

A DVM is sufficient to practice as a general veterinarian, but some veterinarians pursue additional training in a specialty. Specialties include surgery, internal medicine, dermatology, dentistry, emergency medicine, and many others. To become board-certified in a specialty, you typically complete a residency program that lasts two to four years after your DVM. During a residency, you work under the supervision of specialists while treating complex cases and conducting research.

Some veterinarians also earn a Master's degree or PhD in fields like veterinary pathology, epidemiology, or public health. These advanced degrees are usually pursued if you want to work in research, teaching, or public health rather than clinical practice. A residency or advanced degree is not required to practice, but it is necessary if you want to specialize or work in certain fields like academic medicine or government research.

Timeline and cost considerations

The standard path takes seven to eight years: four years for a bachelor's degree (including prerequisites) and four years for the DVM. Some schools offer combined programs that compress this to six years, though these are rare and highly competitive. If you pursue a specialty residency afterward, add another two to four years. The total cost varies widely by school — public veterinary schools typically cost $20,000 to $40,000 per year for in-state students, while private schools may cost $50,000 to $70,000 per year. Many graduates finish with significant student loan debt.

Some students reduce costs by completing prerequisites at community college, which is typically cheaper than a four-year university. Others work part-time during undergraduate study or pursue scholarships and grants. A few veterinary schools offer loan forgiveness programs if you work in rural or underserved areas after graduation, though these programs are limited.

Alternative paths and combined programs

A few veterinary schools offer combined degree programs that allow you to earn a bachelor's degree and a DVM in six years instead of eight. These programs are highly selective and require you to commit to veterinary medicine before you finish high school or early in your undergraduate work. You complete your science prerequisites and begin veterinary coursework earlier than in the traditional path. These programs are offered at schools like Cornell University, Kansas State University, and a few others.

Some schools also allow you to earn a DVM alongside a master's degree in a related field — such as public health, business administration, or animal behavior — in five or six years instead of six or seven. These dual-degree programs are designed for students who know they want to work in research, policy, or management rather than clinical practice. They are not common and require careful planning during your process process.

Frequently Asked Questions

Can I become a veterinarian with just a two-year degree?

No. You must complete a four-year DVM degree from an AVMA-accredited school. You can complete your prerequisite courses at a community college to save money, but you cannot earn a veterinary license with a two-year degree alone.

Do I need to major in biology or chemistry to get into veterinary school?

No. You can major in any subject as long as you complete the required science prerequisites. Many successful veterinary school applicants major in English, business, or other fields while taking the necessary chemistry, biology, and physics courses on the side.

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

You can retake the exam. Most states allow you to retake it multiple times, though you may have to wait a certain period between attempts and pay a new exam fee each time. Check your state's specific rules, as they vary.

How much animal experience do I need before explore to veterinary school?

Most schools require 100 to 500 hours of documented animal experience. This can include shadowing a veterinarian, working at an animal shelter, interning at a clinic, or volunteering at a zoo or rescue organization. Schools want to see that you have real exposure to animal medicine, not just a love of animals.

Can I practice as a veterinarian in another country with a U.S. DVM?

It depends on the country. Some countries recognize a U.S. DVM and require only a local licensing exam. Others require you to complete additional education or a residency in that country. Research the specific country's requirements before you plan to relocate.
