|---|---|---|---|
| Associate of Applied Science (AAS) | 2 years | AVMA-CVTEA | VTNE |
| Bachelor of Science (BS) | 4 years | AVMA-CVTEA | VTNE |
| Online + Clinical Hybrid | 2–3 years | AVMA-CVTEA | VTNE |
| Military Experience Conversion | Varies | AVMA-CVTEA | VTNE |
Prerequisite Courses Before Admission
Before entering a veterinary technology program, you will need to complete specific prerequisite courses to ensure you are academically prepared. These usually include college-level biology, chemistry, and mathematics, along with strong communication skills.
Common Prerequisite Subjects
Most schools expect one or two semesters of each subject, so planning ahead prevents delays in starting core veterinary courses.
Core Veterinary Science Courses
Core courses provide the scientific foundation required to understand animal health, disease processes, and clinical procedures. They blend lecture knowledge with supervised laboratory practice.
Anatomy and Physiology
Detailed study of mammalian organ systems, emphasizing species differences and clinical relevance for diagnostics and nursing care.
Pharmacology and Medical Nursing
Covers drug calculations, administration routes, anesthesia monitoring, and postoperative pain management for companion animals.
Clinical Laboratory and Diagnostic Imaging
These courses train you to perform and interpret diagnostic tests, from bloodwork to advanced imaging, under veterinary supervision.
Clinical Pathology
Hands-on work with hematology, urinalysis, and microbiology to identify abnormalities and support accurate diagnosis.
Diagnostic Imaging and Radiology
Instruction in positioning, safety, and interpretation of radiographs, ultrasound, and other imaging modalities used in daily practice.
Practical Externship and Soft Skills
Externship rotations expose you to real-world clinics, allowing you to apply classroom knowledge while developing communication, teamwork, and ethical judgment.
You will practice patient restraint, sample collection, surgical preparation, and client education under the guidance of licensed veterinarians and seasoned technicians.
Key Steps to Becoming a Vet Tech
FAQ
Reader questions
What math and science prerequisites do most schools require?
Biology, college algebra or statistics, and often general chemistry with lab are standard prerequisites for admission into veterinary technology programs.
Do I need animal experience before applying to vet tech programs?
Many programs prefer or require volunteer or work experience with animals to ensure you understand the role and are committed to the field.
Can I complete the core courses online if I have a busy schedule?
You can take theory courses online, but clinical labs and externships must be completed in person at approved sites near you.
How long does it typically take to finish the required courses and graduate?
An Associate degree usually takes two years, while a Bachelor of Science often requires four years, including general education and clinical rotations.
