What’s on the VTNE? Domain Breakdown for Veterinary Technicians (2026)
As of September 2026, the Veterinary Technician National Examination (VTNE) tests candidates across 10 content domains defined in AAVSB’s VTNE Content Outline, approved by the AAVSB Board of Directors in March 2023 and unchanged since. The exam is 170 questions total: 150 scored plus 20 unscored pretest items that AAVSB embeds to build future exam forms and that you cannot identify while testing, delivered in a single 3 hour, computer based sitting with four answer choices per question and one correct answer. Animal Care and Nursing is the largest domain at 20% of scored items (30 questions), followed by Pharmacy and Pharmacology, Surgical Nursing, and Anesthesia, each at 13% (20 questions apiece). Communication and Veterinary Professional Support Services is the smallest domain at 5% (7 questions). Scores are reported on a scaled range of 200 to 800, with a passing scaled score of 425; AAVSB states plainly that it does not report VTNE results as a percentage or number correct. Here is exactly what falls under each of the 10 domains, how much weight each one carries, and what a sample question looks like.

The 10 VTNE Content Domains
AAVSB weights each domain by how much of a veterinary technician’s actual job it represents, not evenly. The chart below shows each domain’s share of the 150 scored questions, from Animal Care and Nursing at 20% down to Communication and Veterinary Professional Support Services at 5%.
What Each Domain Actually Covers
Animal Care and Nursing, the largest single domain, spans routine patient handling, nutrition, husbandry, and general nursing care across species. Pharmacy and Pharmacology covers calculating and preparing dosages, drug classifications and their effects, and safely storing and disposing of pharmacological, chemical, and biological agents. Surgical Nursing covers preparing the surgical environment and instruments, functioning as a sterile or circulating technician, and maintaining aseptic technique before, during, and after procedures. Anesthesia covers pre-anesthetic patient assessment, monitoring vital signs under anesthesia, and recognizing and responding to complications at every stage of a procedure.
Laboratory Procedures covers collecting, handling, and running in-house diagnostic samples, interpreting normal versus abnormal results, and maintaining lab equipment and quality assurance. Dentistry covers oral examination, cleaning, and charting procedures along with the safe use of dental equipment. Emergency Medicine / Critical Care covers triage, emergency nursing procedures, and monitoring a patient’s status through an emergency or critical episode. Pain Management / Analgesia covers assisting in developing and carrying out a pain management plan appropriate to the patient and procedure. Diagnostic Imaging covers positioning, equipment use, and quality assurance for radiography and related imaging modalities. Communication and Veterinary Professional Support Services, the smallest domain, covers client education and professional communication within the veterinary team.
How the VTNE Is Scored
Your raw performance on the 150 scored questions is mathematically converted to a scaled score between 200 and 800, and you need a 425 to pass. AAVSB does not report scores as a percentage correct or a raw number correct, so there is no “you got X out of 150” figure available to candidates; the scaled score is the only number that matters, and it is designed to represent the same passing standard across every administration and every version of the exam. Each of the four answer choices per question offers one clearly correct answer, there is no penalty for guessing, and you can skip, revisit, or flag questions for review within your 3 hour window. Because the 20 unscored pretest items are mixed in and indistinguishable from scored items, treating every question with equal attention is the only reliable strategy.
Because the outline weights domains by how large a share of a working veterinary technician’s actual duties they represent, the exam mirrors day-to-day practice more than a chapter-by-chapter textbook review would. A candidate strong in one or two domains but thin on others is exposed proportionally to how much weight that domain carries: a gap in Animal Care and Nursing, at 20% of scored items, matters more to your final scaled score than an equivalent gap in Communication and Support Services, at 5%. Studying in roughly the proportions AAVSB assigns each domain, rather than spending equal time on all 10, lines your preparation up with how the exam is actually built.

Frequently Asked Questions
How many domains does the VTNE cover?
10. AAVSB’s VTNE Content Outline, approved by the Board of Directors in March 2023, organizes the 150 scored questions into 10 weighted domains ranging from 5% to 20% of the exam.
Which VTNE domain has the most questions?
Animal Care and Nursing, at 20% of scored questions (30 of 150). Pharmacy and Pharmacology, Surgical Nursing, and Anesthesia are tied for second, each at 13% (20 questions apiece).
Does the VTNE include unscored questions?
Yes. Of the 170 total questions, 150 are scored and 20 are unscored pretest items AAVSB uses to build future exam forms. You cannot tell which items are pretest while testing.
What score do I need to pass the VTNE?
A scaled score of 425 on AAVSB’s 200 to 800 point scale. AAVSB does not report results as a percentage or raw number correct, only the scaled score.
