NAVLE Exam Prep: Study Plan, Priority Map, and Starter Questions
Use the 12-week plan below as your base, then shrink it if your date is closer. It follows ICVA's 2026–2027 Candidate Handbook, including the switch to 12 blocks of 30 questions that started with the October–November 2026 window.
Your 12-week NAVLE study plan
Time assumptions: 5–6 study days a week, about 1.5–2.5 hours on rotation days and longer on days off. Every session starts with one or two timed 30-question mixed blocks (33 minutes each), followed by review of every miss. Weeks are weighted toward the species ICVA weights most.
| Week | Focus | Practice | Checkpoint |
|---|---|---|---|
| 1 | Baseline. Read the Candidate Handbook, download the Competency Domains and Species and Diagnoses outlines, start an error log | ICVA's free 20-question tutorial plus the 12 starter questions on this page | Apply during your window's application period if you haven't |
| 2–3 | Canine, system by system, plus toxicology | 1–2 timed blocks a day, mostly canine with some mixed | Every miss logged and revisited 2–3 days later |
| 4–5 | Feline, system by system, plus toxicology and behavior | 1–2 blocks a day, mostly feline, keep some canine in the mix | End of week 5: first ICVA Self-Assessment, standard-paced, to see where you stand |
| 6 | Equine | 1–2 blocks a day, half equine, half mixed | Re-sort your remaining weeks using the self-assessment breakdown |
| 7 | Bovine and herd health, including residue and extralabel drug rules | 1–2 blocks a day, half bovine | — |
| 8 | Porcine, ovine/caprine, camelid; foreign animal and reportable diseases | 1–2 mixed blocks a day | — |
| 9 | Small mammals, pet birds, poultry, reptiles, aquatics; public health and epidemiology | 1–2 mixed blocks a day | One full-length rehearsal: 12 blocks of 30, 33 minutes each, 50 minutes of total break time |
| 10 | Communication, professionalism, practice management; your two weakest areas from the error log | 2 mixed blocks a day | — |
| 11 | Mixed timed blocks only | 2–4 mixed blocks a day | Second full-length rehearsal |
| 12 | Taper and logistics | 1–2 mixed blocks a day; error-log review | Second ICVA Self-Assessment a few days before the exam; check your permit and ID name match |
ICVA doesn't publish a recommended study length. This is our editorial plan, built on ICVA's weights and format. It isn't a guarantee of a score.
Testing in March 2027?
The Handbook (p. 16) lists the March 2027 window as March 1–20, 2027, with applications December 1, 2026–January 7, 2027 and scores around April 19–May 3, 2027. For an appointment in the first week of March, Week 1 of this plan starts the week of December 7, 2026. Later appointment? Slide every week later by the same amount.

What to study first: the NAVLE priority map
Dogs and cats make up about half of the species target blueprint (49.9%). Add horses and cattle and those four species account for 77.9% of the target weighting. That makes them an efficient place to start, while the smaller species still belong in your plan.
| Species | ICVA target weight |
|---|---|
| Canine | 25.6% |
| Feline | 24.3% |
| Equine | 14.7% |
| Bovine | 13.3% |
| Porcine | 5% |
| Other small mammals | 3.3% |
| Ovine/caprine | 3.3% |
| Pet bird | 2.3% |
| Poultry | 2% |
| Non-species specific | 2% |
| Camelid/cervidae | 1.7% |
| Reptiles | 1.5% |
| Aquatics | 1% |
Weights come from the 2026–2027 Candidate Handbook, p. 25, and ICVA's Exam Blueprint. These are target blueprint weights, not a promise about the exact number of questions from a species on your individual form and not a rule that your study hours must match the percentages exactly.
The competency side matters just as much. Most of the exam asks what you'd find, conclude, or do next.
| Competency domain | Weight | Subdomains |
|---|---|---|
| Clinical Practice | 70% | Data Gathering and Interpretation 35%; Health Maintenance and Prevention 35% |
| Preventive Medicine and Animal Welfare | 15% | Animal Welfare 6%; Environmental Health and Safety 5%; Veterinary Public Health 4% |
| Communication | 8% | With clients 5%; with veterinary and other professionals 3% |
| Professionalism, Practice Management and Wellness | 7% | Practice Management 4%; Professional Development and Lifelong Learning 3% |
Use the Species and Diagnoses outline as your checklist of conditions by species and body system. ICVA says it lists examples, so the exam can include conditions that aren't on it. The Competency Domains outline lists the tasks behind each domain, from obtaining informed consent to reporting a transboundary disease. It also places epidemiology and biostatistics under Preventive Medicine.
How to run each study session
Every session follows the same loop:
- Do one timed block. 30 questions in 33 minutes, mixed or focused on the week's species.
- Review every miss and every guess. Sort each into one of three buckets:
- Knowledge gap: you didn't know the disease, drug, test, or rule.
- Reasoning gap: you knew the facts but missed the clue or chose the wrong priority.
- Pacing or nerve: you ran out of time, rushed, or changed a right answer without a reason.
- Repair only what the miss points to. Read the section on that one condition or rule, not the whole chapter.
- Write the rule from memory in one line.
- Retest it in 2–3 days with a new question or by recalling the rule without notes.
A worked error-log entry
Say you missed starter Question 4 below by choosing insulin alone.
| Question/topic | Why I missed it | Rule to remember | Revisit |
|---|---|---|---|
| Blocked cat, K 9.0, ECG changes | Reasoning gap: I went for lowering K and skipped protecting the heart | Calcium gluconate protects the heart within minutes but doesn't lower K; insulin needs dextrose; relieving the obstruction fixes the cause | Thursday |
Four columns are enough. The point is that each miss changes what you study next.
Pacing in 30-question blocks
33 minutes for 30 questions works out to 66 seconds per question on average. Treat that as a budget, not a rule. Some vignettes take 30 seconds, and a radiograph question may take two minutes. Within a block you can skip and flag questions, but once the block closes you can't go back (ICVA structure update). So flag, make a best guess, and move on rather than leaving blanks.
12 starter NAVLE-style questions
These are original, unofficial practice questions written by Castleport Test Prep. They are not NAVLE items. Each answer explains the reasoning and the source, so you can use it to decide what to review next. No image questions here, though about 15–20% of real NAVLE questions include photos or radiographs.
The set covers dogs, cats, horses, cattle, poultry, and a non-species epidemiology question. It has no swine, small ruminant, camelid, or exotic items, so don't read your score as a full-exam sample.
Question 1
Canine · Clinical Practice: Data Gathering and Interpretation
A 4-year-old spayed female standard poodle has had 3 weeks of on-and-off vomiting, diarrhea, and lethargy. She improved briefly after fluids and an antiemetic at another clinic. Today she is weak and about 7% dehydrated, with weak pulses and a heart rate of 64 beats/min. Results:
| Test | Result | Reference interval |
|---|---|---|
| Sodium | 129 mEq/L | 142–152 |
| Potassium | 7.4 mEq/L | 3.9–5.1 |
| BUN | 62 mg/dL | 8–28 |
| Creatinine | 2.1 mg/dL | 0.5–1.5 |
| Lymphocytes | 3,800/µL | 1,000–4,800 |
Which test is most appropriate to confirm the most likely diagnosis?
- A. Low-dose dexamethasone suppression test
- B. ACTH stimulation test measuring serum cortisol
- C. Urine specific gravity
- D. Serum fructosamine
- E. Abdominal ultrasound of the adrenal glands
Show answer and explanation, question 1
Answer: B. ACTH stimulation test.
The picture points to hypoadrenocorticism (Addison disease): waxing and waning GI signs, hyperkalemia with hyponatremia, a slow heart rate for a dehydrated dog, and a normal lymphocyte count when a sick, stressed dog would usually be lymphopenic. The Na:K ratio here is 129 ÷ 7.4 ≈ 17. A ratio under 27 suggests Addison disease but doesn't prove it. The ACTH stimulation test is the definitive test; a post-ACTH cortisol under 2 mcg/dL supports the diagnosis.
- A tests for hyperadrenocorticism (Cushing's), the opposite problem.
- C helps separate prerenal from renal azotemia but can't confirm adrenal failure.
- D is a diabetes test.
- E can support the diagnosis if the adrenals look small, but it doesn't confirm it.
In a real crisis you'd stabilize the dog first, including treating the hyperkalemia; this question only asks how to confirm.

Question 2
Canine · Preventive Medicine and Animal Welfare: Veterinary Public Health
A 5-year-old neutered male Labrador retriever with a documented, current rabies vaccination fought a raccoon in his yard last night. The raccoon ran off and can't be tested. The dog has a small muzzle wound. Under the 2016 NASPHV Compendium of Animal Rabies Prevention and Control, what is the recommended plan, subject to the local public health authority?
- A. Euthanize the dog and submit the head for rabies testing
- B. Give a rabies booster now and keep the dog under the owner's control and observation for 45 days
- C. Strict quarantine for 4 months
- D. No action, because the dog is currently vaccinated
- E. Observe the dog for 10 days
Show answer and explanation, question 2
Answer: B. Booster now, then 45 days of observation under the owner's control.
A raccoon that can't be tested counts as a suspect rabid animal, so the dog was exposed. Under the 2016 Compendium, a currently vaccinated dog that's exposed gets a booster right away and is observed for 45 days.
- A and C are the options the Compendium gives for dogs that have never been vaccinated: euthanasia, or vaccination plus a 4-month strict quarantine.
- D skips the booster, which the Compendium calls for even in vaccinated dogs.
- E is the 10-day confinement used for a healthy dog that bit a person, a different situation.
State and local rules can be stricter; Florida, for example, writes the 45 days as a quarantine.

Question 3
Canine · Clinical Practice: Health Maintenance and Prevention
A 7-year-old male Great Dane started retching without bringing anything up 2 hours after a large meal. His cranial abdomen is distended and drum-tight. Heart rate is 180 beats/min, mucous membranes are pale, capillary refill time is 3 seconds, and pulses are weak. A right lateral radiograph shows a large gas-filled stomach with the pylorus displaced dorsally and cranially, and a soft-tissue band dividing the gastric gas shadow. What is the most appropriate immediate management?
- A. Go straight to surgery before starting IV fluids
- B. Give metoclopramide and repeat radiographs in 6 hours
- C. Give IV crystalloids through large-bore cephalic catheters while decompressing the stomach, then correct the volvulus surgically once he is stabilized
- D. Place a saphenous catheter for fluids and monitor
- E. Perform a barium contrast study to confirm the diagnosis
Show answer and explanation, question 3
Answer: C. Fluid resuscitation and gastric decompression together, then prompt surgery.
This is gastric dilatation-volvulus (GDV). The displaced pylorus ("reverse C") and the band dividing the gas shadow ("double bubble") are the classic right lateral findings. He is in shock, so restoring circulating volume comes first, through large catheters in front-limb veins. Decompression by orogastric tube or trocarization happens alongside, and surgery follows quickly after stabilization, usually with a gastropexy to prevent recurrence.
- A sends an unstable dog to anesthesia in shock.
- B delays treatment of a condition where delay increases deaths.
- D uses a hindlimb vein, which Merck advises avoiding where possible in GDV.
- E adds nothing; the radiograph already shows the diagnosis.

Question 4
Feline · Clinical Practice: Health Maintenance and Prevention
A 3-year-old neutered male cat has been straining in the litter box for 36 hours. He is now lethargic, with a heart rate of 110 beats/min, a rectal temperature of 98.0 °F (36.7 °C), and a large, firm, painful bladder. Serum potassium is 9.0 mEq/L (reference interval 3.5–5.5). The ECG shows absent P waves and tall, peaked T waves. Which drug should be given first to protect the heart?
- A. 10% calcium gluconate, slow IV over 15–30 minutes, with ECG monitoring
- B. Furosemide IV
- C. Regular insulin IV without dextrose
- D. Atropine IV to correct the slow heart rate
- E. Prednisolone
Show answer and explanation, question 4
Answer: A. Calcium gluconate.
Severe hyperkalemia from urethral obstruction can cause life-threatening arrhythmias. Calcium gluconate acts within minutes to make heart muscle cells less excitable. It doesn't lower potassium. Insulin with dextrose shifts potassium into cells, but only temporarily. The definitive fix is relieving the obstruction, which lets the kidneys excrete potassium again.
- B doesn't protect the heart, and urine can't leave a blocked bladder.
- C can lower potassium, but insulin given without dextrose risks hypoglycemia, and it doesn't protect the heart right away.
- D treats the rate, not the hyperkalemia that's causing it.
- E has no role in hyperkalemia.

Question 5
Feline · Clinical Practice: Health Maintenance and Prevention
A 2-year-old indoor cat was found chewing the leaves of an Easter lily (Lilium longiflorum) about 1 hour ago. She vomited once and is otherwise bright, and her baseline creatinine is normal. What is the best plan?
- A. Send her home and recheck creatinine in 3 days if signs develop
- B. Give one dose of furosemide and send her home
- C. Give oral N-acetylcysteine and send her home
- D. No treatment, because only the flowers are toxic
- E. Start IV fluid diuresis for 48 hours and monitor kidney values and electrolytes
Show answer and explanation, question 5
Answer: E. Start 48 hours of IV fluid diuresis and monitor renal values.
True lilies (Lilium and Hemerocallis) can cause acute kidney injury in cats, and even small exposures can be dangerous. Current ASPCApro guidance calls for IV fluid diuresis for 48 hours with monitoring of renal values and electrolytes after exposure to a true lily. Timing is critical: if treatment starts more than about 18 hours after exposure, renal damage may be irreversible.
- A waits for azotemia, by which point the window may have passed.
- B is not a substitute for sustained fluid diuresis.
- C is the antidote for acetaminophen, not lilies.
- D is wrong; leaves, flowers, and even pollen can cause kidney injury.

Question 6
Feline · Communication: Communication with Clients
A client who is 10 weeks pregnant has two indoor-only cats fed commercial canned food. Her obstetrician mentioned toxoplasmosis, and she asks whether she has to give the cats up. What is the best advice?
- A. Rehome the cats until after the baby is born
- B. Start both cats on a preventive antibiotic
- C. Clean the litter box once a week so she handles it less often
- D. Keep the cats; have someone else clean the litter box every day (or wear disposable gloves and wash hands afterward), keep the cats indoors, and don't feed them raw meat
- E. Move the litter box outdoors
Show answer and explanation, question 6
Answer: D.
The CDC's message to pregnant cat owners is that they don't have to give up their cat. They should ask someone else to change the litter, or use gloves and wash thoroughly. Daily changing matters because Toxoplasma oocysts don't become infective until 1–5 days after they're shed. Keeping cats indoors and avoiding raw meat cuts the cats' own exposure.
- A is unnecessary, per the CDC.
- B isn't part of CDC prevention advice.
- C is backwards: weekly changes give oocysts time to become infective.
- E doesn't change who cleans the box or how often, which is what the CDC's advice is about.

Question 7
Equine · Clinical Practice: Data Gathering and Interpretation
A 24-hour-old Thoroughbred filly was born unassisted. The mare was dripping milk for two days before foaling, and the foal nursed poorly overnight. The filly is bright and alert. Serum IgG is 250 mg/dL. What is the best next step?
- A. Give 2 L of colostrum by nasogastric tube now and recheck tomorrow
- B. No treatment; recheck IgG in a week
- C. Give equine plasma IV, watching for a transfusion reaction
- D. Start oral antibiotics only
- E. Vaccinate the foal today
Show answer and explanation, question 7
Answer: C. IV equine plasma.
Merck defines complete failure of transfer of passive immunity as serum IgG under 400 mg/dL at 24 hours old, and partial failure as 400–800 mg/dL. At 250 mg/dL this filly has complete failure. Merck's guidance is to give IV equine plasma; one liter typically raises a 50-kg foal's IgG by 200–300 mg/dL, so 2–4 L may be needed. Start slowly and monitor for a reaction.
- A: Merck's colostrum guidance covers the first 12–18 hours. At 24 hours with complete failure, plasma is the recommended treatment.
- B leaves a foal with almost no antibody protection.
- D doesn't replace the missing immunoglobulin.
- E: vaccines don't fix the immediate gap in protection.

Question 8
Equine · Clinical Practice: Data Gathering and Interpretation
A 22-year-old pony gelding is examined in March. His long, curly coat failed to shed last spring, he had an episode of laminitis last month, and the owner says he drinks more than he used to. Which test is the most appropriate first step to diagnose the most likely condition?
- A. Resting (basal) plasma ACTH, compared with a season-specific reference interval
- B. Serum T4
- C. Muscle biopsy
- D. Rectal palpation
- E. Abdominal ultrasound
Show answer and explanation, question 8
Answer: A. Resting plasma ACTH.
An old pony that fails to shed and has laminitis fits pituitary pars intermedia dysfunction (PPID). Merck says diagnosis rests on resting endogenous ACTH or on evocative testing. ACTH rises naturally in the fall, so results must be compared with season-specific reference values.
- B: hypothyroidism doesn't explain this picture.
- C, D, and E don't diagnose PPID.
Review if you missed it: PPID signs and why ACTH testing depends on the season. Source: Merck Veterinary Manual, Hypertrichosis Associated With Adenomas of the Pars Intermedia in Horses.
Question 9
Bovine · Clinical Practice: Health Maintenance and Prevention
A 6-year-old Jersey cow calved 12 hours ago. She is down on her sternum and can't rise. Her head is tucked toward her flank, her ears are cold, her rectal temperature is 99.0 °F (37.2 °C), her heart rate is 92 beats/min, and her heart sounds are faint. What is the best treatment?
- A. Dexamethasone, then recheck tomorrow
- B. 500 mL of 23% calcium gluconate as a rapid IV bolus over 1–2 minutes
- C. Oral propylene glycol
- D. 50% dextrose IV
- E. 500 mL of 23% calcium gluconate (borogluconate) IV, given slowly over 10–20 minutes while monitoring the heart
Show answer and explanation, question 9
Answer: E. Slow IV calcium with heart monitoring.
This is parturient paresis (milk fever), stage 2. She can't stand but can stay sternal, and she has the tucked head, cold extremities, low temperature, fast heart rate, and faint heart sounds. Jersey cows are predisposed. Merck's standard adult dose is 500 mL of 23% calcium gluconate IV, given slowly over 10–20 minutes while you listen to the heart.
- A delays effective treatment.
- B: fast calcium can cause fatal arrhythmias. If severe arrhythmias or bradycardia develop, stop the infusion until the rhythm settles.
- C treats ketosis.
- D treats hypoglycemia, not hypocalcemia.

Question 10
Bovine · Professionalism, Practice Management and Wellness
You're treating a lactating Holstein cow for clinical mastitis on a U.S. dairy and are considering extralabel use of an antimicrobial. Which drug is prohibited by federal regulation for extralabel use in this cow?
- A. Enrofloxacin
- B. Oxytetracycline
- C. Procaine penicillin G
- D. Ampicillin
Show answer and explanation, question 10
Answer: A. Enrofloxacin.
21 CFR 530.41 prohibits extralabel use of fluoroquinolones in food-producing animals, and enrofloxacin is a fluoroquinolone. The same list includes chloramphenicol, nitrofurans, glycopeptides, phenylbutazone in female dairy cattle 20 months or older, and others.
B, C, and D aren't on the prohibited list. Extralabel use of them is still allowed only under the conditions of 21 CFR 530.20: a valid veterinarian-client-patient relationship, a substantially extended withdrawal period backed by scientific data, and steps to make sure no illegal residues reach milk or meat.

Question 11
Poultry · Preventive Medicine and Animal Welfare: Veterinary Public Health
A client keeps 20 backyard laying hens. This morning she found 6 dead hens that hadn't looked sick the day before. Several survivors are listless, with swollen, purple combs and wattles, and egg production has dropped. Wild ducks use a pond on the property. What is the most appropriate immediate action?
- A. Necropsy the birds at home and put the carcasses in the trash
- B. Sell the healthy-looking hens before more die
- C. Put antibiotics in the water and reassess in a week
- D. Report it right away to the State veterinarian or USDA at 1-866-536-7593 and follow animal-health officials’ instructions
- E. Move the survivors to a neighbor's coop
Show answer and explanation, question 11
Answer: D.
Sudden deaths without earlier illness, purple and swollen combs and wattles, and a drop in egg production are USDA warning signs for avian influenza. Wild waterfowl contact adds to the concern. USDA tells flock owners to report sick or dying birds right away to the State veterinarian or call 1-866-536-7593. While waiting for instructions, keep poultry separated from wild birds and avoid actions that could spread disease to another flock.
- A handles a possible reportable disease without animal health officials, risking spread and losing the samples they'd need.
- B and E spread a possible highly pathogenic avian influenza outbreak to other flocks.
- C delays the report and doesn't treat a viral disease.

Question 12
Non-species specific · Preventive Medicine and Animal Welfare: Epidemiology
A screening test has 90% sensitivity and 95% specificity. You use it in a herd where 2% of animals have the disease. A randomly chosen animal tests positive. What is the probability it actually has the disease?
- A. About 90%
- B. About 95%
- C. About 27%
- D. About 2%
- E. About 50%
Show answer and explanation, question 12
Answer: C. About 27%.
Picture 1,000 animals:
| Row label | Count |
|---|---|
| Animals with the disease (2%) | 20 |
| True positives (90% of 20) | 18 |
| Animals without the disease | 980 |
| False positives (5% of 980) | 49 |
| All positives | 67 |
| Positive predictive value | 18 ÷ 67 = 26.9% |
When a disease is rare, false positives outnumber true positives even with a good test. That's why predictive value changes with prevalence, while sensitivity and specificity don't.
- A is the sensitivity.
- B is the specificity.
- D is the prevalence.
- E has no basis in these numbers.

What your score on these 12 means
It's feedback on 12 unofficial questions, not a NAVLE score or a prediction. Use it like an error log: each miss names one topic to repair this week. For an official benchmark, ICVA's Self-Assessment is the tool built from retired NAVLE items (see below).
The 2026–27 NAVLE format
Starting with the October–November 2026 window, ICVA split the exam into shorter blocks. The content and total question count didn't change.
| Row label | Before October 2026 | From October–November 2026 |
|---|---|---|
| Questions | 360 | 360 |
| Blocks | 6 | 12 |
| Questions per block | 60 | 30 |
| Minutes per block | 65 | 33 |
| Exam-day length | 7 hours 30 minutes | 7 hours 36 minutes |
Sources: ICVA structure update, May 26, 2026; Candidate Handbook, p. 29.
What that adds up to on the day: 396 minutes of testing (12 × 33), a 10-minute tutorial, and up to 50 minutes of total break time, for 7 hours 36 minutes at the center.
A few rules worth knowing before your first timed block:
- Breaks happen only between blocks. Time left over from a block or the tutorial goes into your break bank. Going over your break time comes out of your testing time. Leaving mid-block is an unauthorized break: the clock keeps running and the proctor files a report.
- The tutorial starts your attempt, even if you skip through it.
- Questions are single best answer. Some options may be partly correct; you pick the most accurate. Scoring is all-or-none, with no partial credit (ICVA Candidate FAQ).
- About 15–20% of questions have images such as photos or radiographs, with zoom, contrast, and pan tools.
- An on-screen calculator is provided. You can't bring your own.
- The exam is offered only at Prometric test centers, not online, in English and French.
Official ICVA practice tools and when to use them
| Tool | What you get | Cost | When to use it |
|---|---|---|---|
| Computer-based tutorial | 20 sample questions on the exam software, English or French | Free | Week 1, so the interface isn't new on test day |
| Sample questions | 5 questions with an answer key | Free | Week 1, to see the vignette style |
| NAVLE Self-Assessment | 200 questions from retired NAVLE items in 4 blocks of 50; projected NAVLE score range and blueprint breakdown | $50 regular; $65 expanded feedback (shows correct answers for questions you missed) | Once mid-plan to direct your studying, and once a few days before the exam |
Details that trip people up:
- Each Self-Assessment must be finished within 30 days of purchase, with no extensions. ICVA recommends ordering at least 7 days before you want to start.
- Take it standard-paced (55 minutes per 50-question section) in one sitting if you want the projection to mean anything. ICVA says that's the mode shown to be predictive, and that it's most useful close to your exam date. The self-paced mode doubles the time.
- A good projection is a strong signal, not a guarantee.
- The Self-Assessment uses 50-question sections, not the new 30-question blocks, so keep doing timed 30-question blocks for pacing practice.

The fee is nonrefundable and can't be moved to another window (Handbook, p. 17). ICVA also lists a $55 NAVLE approval fee; whether it applies depends on your application/approval route, so confirm your route before paying (ICVA FAQ).
- Attempts: Starting with the March 2026 window, every candidate has five attempts. Attempts before December 1, 2025 don't count toward that limit (ICVA, November 17, 2025). Cancelling before you start the tutorial doesn't use an attempt.
- Planning a retake: You can have only one open application at a time. In this cycle, October–November scores arrive inside the March application period. July–August scores come out in September, after the October–November application period has usually closed (it ran June 1–July 15 in 2026). So a back-to-back July-then-October attempt isn't realistic.
Passing score
NAVLE scores are scaled from 200 to 800, and 425 is the minimum passing score. ICVA sets the standard by expert judgment of the content (criterion-referenced) and equates scores across forms, so you're not graded on a curve against other candidates. Results arrive about 4–5 weeks after the window closes, through the NBME portal. Your report shows pass or fail, your scaled score, and a breakdown by content area. There's no exam review, rescore, or appeal (ICVA, Receive Your Results; NAVLE 101).

Protect your license: no recalls, no AI
The NAVLE Candidate Agreement bars studying from confidential NAVLE content. That includes "recalls," reconstructed questions, and lists of topics someone says were on the exam. It also bars discussing questions online after you test, putting exam content into an AI tool, and using any AI platform during the exam. If someone sends you material that claims to contain NAVLE content, you're required to report it to ICVA. Penalties can include score cancellation, a ban from testing, and a report to licensing boards (Handbook, Appendix D, pp. 44–48). Practice from original questions and the official ICVA tools instead.
NAVLE prep FAQs
How long should I study for the NAVLE?
ICVA doesn't publish a recommended length. Our plan uses 12 weeks of steady work around rotations, with 6-week, 4-week, and 14-day versions. The better guide is your own data: your error log and an ICVA Self-Assessment taken standard-paced.
Can I take the NAVLE before I graduate?
Yes, if you're enrolled at an AVMA Council on Education-accredited school. You can test up to twice before graduating. In Canada and most U.S. states, your expected graduation date must fall within 10 months of the last day of the testing window (Handbook, p. 15).
I graduated from a school that isn't AVMA-accredited. What's my route?
Through the ECFVG or PAVE programs. ECFVG candidates must pass the BCSE, and PAVE candidates the QSE, before ICVA will approve a NAVLE application. Board requirements vary, so check with yours (Handbook, p. 15). Candidates seeking a Canadian license apply through the National Examining Board. ICVA's October 12, 2026 notice explains limits for people ordinarily resident in Iran because of U.S. sanctions.
Does passing the NAVLE give me a license?
No. It's required for licensure in every U.S. and Canadian jurisdiction, but your state, territorial, or provincial board sets the other requirements and issues the license. Scores go to other boards through the AAVSB's VAULT transfer service (ICVA, Receive Your Results; ICVA licensing board directory).
