1.1 AVECCTN Examination Structure, Blueprint & Credentialing

AVECCTN Examination Structure, Blueprint & Credentialing

The Veterinary Technician Specialist in Emergency and Critical Care [VTS (ECC)] credential represents the highest level of recognized clinical expertise in veterinary emergency and critical care nursing. It is conferred by the Academy of Veterinary Emergency and Critical Care Technicians and Nurses (AVECCTN), which received provisional recognition from the National Association of Veterinary Technicians in America (NAVTA) Committee on Veterinary Technician Specialties (CVTS) on January 15, 1996, and administered its first certifying examination to 26 candidates at IVECCS VI in September 1998.

Achieving the credential requires a multi-year process: qualifying clinical practice, a two-part peer-reviewed application portfolio, documented advanced procedural competency, and a 200-question certifying examination. Everything in this section is drawn from AVECCTN's published Constitution and Bylaws, its Examination Information page, and its current application instructions — where the Academy does not publish a value, this guide says so rather than inventing one.

AVECCTN Credentialing Eligibility Criteria

The Bylaws (Article VII) and the current Part A instructions set the following prerequisites:

1. Professional Credentialing: The applicant must be currently credentialed to practice as a Veterinary Technician or Veterinary Nurse (or equivalent), with no lapses in that credential during the qualifying work period. A gap in licensure resets the work-experience timeline. If credentialing is available in the applicant's state or country it must be held, even where it is not legally required; AVECCTN does accept applicants from countries where no credentialing pathway exists.
2. Clinical Practice Hours: Three years of full-time work experience — not less than 6,000 hours — in veterinary emergency and critical care medicine. All hours must fall within the five-year period ending the day before the application year begins (November 1), must be earned while credentialed, and are capped at a maximum of 40 claimed hours per week across all employers. Applicants report an average percentage of weekly hours spent in ECC (roughly 10–20% for general practice with occasional emergencies, up to 100% for a dedicated emergency service or ICU); the Academy does not publish a minimum percentage, but the Credentials Committee may request verification.
3. Continuing Education: A minimum of 25 hours of CE related to emergency and critical care, completed within the same five-year window (all CE must be finished before November 1). Acceptable sources are broad: a nationally recognized conference; a local, state, regional, or national veterinary/technician/nurse association; an accredited veterinary or technician school CE program; the American Association of Veterinary State Boards (AAVSB); RACE-approved CE; or publicly advertised local meetings delivered by recognized subject-matter experts. Proof of attendance is required, and the instructor's credentials must be those they held at the time of the lecture.

Application trap: AVECCTN uses the VECCS definitions of emergency care and critical care to judge whether both your hours and your CE actually qualify. If a CE title does not make the subject obvious, submit the official course synopsis alongside the attendance certificate — the synopsis is not itself proof of attendance.

Application Portfolio Architecture: Part A & Part B

The application is split into two submissions across a single November 1 – October 31 collection year.

Part A: Pre-Application (Preliminary Screening)

Submitted online between November 1 and March 31 (due March 31 at 11:59 PM EDT) with a non-refundable application fee of $75. Part A evaluates four things only: work history/hours, license history (every licensed year, no breaks), continuing education, and two letters of reference. Decisions are issued by April 30; declined applicants may appeal. Only accepted applicants may submit Part B.

Reference letters must come from a Veterinary Technician Specialist in emergency and critical care, anesthesia, or internal medicine; a VECCS veterinarian; or a Diplomate of the American College of Veterinary Emergency and Critical Care (ACVECC). Until sufficient numbers of those referees exist, the Academy also accepts letters from board-certified specialists in anesthesia, internal medicine, and surgery. Letters must be submitted through the online reference form — emailed letters are not accepted.

Part B: Skills List, Case Logs & Case Reports

Due October 31. Cases are collected and skills are signed off across the entire November 1 – October 31 year.

• Case Log (50 cases minimum): Each entry records date, patient identification, species/breed, age, sex, weight, diagnosis, length of care, final outcome, and a summary of the nursing techniques and procedures the applicant personally performed. The log must reflect management of emergent and critically ill patients and mastery of advanced nursing skills. Note that AVECCTN explicitly states you do not need to write out drug doses in the log — "calculated and administered a fentanyl CRI" is the level of detail wanted, because the log exists to show skills and involvement, not pharmacy math. Use generic drug names only; brand names (Cerenia, Lasix, Keppra, Unasyn, and similar) are a common reason applications get flagged.
• Four Case Reports (≤5 pages each, double-spaced): Selected from the case log, original work of the applicant, demonstrating expertise in the nursing management of a variety of emergency and critical care patients. References follow the AMA format used by the Journal of Veterinary Emergency and Critical Care (JVECC).
• AVECCTN Skills List: The Advanced Veterinary Emergency Critical Care Nursing Skills Form documents mastered advanced nursing skills and is revised as practice standards change. For the 2027 cycle the list comprises 26 core skills (all required) and 16 advanced skills, of which 8 must be completed. Most photo-documented skills must now be shown performed on a live patient, with per-skill photographic instructions published separately; the single exception is the required photograph of the practice's defibrillator. Neither patient nor applicant may be identifiable in the images. Attestant qualifications are published in a dedicated instructions document.
• RECOVER CPR Certification: All applicants must complete the online RECOVER BLS and ALS certification and submit a current certificate. A certification that has lapsed beyond two years is not current and must be renewed through the online recertification process.

Certification Term & Recertification

VTS (ECC) status is not a lifetime award. Under the Bylaws, certification is conferred for a period of five years, beginning on the first day of the month in which the examination is passed, and recertification is required every five years. Recertification is granted on successful completion of 60 CE units/points, evaluated by the Recertification Committee and granted by the Directors. Candidates must also pass the examination within three years of their original application acceptance date; after that a completely new application and credential package is required.

AVECCTN Examination Architecture & Domain Weights

The certifying examination is held once annually in September, in conjunction with the International Veterinary Emergency and Critical Care Symposium (IVECCS), and takes place the day before IVECCS begins. It is now delivered entirely online under remote proctoring; candidates receive the technical requirements after their application is approved.

Do not memorize a clock. Prep sites frequently quote a specific sitting length for this exam. AVECCTN publishes the item count but not a time limit and not a numeric passing score, and the fee is re-set every year. Treat any specific minute count or cut score you see elsewhere as unverified.

The Official 13-Domain Blueprint

The Academy publishes an approximate blueprint derived from the VTS (ECC) job analysis and role delineation survey. The weights below are the official published percentages and total exactly 100%.

Three domains tie for the heaviest weight at 12% each — Cardiovascular, Gastrointestinal, and Fluid/Electrolyte/Acid-base. Together with Respiratory (11%), those four disciplines account for 47% of the examination, which is where the bulk of study time belongs. Note also that Toxicology/Pharmacology is its own 5% domain, and that Musculoskeletal and Reproductive are two separate 3% domains, not a combined category.

The Cross-Cutting Question Dimensions

Within every discipline, AVECCTN states that questions may be asked about:

• Anatomy and pathophysiology
• Etiology and risk factors
• Triage
• Signs and symptoms
• Diagnostic procedures
• Monitoring
• Implications of failure on other systems
• Goals of therapy
• Patient management
• Complications

The Bylaws add that ancillary diagnostic techniques appear in each topic, and that because a VTS (ECC) must understand how procedures are performed, the examination covers indications, equipment needed, complications, and troubleshooting for common clinical procedures. The Academy is explicit that it tests not only recall but the ability to comprehend, apply, and problem-solve — which is why this guide pairs each disease process with the monitoring, equipment, and failure modes that surround it.

AVECCTN's Own Recommended Reading List

The Academy states it "cannot define conclusively the body of knowledge necessary to pass the AVECCTN examination" and offers its reading list, last updated in 2021, only as a guideline.

Strongly recommended textbooks:

• Silverstein & Hopper — Small Animal Critical Care Medicine (listed as the 2015 edition; a 3rd edition was published in 2022)
• Battaglia & Steele — Small Animal Emergency and Critical Care for Veterinary Technicians, 4th ed. (2020)
• Burkitt Creedon & Davis — Advanced Monitoring and Procedures for Small Animal Emergency and Critical Care (listed as the 2012 edition; a 2nd edition was published in 2023)
• Drobatz, Hopper, et al. — Textbook of Small Animal Emergency Medicine (2018)
• Plunkett — Emergency Procedures for the Small Animal Veterinarian (2013)
• Norkus — Veterinary Technician's Manual for Small Animal Emergency and Critical Care, 2nd ed. (2018)
• DiBartola — Fluid, Electrolyte, and Acid-Base Disorders in Small Animal Practice (2012)

Journals and other sources: the Journal of Veterinary Emergency and Critical Care (VECCS) and the Multiple Disciplinary Tech Review at IVECCS.

Supplemental reading: Thomovsky, Johnson, et al., Basic Monitoring in Canine and Feline Emergency Patients (2020); Randels-Thorp & Liss, Acid-Base and Electrolyte Handbook for Veterinary Technicians (2016); Willis, Fluids and Electrolytes Made Incredibly Easy! (2019); Day, ECG Interpretation in the Critically Ill Dog and Cat (2005).

Because the list is dated 2021, pair it with the current RECOVER CPR guidelines — first published in 2012 and updated in 2024 — which you must certify in anyway, and with recent JVECC consensus statements. Finally, build fluency in emergency drug math: unit conversion (mg/kg/min ↔ mcg/kg/hr, mEq/L, mOsm/L), fluid and drip-rate adjustment, and multi-drug CRI compounding.
