The Veterinary Technician National Examination (VTNE) is owned and administered by the AAVSB. The VTNE is used to evaluate entry-level veterinary technicians’ competency to practice and to be credentialed. The computer-based exam is given in three testing windows a year and is constantly updated, reviewed and reevaluated by highly-qualified item writers so that it remains a valid tool. Most states and provinces require a passing score on the VTNE as one criterion for credentialing. The AAVSB contracts with the administering agencies to provide the exam. PSI is the exam vendor for examination development and administration services regarding the VTNE. The exam is administered at PSI Testing Centers throughout the U.S. and Canada.
