Graduating competent veterinarians with the appropriate knowledge and skills to support and strengthen their country's National Veterinary Services is a key priority for veterinary institutions globally. The World Organisation for Animal Health (WOAH) developed a set of Day 1 Competencies that should be expected of every veterinary graduate. Veterinary schools need to be able to assess the coverage of these competencies in their curriculum and determine the level of proficiency of their graduates. This article describes the iterative design and development process used to create a semi-quantitative, competency-based assessment survey. The Evaluation Tool for WOAH Day 1 Graduating Veterinarian Competencies is used as part of a stepwise process to systematically assess a veterinary curriculum regarding these competencies. This tool was developed and tested at the University of Gondar College of Veterinary Medicine and Animal Sciences in Ethiopia. The Evaluation Tool was successful in systematically collecting, measuring, and analyzing the perceptions of faculty, senior veterinary students, recent graduates, and external stakeholders about the level of proficiency of graduates in all 19 WOAH Day 1 Competencies. It was specifically designed to be used in conjunction with curriculum mapping to provide a full picture of how effectively these competencies were taught and identify gaps that needed to be addressed. This tool, the supporting resources, and the methodology are now globally accessible to all veterinary institutions, enabling them to revise and update their curricula and, ultimately, improve the training of the future veterinary workforce to support veterinary services in their respective countries.
