Veterinary students may pursue extracurricular surgical experiences before performing ovariohysterectomy or orchidectomy in their veterinary curriculum. We sought to evaluate the impact of these experiences on student confidence and subsequent surgical performance during students' first canine ovariohysterectomy or orchidectomy during their veterinary school curriculum. We enrolled 69 third-year veterinary students to complete pre- and post-operative surveys reporting their confidence to perform surgery and self-assessing their performance. Students had all completed five semesters of surgical skills training on models and cadavers but varied in their participation in extracurricular surgical experiences. A subset of students ( = 27) were digitally recorded while performing ovariohysterectomy (16) or orchidectomy (11). Digital recordings were scored by a blinded rater using task-specific rubrics and a global rating scale, and time to perform the procedure was recorded. The number of extracurricular surgeries students had performed was positively correlated with their confidence to perform orchidectomy ( = .78) but not ovariohysterectomy ( = -.17). There was no correlation between extracurricular surgeries performed and subsequent rubric scores or surgical times for the first ovariohysterectomy ( = -.01 and = -.14, respectively) or orchidectomy ( = .09 and = -.18, respectively) performed as part of their veterinary curriculum. Our results suggest that extracurricular surgical experiences may not impart a long-term improvement on performance scores or surgical time during students' first surgery of their veterinary curriculum. Additional research is necessary to clarify how model training and extracurricular surgical experiences on live animals interact to affect students' subsequent surgical performance.
