Introduction: Learning laparoscopic surgery skills using a simulator board is one of the new acquired teaching methods. This work seeks an evaluation method to assess, by objective means, the development of psychometric skills during a simulated workshop with biological pieces. Material and methods: During a 2-month period, 15 students from an endoscopic surgery seminar were evaluated using a simulator board with the objective to assess four specific skills: object mobilization, cutting pattern, sutures and intracorporeal knots. Eight practice procedures with biological pieces were performed in the simulator. Time and precision were measured in the four assignments. Results: Students improved significantly in object mobilization (p = 0.02), precision in cutting pattern (p ‹0.01) and suture (p = 0.02), and time and precision to realize intracorporeal knots (p ‹0.01). Conclusions: This method allows the objective evaluation of the degree of development of surgical skills using a simulator board. It is inexpensive and easy to perform, which makes it useful for other institutions. Key words: simulator board, medical education, endoscopic surgery, psychometric skills.
