Introduction: Laparoscopic surgery brings multiple advantages to the patient but represents a challenge for the surgeon due to the difficulties it introduces, like diminished range of motion, decreased tactile sensation and two-dimensional vision. The vision of the surgical field is fundamental. Lack of experience in its use may have a negative impact in the outcome of a surgery. For that reason, training in minimally invasive surgery must include exercises to dominate the laparoscopic scope, especially the 30° degree scope. Methods: A comparative, transversal study based on construct validation of a proposed model for training and skill-development in the use of the 30° laparoscopic scope. Results: A total of 20 individuals were evaluated, 10 experts vs 10 rookies, considering as experts those surgeons with more than 250 laparoscopic procedures using the 30° scope , and rookies as those with no experience in laparoscopy. The group of experts did the practice in a shorter time and with fewer errors than the group of rookies (p = 0.0004 and 0.0002 respectively). Conclusions: The proposed model is able to distinguish between different levels of experience, validating it as a useful tool for training.
