Scientific and technological initiation programs are developed to introduce students to scientific research and technological development. We use the term undergraduate research (UR) to refer to both initiation modalities. Our study aimed to evaluate undergraduate students' research experience, self-perceptions, and scientific production during one academic period. Quantitative analysis of curricula vitae and an electronic survey were conducted on students enrolled in a Brazilian Midwest Institute. The results showed that students who had participated in research activities more than once perceived the benefits of UR more positively (p = 0.047) and demonstrated a higher volume of academic production than those were participating for the first time (p < 0.001). Undergraduate students who participate in UR programs contribute positively to academic production and training by providing personal and professional benefits and the opportunity to produce academic work that can help initiate academic careers.
