The assessment and evaluation of educative initiatives are often characterized by lack of orga nization, which is probably due to the multilevel nature of t he educational phenomenon. We encounter this situation in Pequenos Cientificos (Little Scientists), a Colombian program in active learning for pre-college science and engineering education, on top of other difficulties related to changes in schools, teachers, children, and management systems. In this paper we present a brief overview of the rationale behind the assessment sys tem we chose for this program. We focus on a management system that allows monitoring and feedback to diffe rent actors and levels involved in this initiative. This process and an analysis of its results are presented in ter ms of coverage, consolidation and quality. Pequenos Cientificos introduces another way to do Engineering in Education, going beyond the analysis of generalities or global visions, and taking into account little scientists and their environment (interpersonal-educational-psychological).
