The goal of students admitted to a given course of study is to arrive within the prescribed time at the end of the cycle. Under these conditions, any abandonment is considered as a loss, even if the pupil who interrupts his studies before being at the end of the cycle has acquired knowledge that has raised his level of education. In the same way repetition, although allowing the recovery is considered as loss because it reduces the capacity of reception of the classes and thus prevents other children to be admitted there or to cause overpopulation of student. The burden of drop-out and repetition appears in the input / output ratio as a measure of school performance. The objective of this research is to determine the degree of effectiveness of the training system at the Maranata Institute in 2012-2016, then to realize that the reconstituted cohort proves that students who have started a cycle are certified at the end. of it. That is, to analyze the non-monetary performance of the training system within this institution. While the efficiency of the educational system is our concern, let us say that this is the ability of this system to achieve the objectives it prefixes. This one apprehends both internally and externally.
