The purpose of this study was to teach three school-teachers to perform part of a contingency analysis: the analysis and interpretation of data about a student's behavior. Fourteen movies were exhibited, which showed a teacher implementing a method of contingency analysis to a student's behaviors. These behaviors were maintained either by the teacher's attention or by escape from academic tasks. Participants observed and recorded the occurrence or non occurrence of the student's target behavior, the antecedent event and the consequence, at 30 second intervals. Afterwards, they answered questions on data analysis and interpretation. The procedure was composed by: Pre-test, Training Procedures and Post-test. On Pre-test, participants made mistakes in the majority of the records and answers to the questions. On Post-test, almost all the records and the answers were correct, which suggests the effectiveness of the training to teach them to analyze and interpret data in a relatively short time.
