The aim of the study was to obtain normative data for a representative sample of Venezuelan children for the Child Behavior Checklist (CBCL) and Teacher’s Report Form. The sample was constituted by 1141 children, boys and girls aged 5 to 12 (MeaN= 8.79; SD=1.85), 49% female and 51% male. Socioeconomic status was significant in a way that low SES parents scored their children as having more problems. Gender has an effect on the scores; males were perceived with more behavior problems than girls for both parents and teachers. Parents and teachers did not show agreement in the assessment of the children’s behavior. Findings of this study suggest that the syndromes and dimensions assessed by the two versions of the checklist have universal validity for school-age children.
