This study aimed to examine evidences for the validity of the Bender Gradual Scoring System – Bender-Sistema de Pontuação Gradual (B-SPG). Participants were 237 children of both sexes, mean age 8,48 (SD=0,50), from second- and third-grade in public and private schools. The nine Bender figures, projected by a transparency projector, were applied collectively in a single session. The criterion validity was demonstrated for each grade, third-grade students showed a performance clearly superior to second-grade students. The results suggest the need of further studies to investigate other evidences of validity.   Keywords: psychometrics; visual-motor; psychological assessment; Bender Test.
