This study aimed to gather evidences of validity for the Bender test - Gradual Scoring System (B-SPG), investigating developmental changes based on the relationships between its scores and the ages of the children. The study investigated 1052 children attending from pre-school to fourth grade of eight municipal and state public schools of Campinas (a city in the state of São Paulo, Brazil) and the surrounding region. Ages ranged from six to ten years old, with an average of 8,35. The findings indicated that according to the increase of age, the B-SPG scores diminished, suggesting that the distortions progressively diminish as the children become older. Although other studies are suggested, the results presented here are consonant with researches that sought to establish that it is possible too find a maturational character among the figures of the test.
