IES Arrow-Dot Performance in Two Montessori Preschools

Abstract
Preschool children attending two Montessori schools (26 boys, 23 girls at School A; 33 boys, 33 girls at School B) were administered the IES Arrow-Dot Test along with several other psychological tests in order to establish preliminary preschool norms and to test the hypothesis that I-scores would decline, while E- and S-scores would rise over ages 3 to 6. The data supported the hypothesis; however, there were clear differences between the two schools which indicated that much more than age and IQ were determining the level and pattern of the scores.
