Academic Achievement over Time By School Time and Income Level (IMAGE)
Caption
Academic achievement over time for children in Montessori (blue lines) versus those in business-as-usual non-Montessori schools; the dotted lines represent children whose family income is lower (average $32, 627) or higher (average $105,804). Within income levels and across school types, performance was equal when children were three years old (Time 1 and TIme 2). Over time, the Montessori children began to perform better. The lower income children in Montessori showed a solid upwards slope and were statistically not different from the higher income children by Time 4 (5 years old). Unfortunately, lower income children in business-as-usual schools showed a strong downwards slope from Time 2 on.
