About 1500 children from an inner city school district and a suburban school district were asked to perform eight tasks of basic skills. There were differences in the performances of the children. The differences depended upon the socio-economic background of the children. On many of the skills, third grade urban children were similar to first grade suburban children. It is for this reason that the inner city children in this study were considered disadvantaged and a program of skill development has begun. Inner city children must have experiences that will help them acquire the skills that suburban children have acquired before entering school.
