The eleven studies which comprise the Consortium for Longitudinal Studies were described in order to determine long-term effects of preschool education on disadvantaged children. Research methods and results of the studies were evaluated and compared. An historical overview details the sociopolitical milieu from the time the eleven studies began in the 1960s to the present. Theories which impacted the preschool movement in the 1960s were also discussed, particularly those which concern the development of intelligence, the importance of early education and environmental impact on the development of intelligence. Demographic data were used to describe disadvantaged children's needs for quality early intervention programs. The results of the eleven Consortium studies indicate positive long-term effects for disadvantaged children enrolled in quality preschool programs.

In this study, 78 kindergarten and first-grade children were interviewed about their writing to identify indicators of self-assessment. Writing samples for each participant were saved over a three month period, then compared and discussed by the child. Results indicated that these young children did engage in self:-assessment behaviors. The classroom teachers were asked to place the participants in their classes along a writing continuum known as a Writing Band. Graphs were presented to show the writing levels of the children by classroom. In addition, each classroom was surveyed to document events which promote literacy development within the framework of an integrated curriculum. Writing samples for each child were collected and kept in a portfolio. Participants were interviewed regarding the contents of the portfolio. Children in two of the kindergarten classes were interviewed using 5 samples collected over a 2 1/2 month time period, and all other participants were interviewed using 6 writing samples collected over a 3 month period. Findings indicated that not only did these young children recognize growth in their writing, but they also assessed that growth based on outward, physical features of their writing. The writing ability of each child at the beginning of the study did …
