In this 20-page report (released in July 2002) from the Working Paper Series at the Harris School of Public Policy at the University of Chicago, Professor C. Cybele Raver offers an extended discussion of the importance of young children's emotional development in preparing for school. Throughout the report, Professor Raver reviews a great deal of existing research in order to examine whether the emotional adjustment of children can be affected by early interventions programs, such as Head Start. After this extended literature review, Professor Raver suggests that the emotional and behavioral problems of young children can be quite costly to their success rate in school, and that these problems can in fact be reduced over time. Persons working as public policy advocates on behalf of children will find a great deal of interest in this well-written report.
