New York University, partnering with a Head Start program in New York City, will establish co-constructed research goals with Head Start educational staff to enhance on-going whole-child assessment with an emphasis on building capacity for quality assessment of children's social-emotional strengths and needs. Specifically, the study has three objectives: (a) investigate the quality of information from existing child assessments; (b) work toward maximizing the use of information that is already collected to help inform the program's planning around whole-child assessment; and (c) consider how to involve parents in the program around the issue of children's social-emotional development. Participants will include Head Start children (N=187). The psychometric properties of instruments that are employed in the program to measure children's progress in educational classroom settings will be examined and discussed with educational staff. Focus groups will be conducted with parents (N=16) and teachers (N=16) to investigate their perspectives on children's social-emotional development and their role in the process. Researchers anticipate that the results will help parents and teachers improve social-emotional development in Head Start children, and will help determine future steps toward a larger, co-constructed research agenda.
