Pearson Education Widens Access to Early Testing and Assessment

Acquires Rebus Inc., Developer of Screening and Assessment Tools for preK-grade 6

Pearson Education, the global education business of Pearson plc (NYSE: PSO), today announced the purchase of Rebus Inc., a leading developer of screening and assessment tools for use with young children. Pearson Early Learning will offer to schools across the U.S. two popular research-based tools designed to detect developmental delays, help improve instruction, and further child development. The Early Screening Inventory (ESI) is a screening tool for children ages 3-6 used to identify young children at risk for school failure. The Work Sampling System (WSS) is a comprehensive performance assessment tool for pre-kindergarten through sixth grade. Both tools are based on rigorous research and development by Rebus Inc. founder, Dr. Samuel J. Meisels.

Dr. Meisels, a leading researcher in the fields of early childhood assessment and early intervention and an advisor to Head Start and Title I programs, said, "Early screening allows us to detect developmental delays as early as age three. We can then provide intervention to help each child succeed." He added, "This collaboration with Pearson Early Learning will help bring the ESI-R and WSS to a much wider audience than we have ever been able to reach before." In January 2002, Dr. Meisels will take over presidency of Chicago’s Erikson Institute, a graduate school for child development studies, and will continue to work with Pearson Education as a consultant.

The Early Screening Inventory is a comprehensive screening instrument that accurately identifies children who may need special educational services in order to perform successfully in school. The Work Sampling System is a performance assessment that helps teachers document and assess children’s skills, knowledge, behavior, and academic accomplishments. Through observing, recording and evaluating everyday classroom-based experiences, activities and products, teachers better understand what students are learning, what students are beginning to master, and what areas still need work. Correlated to current national and state standards, WSS has been used in tens of thousands of classrooms, assessing hundreds of thousands of students, and has been proven to increase student performance on standardized tests.

“Recent federal efforts have focused on the importance of effective early screening and are promoting research-based cognitive development activities for preschool-age children,” noted Kathryn Costello, president of the Pearson Early Learning Group. “These screening and observational assessment tools will help teachers and caregivers to teach each child according to individual strengths and needs – thus helping to close the gap before children even reach kindergarten.”
