The Preschool COR is an observational assessment tool for children aged 21/2 to 6 years. It is designed to measure childrenÂ's progress in all early childhood programs (including but not limited to those using the High/Scope educational approach). It looks at 32 dimensions of learning in six broad categories critical for school success: Initiative, Social Relations, Creative Representation, Movement and Music, Language and Literacy, and Mathematics and Science. Teaching staff gather information to complete the COR in the course of everyday program activities, so COR assessment is seamlessly integrated with early childhood teaching and planning. The results provide detailed information on each childÂ's development, as well as a variety of group reports analyzing progress for various audiences. The Preschool COR Kit provides the materials needed for assessment, curriculum planning, and reporting to parents for a group of 25 children. The second edition of the Preschool COR has been revised and expanded to better meet the needs of early childhood educators for meaningful assessment directly tied to teaching and curriculum planning. While the basic process of using the Preschool COR has not changed (those already using COR assessment will make a smooth and easy transition to this new version), materials have been added to make it easier to collect information on each child, to inform parents about the COR process, and to plan teaching strategies around COR results. Developmental indicators have been revised to provide closer alignment with the Head Start Child Outcomes Framework and the High/Scope key experiences.
