This document includes the Early Screening Inventory: Revised (ESI-R), a developmental screening instrument for 3- to 6-year-olds, and an examiner's manual. The inventory comprises two sample scoring sheets, one for preschool (ages 3-4) and one for kindergarten (ages 4-6), and a parent questionnaire. The inventory is intended to be individually administered for the purpose of identifying children who may need special educational services. Key features of the ESI-R are: ease of learning and administration, time requirement of 15-20 minutes per child, and ease with which administrators can interpret and parents understand results. The measure covers the developmental areas of visual motor/adaptive, language and cognition, and gross motor skills. The inventory has been standardized and validated with 6,000 children, many of whom were enrolled in Head Start programs. It was found to be highly reliable and highly valid. The examiner's manual includes chapters on general screening guidelines; directions for administering and scoring the ESI-P (Preschool); directions for administering and scoring the ESI-K (Kindergarten); differences in administering and scoring the ESI-P and the ESI-K; interpretation of ESI-R results; and standardization, reliability, and validity data for the ESI-R. Additional training materials (not part of this package) include a trainer's manual and two videotapes. (Contains 14 references.) (DB)
