The manual details an observational code designed to track a child during an entire day in a preschool setting. The Eco-Behavioral System for Complex Assessments of Preschool Environments (ESCAPE) encompasses assessment of the following three major categories of variables with their respective subcategories: (1) ecological variables (designated activity, activity initiator, materials, location, grouping, composition); (2) teacher variables (teacher definition, teacher behaviors, teacher focus); and (3) student variables (target behaviors, competing behaviors, verbal behaviors). Sample completed ESCAPE data sheets are included along with a glossary listing the definitions for each of the codes. The code is an attempt to quantify the array of variables that interact to affect program outcomes on a day-to-day and even a moment-by-moment basis. (CL)
