The document describes the Behavior Evaluation Scale - Fourth Edition: Short Version (BES-4:S), which measures behavioral and emotional problems in children ages 4-18. It has five subscales: Learning Problems, Interpersonal Difficulties, Inappropriate Behavior, Unhappiness/Depression, and Physical Symptoms/Fears. Normative data were gathered from thousands of students and the instrument demonstrates high levels of reliability and validity. Each item is rated on a 7-point scale regarding frequency of behaviors. The assessment takes about 20 minutes to complete and provides standardized scores that can be used to compare students and identify needs.
