Miranda is a social worker completing a family assessment. As she acquires more information from the parents on a six-year-old son and his behaviors, it becomes obvious that further assessment will be required. The child’s teacher has contacted the parents with complaints about his conduct at school. He does not appear to be able to focus on specific tasks and becomes bored after a few minutes, failing to complete any assignments. Running around the classroom during quiet time is becoming a daily habit, and the child forgets where he puts things. What kind of assessment will the social worker refer for this child?
