Attention‐deficit/hyperactivity disorder (ADHD) is one of the most common neurodevelopmental disorders diagnosed among children and adolescents. ADHD is associated with a wide range of health and developmental risks, emotional and behavioral disorders, lack of social skills, and academic underachievement. The purpose of this study was to evaluate the effectiveness of the preschool life skills (PLS) program in teaching important life skills to a 5‐year old girl being assessed for ADHD. The participant was taught eight PLS, divided into three units that focused on instruction following, functional communication, and tolerance skills. Teaching included instructions, modeling, role‐play, and feedback/descriptive praise. The PLS program effectively increased PLS, and skill achievement was only evident when teaching targeted each unit of skills.
