The preschool years are critical to the growth and success of young children. The earliest signs of challenging behavior may begin to show during preschool, and a teacher’s response to challenging behavior can either abate or worsen it. The Preschool Life Skills (PLS) program uses a proactive approach to help prevent challenging behavior in the preschool classroom and beyond. The goal of the PLS program is to create a nurturing classroom environment in which all teachers and children promote and reinforce key social skills. The skills taught in the program are based on decades of research in early childhood education and the functional analysis of problem behavior. These include several component skills involved in instruction following, functional communication, tolerance for delays, and friendships. Whether implemented on a class-wide, small-group, or one-to-one level, the PLS program embeds behavioral skills training into normal school routines (e.g., lunch, free play, circle time) to promote efficient acquisition in a naturalistic context. Over a dozen studies have been published on the PLS program, and collectively, they show that social skills greatly increase and problem behavior decreases as a function of program implementation. In this webinar, you will receive a detailed overview of the PLS program, access to free resources (e.g., data sheets, manual) to guide your implementation of the program, ideas for customization, and avenues for future research.
