Level systems are commonly used within the Autism Partnership Method. When using a level system, an individual moves up levels for engaging in the desired behavior and down levels for engaging in undesired behavior. This study evaluated the use of a level system using in-the-moment assessment to determine movement to improve mutually enjoyable play between two children diagnosed with autism spectrum disorder (ASD). The results showed the level system was effective in that both pairs of children engaged in more mutually enjoyable play when the level system was in use.
