Book excerpt: This curriculum uses the proven principles of applied behavior analysis (ABA) as a way to monitor the progress of children on the autism spectrum and make sure they reach their full potential. It gives adults a clear outline on what to teach and how to teach it, in order to ensure children are reaching developmental goals at this crucial stage. The book's three sections, Assessment, Curriculum and Mastered, each include built-in data collection, which is reproduced on the accompanying online downloadable content so it can be printed off. All three sections cover ten pivotal areas of progress for this age group, including reading, writing, math, conversation and social skills. The Assessment section records the child's initial level of learning and then tracks their progress over time. The Curriculum section provides the lesson plans for the skills which need to be developed, and the Mastered section is a tool for checking that learnt skills are being retained over time. It is also possible to record whether the child has adapted to using the skills in a variety of settings. This curriculum provides everything that an adult working with a child with an autism spectrum disorder would need to ensure a thorough and appropriate ABA program for the young learner.
