THIS LISTING is for an economical package of 25 VB-MAPP PROTOCOL booklets (one per student) for the VB-MAPP curriculum for children with autism spectrum disorders and developmental delay. The VB-MAPP is a criterion-referenced assessment tool, curriculum guide, and skill tracking system that is also based on established developmental milestones, and research from the field of behavior analysis. It provides a clear and accurate picture of an individual child's abilities, as well as potential language and learning barriers that may be hindering progress. The VB-MAPP offers a new generation of the application of B.F. Skinner's analysis of verbal behavior to language assessment for children with autism or other developmental disabilities. The VB-MAPP Individual Child Protocol contains scoring forms and charts for each of the 17 milestones, the 24 language and learning barriers, the transition to less restrictive settings assessment, and the over 9 tasks contained in the task analysis of each skill area. (The VB-MAPP program consists of the GUIDE volume plus one PROTOCOL per student.)
