Before we start behavioral therapy, an assessment is completed. ABS currently offers two different assessments. The first assessment is The Assessment of Basic Language and Learning Skills-Revised (The ABLLS-R), developed by Partington (2006). It is utilized to assess the current language skills of the child, and determine all skill deficits across each verbal domain. The second Assessment is The Verbal Behavior Milestones Assessment and Placement Program: The VB-MAPP is a criterion-referenced assessment tool, curriculum guide, and skill tracking system that is designed for children with autism, and other individuals who demonstrate language delays. The VB-MAPP is based on B.F. Skinner’s (1957) analysis of verbal behavior, established developmental milestones, and research from the field of behavior analysis. (www.marksundberg.com/vb-mapp.htm).
