VBC is a comprehensive curriculum for teaching learners who present with missing or weak social, language, and/or cognitive competencies who are at risk for delayed or arrested development. It is the result of over 30 years of research and applied work with children who present with autism and related disorders. 


The David Gregory School in Paramus, NJ, and CIEL, in Barcelona, Spain, provide laboratory settings in which the VBC is being continuously validated and improved.

Methods and Features

The Scope and Sequence Method

A scope and sequence chart lays out the range of the material covered within a course of study in the order in which it will be presented and taught. The detailed scope and sequence chart and accompanying lessons allows teachers to examine the design of the curriculum and determine what is and what is not included in what is being taught.  The VBC scope-and-sequence allows parents and service providers to know exactly what skills and capacities will be taught.
