 The Ziggurat Model: Planning Comprehensive Behavioral Interventions for Individuals with Autism Spectrum Disorders


The Ziggurat Model is a guide for designing comprehensive behavior interventions for individuals of all ages with autism spectrum disorders. The Model has been adopted at the district-wide and state-wide levels. The Ziggurat approach centers on a five level system, structured in a hierarchy. Each level represents an area that must be addressed in order for an intervention plan to be comprehensive. The premise of the Ziggurat Model is that underlying needs and characteristics related to the autism spectrum must be addressed. Assessment tools to facilitate this process will be introduced.
Parents, teachers, speech pathologists, psychologists, physicians, occupational therapists, counselors, school administrators, autism consultants, and others will benefit from this training. Emphasis is placed on working as an intervention team. Through hands-on exercises, participants will learn to:

  • Recognize strategies with empirical support
  • Select appropriate strategies for an individual
  • Address underlying needs through comprehensive interventions

The Ziggurat Model is unique in its approach and fills a void by providing a framework for organizing the range of possible interventions and assuring that true, meaningful needs are addressed.


The workshop will be held in Jefferson City, Missouri, Governor's Office Building, 200 Madison Street, Room 450 on Thursday, February 21, and Friday, February 22, 2013. Monday, June 10 and Tuesday, June 11.  Registration will begin at 8:30.  The fee for attendance is $145. Parents may attend at the discounted rate of $100. IDAC's may attend at the discounted rate of $75.


Participants will be able to:

  • Discuss theories that attempt to explain the signs and symptoms of autism
  • Use specially designed assessment tools to identify the relationship of underlying characteristics of ASD with observable behavior:
  • A survey of underlying characteristics (UCC)
  • A survey of individual strengths and skills (ISSI)
  • List five areas required for a comprehensive intervention
  • Identify research validated strategies for intervention on each of the five levels of the Ziggurat
  • Identify common pitfalls in intervention design for individuals with ASD
