I support schools to support their students with autism. This is a great process for implementing intervention plans that not only help identify the priority behaviour, the possible function, but more importantly consider the underlying characteristics, which is often not considered in schools. I will be sharing this information with schools when asked to support with intervention.

As a MSY Youth and Family Coach, using the ZIG/UCC's is part of what we do in order to develop planning that makes sense for the youth. This course just helped me understand a little bit better how to apply what I have been attempting to do.

Coordinator of Social-Emotional-Behavioral Supports & Family Engagement

Jennifer Baldwin, MEd

Strongly agree: My knowledge about developing an effective program for individuals on the spectrum has improved by taking this Ziggurat FBA course. I would recommend the Ziggurat FBA course to others.

Watch How The Ziggurat Model
Helps Teachers, Providers, and Parents

The Ziggurat Model has been adopted by schools and agencies.
It helps you to work smarter not harder!

If you're a teacher or service provider, you don't want your students to lose any time—
but you may also wonder if you have the skills to help a student
challenged by autism.

If you're the parent of an autistic child, you want your child to live
the most fulfilling life possible—but you might feel helpless at times.

The Ziggurat Model's Founders

Meet the licensed psychologists who have created the Ziggurat Model.

Ruth Aspy, Ph.D.

Dr. Aspy specializes in transdisciplinary assessment and intervention for individuals on the spectrum. She understands that treating behaviors will not result in real change. Instead, underlying needs must be addressed.

Barry G. Grossman, Ph.D.

Dr. Grossman specializes in counseling and assessment for people who are on the spectrum, as well as their families. He teaches that intervention cannot be successful unless it’s comprehensive and all steps are covered.

Addressing Behavior Challenges:
Creating a Specific Ziggurat FBA

Extension course on the Ziggurat Model

Autism can be stressful. Autistic children and students may find themselves overwhelmed by the challenges they face every day.  Feeling misunderstood, rejected, or in a constant state of crisis, it is not uncommon for them to display meltdowns/shutdowns and even to develop anxiety and depression.  Caring parents and teachers want to help. They want to make a difference but feel frustrated because their efforts do not seem to pay off - like they are working in the dark and may not know how to help. Time is always a factor.  Parents are worried about not only today but the future. They may worry: 

  • Will my child ever have friends?
  • How can I get my child through the morning without a meltdown?
  • Will my child be punished for his autism?
  • How will she ever hold a job?
  • Will my child ever be happy?
  • What is going to happen to him after we are gone?

Teachers and other educational professionals don’t want their student to have a “lost” school year.  They may worry: “Do I have the skills to help this student?” “Will this student keep others from learning?”  or “How will I survive this school year?”  

Both parents and educators want to help instill skills for success. They need answers - "How will we overcome all the obstacles?"  What they need is the Ziggurat Model. 

Learn about the award winning Ziggurat Model that has helped families and educators for over 15 years!   

The Ziggurat Model is a system for designing comprehensive strategies and supports for all individuals on the autism spectrum. The Ziggurat Model was created to simplify a complex process. The focal point of the model is a five tiered research-centered system that capitalizes on strengths to address underlying needs. It is assessment driven and provides a framework that guides parents, professionals, and autistics themselves in creating effective supports and strategies.

The Ziggurat Model is used in home, school, mental health, and other therapeutic settings. The Ziggurat Model is also used by autistic adolescents and adults as a self-help strategy. 

Recent trends in special education emphasize the use of scientifically based research approaches along with a focus on multi-tiered system of supports (MTSS). Additionally, there is a strong push for incorporating positive behavioral interventions and supports (PBIS) based on a functional behavioral assessment. The Ziggurat Model facilitates these practices.

The Ziggurat Model is unique - simple to use and comprehensive. While it is easy to find volumes of information describing specific interventions, it is difficult to find information on how to develop an effective plan. Autistics, parents, and professionals will find the framework of the Ziggurat Model to be a useful guide in developing more thorough and effective supports and strategies.

The Ziggurat Model will help you to develop supports that work.  There are four steps to the framework:

  • Assess underlying needs and strengths for planning
  • Identify meaningful priorities for change
  • Develop a plan that works: The five essential levels of support
  • Implement the plan

Read what people are saying about the Ziggurat Model!


“I found this book to be extremely thorough and comprehensive. There are many applications for a text like this. I personally would like to buy about 10 copies and hand them out to all of my child’s special and general education teachers, but I also believe that other team members (psychologists, therapists, and parents) can benefit from this comprehensive resource. The book does an excellent job of painting a picture that will help many “see” autism and understand that a comprehensive plan can make a huge difference. I’ve had the privilege of working with the authors and know that their comprehensive view and strategies have helped my child.”

Parent and author

Kristi Sakai

“Comprehensive and well-researched, but also understandable and accessible, the ZM addresses the multi-faceted needs of children with ASD in the school setting. Its very premise is that while there are commonalities, the characteristics of autism impact every student differently. This program is ingenious in that it creates an individualized plan and a framework in which to implement it. It is a well-oiled mechanism that smooths the wrinkles out of the school day for every child. In addition, as a parent it’s exciting for me to think of the multitude of ways we can further use the information we gain about our kids through, for example, using the UCC (Underlying Characteristics Checklist). The ZM is not merely a support system, but a celebration of what is unique about our kids on the spectrum and a springboard for their future.”

Autism Education Specialist

Kari Dunn Buron

The Ziggurat Model, developed by Ruth Aspy and Barry Grossman, is a model for intervention that addresses the underlying issues of autism as they impact a student's ability to learn and thrive in our school environments. This highly efficient program clearly illustrates for educational teams how to develop solid and effective IEPs that "keep the autism in mind." The approach is practical, research based, and easy to implement. I highly recommend the use of the Ziggurat Model when developing either individual plans or creating district-wide autism programming standards.

Fred R. Volkmar, M.D.

“A practical and helpful book that provides a comprehensive approach to intervention for more able individuals with autism. The book is enhanced by use of cases and diagrams and has a practical orientation. It will be of great benefit to professionals and parents alike.”

Occupational Therapist, Author of The Interoception Curriculum

Dr. Kelly Mahler, OTD, OTR/L

The Ziggurat Model provides a respectful framework for helping you identify how you can better support autistic children and adults. Many times we do not account for or skip over very important aspects of the autistic experience thus failing to provide supports that are an actual match for what the person truly needs to thrive. I love the Ziggurat Model's tiered approach that helps us consider underlying needs in a sequential manner. If you are seeking to grow in your ability to provide meaningful supports, learn about the Zig! ——Dr. Kelly Mahler OTD, OTR/L, author of The Interoception Curriculum: A Step-by-Step Framework for Developing Mindful Self-Regulation

Executive Director of the EPIC School, Founding Chairman of the Scientific Council for the Organization for Autism Research

Peter F. Gerhardt, Ed.D.

“With the Ziggurat Model of intervention, Drs. Aspy and Grossman have synthesized the research on program planning and functional behavior assessment into a useful and user-friendly decision model leading to the development of truly comprehensive, functionally determined educational and behavior support plans. Highly recommended.”

Author, Presenter, Autism Advocate

Brenda Smith Myles, Ph.D.

“In the past ten years, I have seen three materials that I believe have the potential to advance the progress of children and youth with ASD. One is the Ziggurat Model. Aspy and Grossman understand ASD in a way that most people do not. They have created a simple-to-use, yet comprehensive model to ensure that children’s needs are met throughout the school day. The Ziggurat program is innovative, based on best practices and focused on the child’s needs. I wish that I would have created this model. It is simply brilliant.”

Program Director of the Autism Center at OCALI

Amy E. Bixler Coffin, M.S.

“I love this book! In this much-anticipated publication, Aspy and Grossman have done an exceptional job at providing a user-friendly process and framework for designing comprehensive interventions for individuals with autism spectrum disorder. It is a must-have reference for all educators, clinicians, and parents who work and live with children with ASD.”

The Ziggurat Model is perfect for special educators

IEPs are better with the Ziggurat Model!

The Ziggurat Model helps staff to complete multiple components of the IEP. The framework helps school staff to remain in compliance with federal and state guidelines. Specifically, recent trends in special education law emphasize the use of scientifically based research approaches along with a focus on response to intervention (RTI). Additionally, there is a strong push for incorporating positive behavioral interventions and supports (PBIS) and multi-tiered system of supports (MTTS). The Ziggurat Model is consistent with these practices.

  • Complete BETTER functional behavior assessments (FBAs)

  • Develop a behavior intervention plan (BIP) that addresses critical needs

  • Facilitates a person-centered approach to program development

  • Facilitates effective collaboration with parents and staff

  • Develop accommodations that address key needs

  • Develop transition plans that address needs associated with autism and build on skills

  • Identify present levels of academic and functional performance (PLAAFP) in areas such as social, communication, and emotion regulation
