The National Professional Development Center on Autism Spectrum Disorders
On this site you will find online modules for identified evidence-based practices. For each of the evidence-based practices there is an evidence-based practice (EBP) brief. These EBP briefs include an overview of the practice, step-by-step directions for implementation, an implementation checklist, the evidence base for the practice, and supplemental materials. EBP briefs and their components are available for download through the EBP Briefs page or directly using the following links: 


Educational Intervention

There is no standard medical treatment for autism spectrum disorder (ASD). No treatment can cure ASD, but intervention can lead to significant improvements in the symptoms an individual experiences. The most commonly accepted treatment is educational intervention. 

Many experts believe that children with autism are less likely than other children to learn from the everyday environment. The principles of Applied Behaviour Analysis (ABA) provide an effective basis for developing strategies to change behaviour and teach new skills. ABA-based techniques utilize teaching tools that focus on simplified instructional steps and consistent reinforcement. These techniques are seldom used on their own. The most successful intervention programs combine different techniques and theories to deal with the great diversity found among children with ASD.

TEACCH (Training and Education of Autistic and Related Communication Handicapped Children) is one of the most widely used educational intervention programmes for children with ASD. TEACCH focuses on maximising the skills of children with autism spectrum disorder by focusing on their relative strengths, rather than trying to “fix” their symptoms. This is different from imposing or dictating a model of "normal" behaviour for everyone and requiring people with autism to fit into the mold whether that is comfortable for them or not. The TEACCH approach respects what they call the "culture of autism"; the relative strengths of individuals with autism in visual skills, recognising details, and memory, among others, as the basis of successful adult functioning. TEACCH has also observed that capitalising on children's interests, even though they may be peculiar from our perspective, helps increase their motivation and understanding of what they are doing. The physical environment is organized, and visual schedules are utilised to make expectations clear and explicit. This environment provides individuals with autism the opportunity to learn independent of adult prompting.

The Ziggurat Group
Learn more about autism, The Ziggurat Model, and services provided by the Ziggurat Group on this website. The Ziggurat Model is a system for designing comprehensive interventions for individuals with autism spectrum disorders. The status quo of intervention is to treat the visible behaviours.  This narrow, Band-Aid approach fails to address the true need—underlying hidden deficits—and provide for sustained change.  No single solution is sufficient to resolve complex needs. The Ziggurat Model is a research-centred system that capitalises on strengths in order to address underlying deficits. It is assessment driven and provides a framework that guides parents and professionals to ensure that complex needs are fully addressed.
