Autism Spectrum Disorder (ASD)

Definition: A child with an Autism Spectrum Disorder (ASD) is a child with a developmental disability significantly affecting verbal and non-verbal social communication and social interaction, generally evidenced by the age of three. Other characteristics often associated with ASD are engagement in repetitive activities and stereotyped movements, resistance to environmental changes or changes in daily routines, and unusual responses to sensory experiences.



This guidance document (Guidelines for the Educational Evaluation of Autism Spectrum Disorder, February 2014) has been developed to assist school district personnel and families in becoming familiar with the wide range of characteristics and abilities of their students with an autism spectrum disorder (ASD) and in applying Colorado's new eligiblility category of Autism Spectrum Disorder (ASD) to identify students eligible for special education services.  Schools have experienced a steady increase in the number of students with ASD over the past 10 years.  In 2012 the Center for Disease Control (CDC) estimated that about 1 in 88 young children have an ASD.  The information in these guidelines may be used to guide the process of identifying students with ASD and developing appropriate programming, supports and services.
