Evaluation for Identification and Programming

The occurrence of autism spectrum disorders (ASD) continues to rise. The Centers for Disease Control and Prevention (CDC) report the average prevalence rate for ASD to be 1 in 59 children for 8‐year‐olds from multiple communities in the United States. The data indicates that ASD is four times more common among boys than girls: 1 in 37 boys, compared to 1 in 151 girls (CDC, 2018). This is a 15% increase based on previous estimates reported in 2016 when 1 in 68 children were identified with ASD (CDC, 2016). Research has shown that early treatment leads to better outcomes (Bradshaw, Steiner, Gengoux, & Koegel, 2015). Therefore, early identification can make a critical difference in the lives of individuals with autism. Conversely, delay in identification and intervention is a matter of great concern (Siklos & Kerns, 2007).
