"Autism at-a-Glance" is a series of practitioner and family-friendly documents created by the Center on Secondary Education for Students with Autism Spectrum Disorder (ASD) designed for high school staff members supporting students on the autism spectrum, as well as family members of adolescents with ASD. The purpose of the "Autism at-a-Glance" series is to provide a current summary of topics relevant to high school students with ASD as well as practical tips and resources for school and community personnel and family members. This "Autism at-a-Glance" was designed to support high school staff and family members in understanding and recognizing symptoms of anxiety, and how those symptoms may present in adolescents on the autism spectrum.
