Autism Spectrum Disorder (ASD) and Adolescents

What is autism and how can we best support students on the autism spectrum and their families? Learn more about how adolescents feel about being on the autism spectrum, how to help them succeed, and books and resources to support your growing awareness.  

Autism spectrum disorder (ASD) is a complex, neurodevelopmental disorder that affects people’s behaviors and interactions with others and the world around them. ASD is a spectrum disorder, therefore its affects can range from mild to moderate to severe, impacting individuals very differently. There is no known single cause of autism but early diagnosis and intervention can have significant, positive impacts on individuals and their families.  

ASD and literacy development

Many students with ASD demonstrate word reading strengths but experience difficulties in reading comprehension, especially when asked to think beyond the text and infer meaning from what they are reading. For adolescent readers, being able to understand characters’ varying perspectives and social interactions within a story is usually vital to understanding the whole story within middle grade and young adult literature but students with ASD often struggle to make sense of these aspects of the text. As you can imagine, similar difficulties in writing often occur with students on the autism spectrum. 

Co-occurence of ASD with dyslexia and ADHD

Are autism, dyslexia, and ADHD related disorders? As students on the autism spectrum are being identified more readily, questions have emerged about ASD’s comorbidity or co-occurrence with dyslexia and ADHD. 


There are a limited number of studies looking at students on the autism spectrum and dyslexia and within those students there a lot of variance in the prevalence rate of dyslexia in children on the autism spectrum (6% to 30%). Unlike ASD, research in dyslexia has been complicated by historically varying opinions on how to define dyslexia. Broader definitions that include long-term struggling readers and Gough and Tunmer’s (1986) “garden variety” poor readers and/or “poor comprehenders” within the dyslexic umbrella likely result in more children, including those with ASD, identified as on the dyslexic spectrum (Russell and Pavelka, 2017). Conversely, the co-occurrence of ASD and dyslexia is much lower within research where the definition of dyslexia has been limited to a language-based disorder defined as an unexpected, extreme difficulty in learning to read with a core phonological processing issue. 


ADHD is thought to occur in approximately 5% of the general population but its prevalence is considerably higher in children diagnosed with a reading disability (between 25% to 40%). This is not completely surprising given that ADHD and dyslexia often share several symptoms such as information-processing speed, naming speed, and working memory challenges. ADHD also has a high comorbidity rate with ASD (between 30% to 50% of children diagnosed with autism also show symptoms of ADHD. 

Listen as autism expert, Dr. Ebony Holliday, discusses the importance of diagnostic clarification with autism and co-occurring conditions. Watch more clips from our recent interview with Dr. Holliday to learn more about her exciting research and work with students on the autism spectrum and their families. 

Ebony Holliday, PhD, from the Kennedy Krieger Institute’s Center for Autism Services, Science and Innovation (CASSI), discusses how co-occurring conditions like ADHD and anxiety disorder can muddy the waters for getting a proper autism diagnosis and what families can do to ensure diagnostic clarification.

Inference and Informational Text

Inferencing is something we do all the time, but often students don’t realize this is a skill they naturally use. Watch as a 6th grade ELA teacher uses a simple photograph to help her students recognize all the information they can infer from the photo.

What Does It Take to Teach Inferencing?

Reading comprehension instruction should focus on guiding students to think actively about the ideas in text. I suggest treating inferencing not as a skill but as a strategy for intentionally making sense of text.
