Graduation Statistics

    (Barkley, 2015; as summarized by CHADD, 2023)

  • Students with ADHD are significantly more likely to experience grade retention and academic failure.
    (Barkley, 2015)

  • Academic difficulties in students with ADHD are largely driven by deficits in executive functioning, including organization, planning, and task completion.
    (Langberg et al., 2011)

  • Students with ADHD are more likely to experience school disciplinary actions, which are associated with increased dropout risk.
    (Evans, Owens, & Bunford, 2014)

  • ADHD was associated with lower report card scores and lower standardized exam performance in grades 9–12.
    (Folkins et al., 2024)

Social Statistics

  • Adolescents with ADHD are at increased risk for anxiety, depression, and low self-esteem. (Sibley, 2014)

  • Teens with ADHD are 2–3 times more likely to engage in risky behaviors, including: substance use, unsafe driving, and impulsive decision-making (Molina & Pelham, 2014)

  • Youth with ADHD are more likely to be both victims and perpetrators of bullying. (Unnever & Cornell, 2003)

  • Teens with ADHD have fewer close friendships and more conflict in relationships. (Bagwell, 2001)

  • Social skills were a significant predictor of academic achievement in students with ADHD. (DiPerna, 2005)

  • Youth with ADHD who experienced peer rejection showed significantly lower academic performance and school engagement. (Mrug, 2012)

  • Interventions targeting social and behavioral functioning in ADHD resulted in significant improvements in academic performance. (Evans, 2014)

Intersectionality Statistics

  • Black children were 69% less likely and Hispanic children 50% less likely to be diagnosed with ADHD compared to White children.
    (Morgan, 2013, Pediatrics)

  • Black students are more likely to be disciplined for behaviors associated with ADHD rather than referred for evaluation or support.
    (U.S. Department of Education, Civil Rights Data Collection, 2018)

  • Girls with ADHD are less likely to be referred for evaluation due to less disruptive behavior.
    (Quinn & Madhoo, 2014)

    (Danielson, CDC, 2018)

  • Students of color with disabilities (including ADHD) are significantly more likely to experience exclusionary discipline (suspension/expulsion).
    (U.S. Department of Education, 2018)

  • ADHD is linked to poorer academic and social outcomes, but these outcomes are worsened by systemic inequities such as poverty and lack of access to support. (Russell, 2016)

  • LGBTQ+ youth with ADHD show significantly higher rates of depression, anxiety, and suicidality than both: LGBTQ+ peers without ADHD and ADHD peers who are not LGBTQ+. (Whitney, 2022; Trevor Project data)
