Literacy and Numeracy Underachievement

August 2015

A study by the Telethon Kids Institute has found children with Attention Deficit Hyperactivity Disorder (ADHD) have significantly worse school outcomes than children without the disorder.  The Study ‘Literacy and Numeracy Underachievement in Boys and Girls with ADHD’, published in the Journal of Attention Disorders, compared de-identified population data from 6,819 children with ADHD with 14,451 children without ADHD.

Lead author and paediatrician Professor Desiree Silva said the research found both boys and girls with ADHD were significantly less likely to reach the minimum benchmark scores for numeracy, reading, spelling and writing.

Comorbidities are common in children diagnosed with ADHD (Yoshimasu et al., 2012).
