PURPOSE: To characterize and compare the fine motor, sensory and perceptive functions of students with Attention Deficit Disorder with Hyperactivity (ADHD) and students with good academic performance, without behavior alteration. METHODS: Participants were 22 male students from Elementary School distributed into: GI - 11 children with ADHD; and GII - 11 students with good academic performance and no behavior alteration. Students were submitted to the Protocol for Evaluation of Fine Motor, Sensory and Perceptual Function, and to the Dysgraphia Scale. RESULTS: There were differences between GI and GII in tasks concerning fine motor function, sensory function, and perceptual function, with lower performance from GI. All students in GI presented dysgraphia. CONCLUSION: Students with Attention Deficit Disorder with Hyperactivity present lower performance regarding fine motor, sensory and perception functions in relation to students with good academic performance. These difficulties can cause significant impact on academic performance, impairing the development of written language and causing dysgraphia in these students.
