Study finds common ADHD classroom accommodations fail to improve student success

New study challenges standard school supports

A new investigation from Florida International University suggests widely used classroom accommodations may be ineffective for students with attention-deficit/hyperactivity disorder. Four specific strategies were assessed by the team, such as taking frequent breaks, standing while at a desk, utilizing low-distraction environments, and extending time on assignments. Gregory Fabiano, who serves as a psychology professor at FIU and led the study, reported that not one of these approaches produced significant gains in student behavior or grades. The research involved 255 children in kindergarten through sixth grade who participated in the university's Summer Treatment Program between 2022 and 2025.

Behavioral interventions show clear benefits

While standard accommodations showed no significant effect, behavioral interventions and stimulant medication produced measurable positive results for the participants. Behavioral supports reduced rule violations during independent work by 37 percent compared to when children received neither treatment. Stimulant medication lowered those same violations by 61 percent while also helping students complete more assignments and earn higher quiz scores. Fabiano noted that reducing symptoms does not necessarily address the underlying challenges interfering with a child ability to learn.

One size fits all approach fails

Fabiano explained that these approaches fail to build skills or address motivation which are critical for academic success. The findings challenge the assumption that identical accommodations will work for every student with attention-deficit/hyperactivity disorder regardless of individual needs. Teachers can incorporate positive behavioral supports such as praising appropriate behavior and setting clear expectations into everyday classroom routines. Some children may still benefit from specific supports depending on their unique requirements rather than a universal solution.
