Teachers' perceptions regarding the effectiveness of ADHD interventions were investigated. The different forms of interventions that were focused on included: stimulant medication, classroom/parent environmental interventions, a combination of stimulant medication and classroom/parent environmental interventions, and counseling. Elementary and middle school regular education teachers completed surveys revealing their perceptions of student success in a variety of areas while using one of these four interventions for ADHD. The results indicated that teachers perceive a student with ADHD to be most successful while using the combination of stimulant medication and classroom/parent environmental interventions. These findings support other research that has shown that stimulant medication is effective as a short-term intervention, environmental interventions are effective with longer lasting results and that a combination of the two is the most successful long-term.
