As a mandate of No Child Left Behind, school administrators are responsible for increasing student academics and state assessment scores. Therefore, administrators must identify problematic areas within the school and creatively implement a resolution plan. Statistics from the Tennessee Department of Education's (TDOE) District Report Card show that students with disabilities enrolled at XYZ Elementary School were not performing on the same level as their peers: on district and state level. XYZ Elementary School appears to have a high percentage of students with Attention Deficit Hyperactivity Disorder (ADHD): diagnosed and undiagnosed. The purpose of this study was to investigate educator's knowledge of ADHD symptoms, understand teacher perceptions of students with ADHD, and to investigate which interventions are used that allows students with ADHD to succeed academically. The goal of the researcher was to ultimately create awareness and a process to implement effective strategies so that administrators and teachers can modify the educational experience for students with ADHD. The qualitative study was conducted using a single-embedded case study approach. Thirty-three Highly Qualified teacher participants employed at XYZ Elementary School participated in the study. The results of the study revealed that majority of the teachers at XYZ Elementary School have limited knowledge of ADHD symptoms and limited understanding of what interventions should be implemented for students to be successful. Recommendation for further research should focus on all schools in the district. In addition, future research should focus on the perceptions of students and parents. A researcher should also conduct a mix methods study to identify which teaching strategy works best with elementary, middle, and high school students that are diagnosed with ADHD.
