Students with Attention Deficit Hyperactivity Disorders (ADHD) can present unique behavioral and academic challenges within the school environment. The Response to Intervention (RTI) and Positive Behavior Interventions and Supports (PBIS) movements have sought to formalize intervention systems to address the needs of all children. An integral component is the need for initial and ongoing assessment strategies to guide decision making. The assessment strategies reviewed were selected to provide a menu of available resources to assist in matching assessment methods to levels of student needs within the RTI and PBIS framework.
