Response to intervention (RtI) was instituted following the 2004 reauthorization of the Individuals with Disabilities Education Act (IDEA). The role and delivery of school-based occupational therapy (OT) services were not defined in the reauthorization of IDEA. However, the scope of school-based practitioners has broadened as a result of RtI initiatives. The RtI supplemental resource manual, developed as a project proposal for this capstone, defines the role of OT in RtI and the delivery models that align with county policy and funding. The supplemental resource provides OT recommended evidence-based interventions that can be feasibly implemented by the general education teacher within the classroom to support at-risk students or prevent issues from developing requiring further special education services. School systems often report that handwriting is the number one reason for OT referrals. Therefore handwriting interventions are the focus of this supplemental resource.
