This study assessed teacher readiness at All Saints Catholic School to implement Response to Intervention (RtI) through surveys before and after professional development sessions. Initially, teachers were unfamiliar with RtI and concerned about support and resources. After training, teacher agreement with positive survey statements about RtI increased significantly. The results show that providing effective professional development before implementing new programs can increase teacher buy-in and confidence in using new strategies. Future work should examine how to include parents and students in RtI.
