To meet the increasing needs and diversity of students many schools are adopting the Response to Intervention (RTI) model. Three main obstacles interfere with the successful implementation of this three-tiered intervention structure: failure to deliver quality whole-class instruction, problems with early identification and monitoring, and lack of diversification in the school setting. Schools need to ensure that all students receive quality, whole-class instruction. Educators must continuously monitor and identify students who require additional support. This is only possible when all staff collaborate to meet the diverse needs of all students. Full commitment is required by all staff to overcome the obstacles that threaten the successful implementation of the RTI structure.
