The document discusses how the Classroom Performance System (CPS) can support Response to Intervention (RTI). RTI uses a multi-tiered approach to provide differentiated instruction to students based on their needs. CPS allows teachers to engage all students, provide immediate feedback, and use assessment data to drive instruction and identify students who need additional support. It also supports the three tiers of RTI instruction by enhancing questioning, facilitating discussions, and enabling differentiated instruction based on formative and summative assessments.
