Which of the following refers to the strategy that tiers interventions based on the student's response?

The strategy that tiers interventions based on the student's response is known as Response to Intervention (RTI). This approach is designed to identify students who may need additional support and to provide increasing levels of intervention based on their responses to the instruction and support they receive.

In RTI, students are assessed regularly to determine their progress, and intervention strategies are adjusted according to their needs. This tiered approach enables educators to provide all students with high-quality instruction while also offering targeted support to those who are struggling. It fosters early identification of learning difficulties and allows for proactive intervention, minimizing the chances that students will fall behind academically.

This contrasts with the discrepancy model, which typically looks at the difference between a child's expected performance and their actual performance, often awaiting a significant gap before providing support. Universal design for learning focuses on creating an inclusive curriculum that meets diverse learners' needs from the outset, rather than tiering interventions based on response. Direct instruction refers to a structured teaching approach emphasizing explicit teaching, but it does not inherently include a tiered response framework.
