In the RTI model, when should comprehensive evaluations occur?

In the Response to Intervention (RTI) model, comprehensive evaluations are most appropriately conducted during the intensive intervention tier. This tier is designed for students who have not responded to previous interventions and require a more targeted and in-depth assessment of their learning needs. Comprehensive evaluations can help identify specific areas of difficulty, inform instructional strategies, and determine if a student qualifies for special education services. This is crucial for tailoring interventions that can effectively support the student's unique learning profile.

Conducting comprehensive evaluations during intensive interventions ensures that educators have the necessary data and insights to make informed decisions about the student's educational path, including the potential need for specialized support. It situates the evaluations within a framework that emphasizes targeted assistance when standard interventions haven't yielded sufficient progress, thus enabling a better approach to addressing the student's needs.
