In the response to intervention model, what percentage of students typically receives tier 1 support?

In the response to intervention (RTI) model, tier 1 support is designed to provide high-quality instruction and universal interventions that are effective for all students in the general education classroom. Typically, it is estimated that around 80% of students will respond positively to these tier 1 supports. This approach is based on the understanding that most students will meet educational benchmarks with well-structured, evidence-based teaching strategies that are implemented at the tier 1 level.

The goal of tier 1 support is to prevent academic difficulties from escalating by ensuring all students have access to effective instruction. Monitoring student progress ensures that those who do not respond adequately to tier 1 support can be identified and provided with tier 2 or tier 3 interventions, which are more intensive. Therefore, stating that 80% of students typically receive tier 1 support aligns with the RTI model's foundation of comprehensive instruction aimed at all students in the classroom setting.
