When using response to intervention (RTI) for special education eligibility decisions, multidisciplinary teams (MDTs) may use performance level and rate of improvement (ROI) as two metrics when evaluating student responsiveness. Although examining student responsiveness to instruction is a critical component of an evaluation using RTI, previous…

Educators use curriculum-based measurement of oral reading (CBM-R) to measure student response to instruction. Current decision-making frameworks assume students demonstrate linear growth across a school year. However, growth appears nonlinear for at least a subgroup of students. We assessed the degree to which grade two (n = 800) and grade three…

No matter how one formally define response to intervention (RTI), most definitions contain common components: scientific, research-based instruction; the use of learning rate and level as the basis for determining effectiveness of intervention; and decisions about intensity and duration of interventions based on a student's response to…
