The Impact of Initial Level of Performance on Multidisciplinary Team Eligibility Decisions When Using Response to Intervention

Abstract

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 research suggests that final level of performance is the main factor in MDT decisions. ROI is influenced by pre-intervention performance and is also inherently captured in students’ postintervention level, potentially limiting ROI's utility as a distinct indicator of performance. To address these issues with ROI, this study examined whether initial performance level and ROI improve actual MDT decisions about special education eligibility beyond the final level of performance. Results indicate that initial level of performance and ROI add no additional value to predicting MDT's eligibility decisions when using RTI despite identified students having significantly lower initial performance levels and lower ROIs than their nonidentified peers.
