Purpose: Speech sound disorders (SSDs) comprise a large percentage of school-based speechlanguage pathologists' (SLPs) caseloads, particularly for those practicing in elementary schools. Many service delivery models have been proposed to manage rising caseload sizes. One particular approach, response to intervention (RTI), was introduced as an optional model of intervention in the 2004 reauthorization of the Individuals With Disabilities Education Act and in the 2015 Every Student Succeeds Act. This model ensures that children who may not yet require special education services still receive individualized support. Given the risk for literacy, cognitive, and social impairments in children with SSDs, it is imperative to explore how RTI is implemented for this population of children. Method: In this study, we asked 575 school-based SLPs if they implement RTI for children with SSDs. Furthermore, we explored which practice characteristics and geographical factors may be associated with the use of RTI for children with SSDs. Results: SLPs with smaller caseloads are more likely to implement RTI for children with SSDs. Conclusions: RTI is an optional approach that should be considered for children with SSDs to ensure appropriate and timely service provision. However, the characteristics of an SLP's work setting, such as caseload size, may impede the use of this approach. As such, administrators should work to improve the workload for SLPs, and state legislators should work to support RTI as an option for SLP services. Speech sound disorders (SSDs) are characterized by a delay in acquisition of appropriate speech sounds (
