Purpose: This lead article of the Clinical Forum focuses on the research that supports why speech-language pathologists (SLPs) are an integral part of the overarching curriculum for all students in schools. Method: Focus on education has shifted to student performance in our global world, specifically in college and career readiness standards. This article reviews recommendations on best practice from the American Speech-Language-Hearing Association on SLPs' roles in schools, as well as data on school-based services. Implementation of these practices as it is applicable to school initiatives will be explored. Methods of interventions available in schools, from general education to special education, will be discussed based on national guidelines for a Response to Intervention and Multi-Tiered System of Support. Research regarding teacher knowledge of the linguistic principles of reading instruction will be explored, as well as correlation between teacher knowledge and student performance. Results: The implications for how SLPs as the linguistic experts offer unique roles in curriculum and the evidence available to support this role will be explored. Implications for future research needs will be discussed. Conclusion: The demands of a highly rigorous curriculum allow SLPs a unique opportunity to apply their knowledge in linguistic principles to increase student performance and achievement. With the increased focus on student achievement, growth outcome measures, and value-added incentives, it is critical that SLPs become contributors to the curriculum for all students and that data to support this role are gathered through focused research initiatives.
