Buysse and Peisner-Feinberg (child development, U. of North Carolina at Chapel Hill) offer a 29-chapter handbook on the application of response to intervention (RTI) in early childhood settings. Education, child development, and other researchers mainly from the US describe its assessment and instructional components, program-level supports, and underlying infrastructure. They detail the origins and features of RTI, the state of knowledge about it in early childhood, and issues related to implementation; its foundations in public health models of prevention and school-age and pre-kindergarten models of RTI and positive behavior support; formative assessment tools, such as the individual growth and development indicators, the CIRCLE-Phonological Awareness Language and Literacy System, and tools to assess behavioral skills and social-emotional development; curriculum for language and literacy, math, and social-emotional development; program-level supports, including family engagement, professional development, the role of public policy, and the need for adaptations for diverse learners; and consensus-building efforts, recommended practices from implementation science, next-generation innovations, and ways to build the evidence base.
