Definition of Reading Intervention. Reading intervention is a program, supplementary to an existing literacy curriculum, that is provided to students for the primary purpose of increasing reading levels. Such programs can be administered both in and out of the traditional classroom environment.
This program focuses on putting proven methods of early reading instruction in classrooms. Through Reading First, states and districts receive support to apply scientifically based reading researchâand the proven instructional and assessment tools consistent with this researchâto ensure that all children learn to read well by the end of third grade. The program provides formula grants to states that submit an approved application.
