Identifying and supporting students in early elementary grades with low literacy achievement is critical to help them achieve grade-level proficiency and stay on track academically. "Reading Recovery"® is an intervention that provides one-on-one tutoring to students in grade 1 with low literacy achievement. This supplemental program aims to improve student reading and writing skills by providing one-on-one tutoring, tailoring the content of each lesson to each student based on observations and analyses of the student strengths and weaknesses from prior lessons. This Intervention Brief provides an overview of the full Intervention Report, which summarizes the available evidence on the effects of "Reading Recovery"® on student achievement in elementary school.
