Evidence and Gap Map of Tier 2 Literacy Interventions for Grades K–3 in the Commonwealth of the Northern Mariana Islands

Title:	Evidence and Gap Map of Tier 2 Literacy Interventions for Grades K–3 in the Commonwealth of the Northern Mariana Islands
Description:	The Commonwealth of the Northern Mariana Islands Public School System requested a systematic review of Tier 2 literacy interventions for students in grades K–3. This review defines a Tier 2 literacy intervention as a supplemental instructional program for students who require support in addition to the Tier 1 core reading program. Of the 267 studies on Tier 2 literacy interventions identified, 20 met What Works Clearinghouse 5.0 standards with or without reservations. Two interventions—Reading Recovery and Literacy First—had strong evidence of positive effects (as defined by the Every Student Succeeds Act) on students’ literacy skills. One additional intervention—Achieve3000—had moderate evidence of positive effects. This report includes an evidence and gap map and a supplemental matrix that highlights implementation strategies used in each intervention.
