This document represents a summary of the report, "Five States' Efforts to Improve Adolescent Literacy." "Five States' Efforts to Improve Adolescent Literacy" describes efforts by five states (Alabama, Florida, Kentucky, New Jersey, and Rhode Island) to improve adolescent literacy. Highlighting common challenges and lessons, the report examines how each state has engaged key stakeholders, set rigorous goals and standards, aligned resources to support adolescent literacy goals, built educator capacity, and used data to measure progress. Responding to questions from state education agency staff members and policymakers, the report describes what each state has done to promote effective adolescent literacy practices in schools and districts. The researchers collected information from policy documents and through interviews with key staff members at state education agencies. Following individual state case studies, a cross-state analysis examines how each state applied five types of strategies for improving adolescent literacy: (1) Engaging key stakeholders to make adolescent literacy a priority; (2) Setting rigorous state literacy goals and standards, with other state policies aligned to support them; (3) Aligning resources to support adolescent literacy goals; (4) Building educator capacity to support adolescent literacy programs at state, school, and classroom levels; and (5) Measuring progress and using data to make decisions and provide oversight. The five strategies were applied with considerable variation across the five states.
