The What Works Clearinghouse (WWC) develops an agenda for the education topic areas it will review each year. WWC Evidence Report topic areas are chosen to meet the needs of K?12 and adult educators and education decision makers to identify and implement effective and replicable approaches to improving student outcomes. Topic areas for WWC Evidence Reports are defined in terms of the types of interventions, outcomes, and populations of interest in making a causal statement about whether or not interventions work. An intervention within a topic area is a documented program, practice, product, or policy that is intended to have a beneficial impact on important outcomes, such as student achievement, and that can be replicated in different settings.
