Reading First is a federal program that mandates a specific kind of data collection and a three-tiered assessment system. This applies to children from kindergarten to grade 3. It focuses on classroom-based assessments which are not necessarily standardized. Reading First classrooms ensure individuals are provided differentiated instructions in small groups. The groups must be differentiated by:
Over four years, the program led to increased numbers of students reading at grade level, fewer children being designated as high-risk readers, and overall improved reading scores.
Importantly, Reading First has not been shown to decrease the achievement gap between low and high SES readers. Both groups did improve, but they did so at the same rate.
