The document discusses assessment-driven instruction for reading programs in grades K-3. It defines assessment-driven instruction as using data from valid reading assessments that measure six components of reading. Teachers use several types of assessments, including screening, progress monitoring, diagnostic, and outcome assessments. The data from these assessments helps teachers identify students' reading levels, group students for effective instruction, target skills to reteach, and monitor student progress. The Lead Literacy Teacher's role includes scheduling assessments three times per year and implementing interventions for students at risk.
