This session discusses the new reading screener requirements and highlights how universal screening serves as a cornerstone of Tier 1 instruction and data-based decision making within the California Multi-Tiered System of Support (CA MTSS) framework. Participants will explore how early screening supports equitable access to literacy learning, informs differentiated instruction, and ensures that actionable next steps are in place once results are collected. Through a concise blend of research, state guidance, and practical application, the session will demonstrate how screening data connects directly to instructional action, moving from identification to support. Attendees will leave with examples from a practitioner perspective and resources they can integrate into teacher preparation coursework and TK–12 partnerships, reinforcing the CA MTSS commitment that “All Means All."
