Turning a Strong Program Into a Transformational System

Strengthening Core5 Impact With LETRS Professional Learning

Educators at many districts rely on Lexia® Core5® Reading to deliver structured, adaptive literacy instruction at scale. Core5 provides clear progression, actionable data, and consistent student practice across classrooms. But consistent usage does not always translate into consistent instructional impact.

Without a shared foundation in the science of reading, educators may interpret student data differently. Instructional responses can vary by classroom, even when usage metrics appear strong. Throughout time, this variability affects fidelity and slows systemwide acceleration.

Lexia® LETRS® Professional Learning strengthens the expertise behind Core5 implementation. Educators develop a deeper understanding of how reading develops, how to diagnose underlying skill gaps, and how to align teacher-led instruction with student data. As a result, Core5 becomes more than a practice tool—it becomes a diagnostic and planning engine fully integrated with Tier 1 instruction and Multi-Tiered System of Supports (MTSS) structures.

When Core5 and LETRS work together:

• Data informs precise instructional decisions

• Small-group instruction aligns with identified skill gaps

• Implementation becomes more consistent across schools

• Existing investments deliver stronger returns

The result is instructional coherence at scale. District leaders move beyond monitoring usage to building a sustainable literacy system in which professional learning reinforces instructional tools—and instructional tools reinforce classroom practice.
