Fundamental Foundations: Research-Aligned Tier 1 Instruction in Early Elementary

Strong reading instruction starts in Tier 1. When foundational literacy instruction is aligned with reading research, all students benefit. Fewer students start to struggle in third–fifth grades when instructional gaps widen, students with disabilities can be identified earlier to receive intervention, and advanced readers can develop a deeper understanding of language and the strategies needed to access complex texts and writing tasks. 

However, many early elementary classrooms still rely on practices that assume children will intuit patterns of print on their own, leaving too much of reading success up to chance. At the same time, it is understandable that meaningful differentiation often feels time-consuming and unsustainable for teachers in a Tier 1 setting.

According to Nancy Young’s Ladder of Reading and Writing (updated 2023), up to 60% of children require explicit, code-based instruction to become skilled readers, spellers, and writers. These students may not have diagnosed reading disabilities or stand out as needing intervention in the early grades, but without systematic instruction in how written language works, they likely are to fall behind over time. We know this gap exists because the NAEP scores continue to show high percentages of struggling readers in fourth and eighth grades. This places Tier 1 instruction at the center of both prevention and equity.

The good news is evidence-based reading instruction is not just for intervention or tutoring. When implemented thoughtfully, research-aligned practices can strengthen whole-class instruction without adding to teacher workload. In fact, having a clear road map for effective reading instruction often simplifies planning and makes differentiation more manageable.

Alignment Is Key

Effective Tier 1 instruction prioritizes clarity, coherence, and intentional practice. Reading, writing, and spelling are interconnected systems that build cumulatively. When instruction is aligned across these areas, students gain more meaningful practice and teachers gain clearer insight into student learning, which is especially critical in the early grades.

Differentiation and Executive Functioning

Early elementary classrooms include a wide range of learners: students who already are reading, students who are just beginning to decode, multilingual learners, and students who need more repetition and structure. Whole-class differentiation does not require endless materials or multiple lesson plans. Differentiating along an existing Scope and Sequence takes into account how reading develops, where students currently are, and where they need to go. Additionally, explicit attention to developing executive-functioning skills helps students manage increasingly complex tasks and build transferable learning skills. With the right instructional shifts, teachers can meet varied needs efficiently while maintaining high expectations.

Morphology and Etymology: Supporting Language and Decoding

Vocabulary and background knowledge play a critical role in early reading success. Early exposure to word meanings, language structure, and patterns within words supports both reading accuracy and comprehension, particularly when instruction is intentional and developmentally appropriate.

Assessment as a Planning and Communication Tool

Assessment can either support or hinder Tier 1 instruction. While assessing whole classes, especially with young students, can feel overwhelming, efficient assessment in key areas provides meaningful information without over-testing or sacrificing instructional time. When assessment data is directly connected to instruction, it becomes a powerful tool for planning next steps and communicating clearly with families about student progress.

Rachel Sorsel (@mindfulteacherrachel) will present a practical, research-informed webinar focused on supporting all learners from the start. Participants will learn how to:

• Increase alignment between reading, writing, and spelling instruction (and more)
• Differentiate effectively without increasing workload while building executive-functioning skills
• Build vocabulary and background knowledge through early attention to word structure
• Use assessment efficiently to guide instruction and communicate meaningful insights to families

This webinar is designed for early elementary educators and administrators seeking manageable, evidence-based shifts that strengthen Tier 1 literacy instruction and support long-term student success. Watch here.
