Coherence 101: What Is It, and Why Does It Matter?

Across the country, educators are working urgently to close long-standing learning gaps. Yet progress remains uneven. In roughly half of U.S. public elementary and middle schools, the average student is still not proficient in reading or math. And in TNTP’s 2024 analysis of nearly 28,000 schools, only 5 percent of schools where students performed below grade level were helping those students catch up—and stay caught up.

For too many young people, falling behind in school means staying behind.

Even as schools offer additional support, those supports may not connect to one another—or to the core instruction students receive every day. All young people deserve learning experiences that make sense and prepare them for academic and postsecondary success. But too often, students’ experiences are fragmented and disconnected from grade-level content crucial to accelerating learning. The problem isn’t a lack of commitment, effort, or resources. The problem is a lack of coherence.

Coherence has two essential dimensions: instructional coherence and systems coherence.

Instructional coherence means aligning instruction, content, and goals across all learning spaces—from core instruction to intervention and other academic supports—to ensure all students engage in, and are actively prepared for, grade-level learning.

Additional help builds directly on what students are learning in class rather than steering them toward unrelated tasks that focus on remediation. Students experience a logical progression of concepts, routines, and expectations across settings, making learning more predictable and productive.

Systems coherence ensures that the policies, structures, and practices across a district or state make instructional coherence possible. That includes aligned guidance from states, district investments in high-quality materials, common assessments, and opportunities for teachers, specialists, and tutors to plan together. When systems are not aligned, even well-designed instructional efforts can become fragmented.

The two forms of coherence are interconnected: coherent instruction better engages young people in grade-level learning; aligned systems create the conditions for sustained coherent instruction at scale.

In many schools today, strong systems and instructional coherence remain the exception rather than the norm. A 2024 RAND study found that on average, teachers use five different supplemental programs each week to support differentiation and small-group instruction. For students who also receive intervention, special education, or multilingual services, the number of disconnected materials and approaches they encounter grows even larger. On paper, students who are behind may receive hours of additional support each week, but in practice little of it is designed to help them access grade-level content. Instead, these layers often create confusion for students and overwhelm educators.

The consequences are real. In one 2023 study across four Tennessee districts, students in the bottom 10 percent who were assigned to intensive Tier III intervention actually made less growth than similarly performing students who received no intervention at all. Incoherence doesn’t just slow learning—it can actively undermine it.

There are schools, however, where students who have fallen behind do catch up and sustain that progress over time. In The Opportunity Makers, TNTP studied a group of these trajectory-changing schools. One finding stood out: schools where students made sustained gains shared a focus on instructional coherence.

In these schools, each piece of their instructional program—curriculum, materials, interventions, and assessments—works in concert with the others to advance the same grade-level expectations, and teachers make those connections clear to students and their caregivers. Regardless of their starting point, all students were working toward the same grade-level goals using aligned routines, strategies, and concepts.

Students often previewed key ideas in intervention before encountering them in class. They could recognize connections, anticipate what was coming next, and feel more confident about participating. One superintendent described the shift this way: “It doesn’t feel like they’re behind; it feels like they’re getting the code.”

Coherent learning experiences don’t require students to navigate competing approaches or conflicting messages. Instead, every part of the day reinforces students’ ability to access rigorous, grade-level work.

TNTP works with schools, districts, and states to help turn coherence from an aspiration into everyday practice. Our support includes:

Across all of this work, our goal is simple: to help every student access challenging, grade-level learning through a coherent and connected educational experience.

TNTP’s publication, Coherence by Design, explores what it takes to build coherent instructional systems—and highlights a district that dramatically improved student outcomes by transforming its intervention model. As educators and leaders look for solutions that move beyond fragmented approaches, coherence offers a clear path forward.
