Solving education’s coherence problem: Insights for school and district leaders

Instructional coherence in education has a lot in common with the concept of harmony. Even without formal musical training, we all perceive harmony. Similarly, we also perceive its opposite, dissonance— when musical notes seem to clash.

Composers sometimes include short bursts of dissonance to build tension and cause us to crave resolution, but no entire work of dissonance will ever pack in the crowds. It just isn’t enjoyable.

Instructional coherence is K–12 education’s version of harmony, when the parts work together to create a unified whole. Sadly, education systems frequently struggle to achieve coherence and, like musical compositions with too much dissonance, are less effective than they could be.

What causes this lack of coherence and, more importantly, how can school and district leaders best address this challenge?

What is instructional coherence in education?

Consider this example from TNTP (2024) of an instructional program that lacks coherence. An elementary school principal purchases a digital reading intervention program with the goal of raising state test scores, especially for her Latinx and multilingual learners. She then revises her school schedule to include time for the new intervention.

What is the result? To quote TNTP:

All students have a core reading block and an intervention reading block every day, in addition to the English Language Development block for multilingual learners. But for students, these feel like completely disconnected periods: in core instruction, students might read and discuss a grade-level text about the Civil War; in intervention time, students read a below-grade-level text about the planets in our solar system; in tutoring, students read a fictional piece about the Holocaust.

After this expensive purchase and all the effort to ensure that students have access to a reading intervention program, the principal is surprised to find that her students’ reading performance is not improving any faster than it was before.

In contrast, consider this example from CCSSO (2026) of an instructional program with a high degree of coherence. A grade 4 ELA class is working on a unit about human anatomy:

Today, students are learning about the circulatory system and reading a story about how blood flows through the body. Ana, an emerging reader, is excited to dive into the high-quality text but needs help decoding and understanding multisyllabic words such as “circulation” and “hemoglobin.”

In tutoring before class that morning, Ana reads an easier text on red blood cells, building her content knowledge about the heart and blood vessels. When Ana gets to her general education class, in a small group led by a co-teacher, Ana reviews other words that start with “circ,” such as “circle” and “circumference.”

All of these exercises work together to help Ana access the lesson on the grade-level content. The teacher, co-teacher, and tutor coordinate her learning using her core classroom materials as the anchor.

As a result, Ana has a seamless learning experience, even though she interacts with different adults in different settings.

These examples show us—in TNTP’s words—that instructional coherence involves “ensuring that every element of an instructional program and its strategies—from core instruction to interventions to extended time—works together to advance the same set of grade-level student experiences.”

This sounds logical and may even appear easy at first glance, but it’s much harder to achieve than one might think. Why is this the case?

Challenges to achieving instructional coherence in schools

When it comes to instructional coherence, districts tend to start out well. They typically purchase a textbook series with a documented alignment to their state standards. At this point, coherence is high. It’s everything that occurs beyond this first step that begins to create dissonance.

This is because even the most complex collections of resources provided by textbooks do not represent the totality of the instructional experiences that educators must provide. In seeking to supplement the textbook, school and district leaders encounter three distinct challenges.

Challenge 1: Providing aligned skills practice

Many textbooks contain insufficient resources for students to adequately practice the skills being taught. As a result, schools purchase supplemental practice programs. Depending upon the design of such programs, dynamics may be introduced where students are practicing skills that are not associated with the current grade-level unit. This represents one level of incoherence.

Challenge 2: Providing tiered supports

Additionally, some students have more specialized needs. TNTP notes, for example, that many curricula “do not include enough high-quality materials and guidance to support multiple tiers of instruction, English Language Development, and multilingual learners.” Again, educators find themselves needing additional resources, but if the content being presented through these resources is not expressly tied to the current grade-level unit, further incoherence creeps in.

Challenge 3: Targeting student skill gaps

On yet another front, MTSS and other statutory requirements (e.g. screening for the characteristics of dyslexia) require the use of interim assessments. While validity requirements generally ensure that assessments are aligned to state standards, the data that flows from assessments can easily introduce “noise” into the system. This happens when assessments have no ability to filter the information they present through the context of the current grade-level unit.

Consider a grade 3 teacher working through a unit on geometry, with the goal of having students find the area of a rectangle by using the formula “length x width.” Instructional planning recommendations from an assessment with no ability to filter content in consideration of current grade-level topics might present unclear next steps for a student struggling with this skill (e.g., a student performing at the grade 2 level).

How so? The recommendations would include not only the missing prerequisites but also other skills from grade 2, not directly related to area. These additional skills represent “noise” that the teacher cannot use in implementing Accelerated Learning approaches.

An assessment, however, that can present data directly related to the standards and skills of the grade-level unit would be highly coherent and would unquestionably support Accelerated Learning.

Rethinking textbook alignment to promote instructional coherence

When discussing coherence, we must acknowledge that the role of textbooks is paramount in many schools. Teachers may go days, weeks, or even months without consulting state standards documents, but they use their textbooks and associated resources virtually every day.

Documents from the state department of education typically don’t drive instructional programs nearly as much as textbook units and associated pacing guides do.

For this reason, it’s essential for supplemental resources to be aligned not only to state standards but also to the specific textbook being used. A teacher instructing on Unit 1 of Math Textbook A needs something different from a teacher addressing Unit 1 of Math Textbook B.

To put this another way: The growing emphasis on instructional coherence demands a fundamentally new definition of alignment.

Historically, alignment has often been reduced to a mapping exercise, with the results presented in spreadsheets. The conversation has typically sounded like this: “Consult this spreadsheet where we, the vendor, show you how the skills in our assessment—listed in Column A—align with your state standards, listed in Column B. For example, our skill 24 aligns with your standard 3.b.2c…”

This approach, however, has two major failings:

#1: Lack of true textbook alignment

First, it ignores the central driver of daily instruction: the textbook. Teachers do not teach from spreadsheets. They teach from the units, lessons, and sequences in their core curriculum. Yet traditional alignment frameworks make no room for this reality. They assume that if the skills generally “match” the standards, then the instructional system is coherent.

In truth, coherence can only emerge when supplemental tools are able to recognize and connect to the specific curriculum in use. It’s not enough to say two things relate to the same standard. Instead, students must encounter content in an order that reflects what they’re actually learning in class.

Guidance from CCSSO makes this explicit, noting that aligned tools must be “intentionally designed to match the core curriculum, building from the same learning standards with the same scope and sequence.” Simple skill‑to‑standard checklists cannot meet this bar.

#2: Failure to focus on instructional sequence

Second, traditional alignment focuses on similarity, not sequence. Just because a program contains the same skills does not mean that it presents content to students—or presents data to teachers—in a way that corresponds to the current unit, lesson, or instructional moment. Programs rarely know what is being taught, when it’s being taught, or how the textbook structures the learning progression.

Truly useful alignment must account for how instruction actually unfolds in classrooms, not how it fits on a spreadsheet. This is why we need a new definition of alignment itself. Rather than mere alignment, what we need is realignment.

A working definition of textbook “realignment”

Realignment is the process of ensuring that supplemental programs, assessments, and digital tools are not merely matched to the same standards as the core curriculum but are explicitly synchronized to the scope and sequence of the textbook in use.

Put differently: Realignment means shifting from the “these skills correspond to the same standard” to “this tool understands what teachers are teaching right now and responds accordingly.”

In other words, the alignment is:

1. Textbook-aware (knows the unit, lesson, and sequence of the adopted textbook).
2. Instructionally timed (mirrors what teachers are teaching this week).
3. Coherence promoting (presents information and resources in a manner that supports the personalizing of learning while maintaining curriculum fidelity and a focus on grade-level content).

Traditional alignment stops at mere skill association. In contrast, realignment fosters coherence by calling on supplemental resources to be reorganized, based on the textbook being used and the unit of focus.

This is why Renaissance’s newest work with textbook alignments, as well as our formal partnerships with core content providers, is so transformative. By the start of the 2026–2027 school year, our goal is to include this functionality for:

• 50% of the major ELA textbook series; and
• 80% of the major Math textbook series.

This means that once users have selected the textbook series they’re using, our systems will “realign” resources and data through that lens.

This functionality will be at the heart of our new Renaissance Intelligence system, which brings together assessment, instruction, practice, and curriculum alignment with trustworthy AI tools to promote greater coherence in every classroom.

Renaissance Intelligence: From data siloes to data intelligence

Educators do not set out to create incoherence. Instead, this happens almost naturally. It happens because, when school and district leaders design an instructional program, they tend to address one component at a time. “They spend time thinking through core instruction, then move on to Tier 2 and 3 instruction and its programs, and then focus on English Language development, and so on,” TNTP notes.

Unfortunately, “this siloed approach leads to discrete programs, isolated departments and division heads, and illogical instructional experiences for students,” TNTP concludes.

For this reason, it’s time to ask some key questions:

1. What if supplemental providers were part of the solution rather than contributors to the problem of incoherence?
2. What if, instead of providing stand-alone pieces of the overall instructional program, supplemental providers were willing to “realign” their offerings to the textbooks being used for core instruction?
3. What if siloed programs were replaced with a single, well-stocked and highly organized intelligence system?

This is what we’re building at Renaissance, to help schools and districts truly accelerate learning for all.
