We’ve Misdiagnosed Adolescent Reading Struggles
In a recent Education Week report, Stephen Sawchuk highlights that large numbers of middle and high school students struggle to read grade-level texts with confidence and fluency. The article notes that training for adolescent literacy is limited, while screening and intervention taper off after elementary school, leaving teachers to close years of gaps in content-heavy courses.
As a secondary literacy leader, I have seen my fair share of programs and initiatives designed to address this issue. The instinctive response from many districts is often more intervention time, or more “personalized” programs—despite their mixed evidence. But before we expand screening and small-group remediation yet again, we should ask: Are we solving the instructional problem, or simply treating the symptoms?
Reading comprehension depends on understanding a text. The most widely supported model in reading research explains comprehension as the interaction of word recognition and language comprehension: students must be able to decode and read fluently and possess the vocabulary, background knowledge, and language proficiency to understand complex text. Comprehension is built from language and knowledge. It is not assembled from isolated skills.
Yet much of our literacy system operates as if it were.
Over the past two decades, three reforms have reshaped literacy instruction: strategy instruction, standards-based accountability, and an expanding push for differentiation. Together, they have encouraged classrooms to revolve around the visible moves of good readers—find the main idea, draw an inference, cite textual evidence. Yet these are signs of comprehension, not the cause of it. Strategy instruction can help students navigate text, but it cannot create the vocabulary, knowledge, and language proficiency that comprehension ultimately depends on.
The Common Core literacy standards were designed to describe what proficient readers can do across texts and disciplines—not explain how comprehension develops. They were never intended to diagnose why comprehension breaks down. Yet performance descriptors have become instructional targets, reinforcing the assumption that practicing standards improves reading outcomes. In mathematics, repeated exposure to problem types can strengthen procedural fluency. Reading comprehension does not operate that way; it depends on background knowledge, vocabulary, and language structures that build over time. Unlike math and science standards, which specify particular content and procedures, many ELA standards describe generalized reader behaviors—“analyze,” “infer,” “cite evidence,”—without specifying the underlying knowledge or language students must bring to the task. Practicing “finding the main idea” across disconnected passages does little to build the vocabulary and knowledge that makes main ideas discernible in the first place.
In secondary classrooms, the challenge intensifies. Students must grapple with discipline-specific texts dense with technical vocabulary, assumed knowledge, and complex syntax. A struggle to cite textual evidence may reflect those language demands—not an absence of skill. When the standard becomes the diagnosis, we risk mistaking the symptom for the cause. Without diagnosing those underlying barriers, skill reteaching misses the mark.
That misdiagnosis often leads to predictable responses. Differentiation, in theory, promises precision and responsiveness; in practice, it often encourages practices that are counterintuitive to improving reading gains. Well-meaning teachers often ask me if leveling a text to a student’s “reading level” is an appropriated support. The instinct is understandable: if a text feels too hard, make it easier. But a growing body of research suggests that routinely replacing grade-level texts with simplified versions may limit students’ exposure to the very vocabulary, syntax, and domain knowledge they need to catch up. The question is not whether students need support. It is whether lowering the text builds the language systems required to read the next one.
In many secondary classrooms, students spend significant portions of the period working independently—annotating, responding to prompts, or completing digital tasks—while explicit modeling of how to unpack complex language happens sparingly. Teacher education programs and professional development initiatives increasingly emphasize a facilitative approach to instruction, where students are left to “grapple with complex ideas” independently. Yet research consistently shows that struggling learners benefit from explicit modeling, guided practice, and feedback before independent application. When classrooms prioritize facilitation without sustained language modeling, struggling readers may be left without the instructional support needed to develop comprehension.
At the secondary level, reading is inseparable from content. Students must interpret scientific explanations, historical arguments, and complex literature. Accessing complex text requires more than strategy: deliberate scaffolding, attention to morphology and academic vocabulary, and intentional background building through strategic questioning and well-sequenced texts. Struggling readers don’t need another rotation on citing evidence. They need sustained engagement with complex ideas and explicit instruction that builds shared understanding over time. When teachers deliberately build knowledge, model disciplinary thinking, and support students through complex texts together, fewer students require intensive remediation later.
Strengthening adolescent literacy will require confronting capacity gaps: evidence for secondary interventions remains mixed, and many programs emphasize discrete skills rather than coherent knowledge and language development. Most secondary teacher preparation programs prioritize content expertise, leaving teachers with limited formal training in how reading comprehension develops. At the same time, an instructional culture that leans heavily toward facilitation and independent “grappling” can leave struggling readers without the explicit modeling and guided practice they need. When students are labeled two or three grade levels behind, remediation outside the classroom can seem like the only option. But before expanding intervention structures, we should examine what happens inside core instruction. If large portions of instructional time prioritize independent task completion over explicit language and knowledge building, the persistence of reading gaps becomes less surprising.
As policymakers consider how to strengthen adolescent literacy, the answer is not simply more intervention blocks or more granular skill reports. Reading difficulties should not be identified by the standard a student missed, but by the component of comprehension that is breaking down—word recognition, language comprehension, or background knowledge. These are not interchangeable problems, and they cannot be solved with the same skill worksheet. If we want different outcomes, we must design classrooms that deliberately build knowledge and language—not just rehearse the visible moves of good readers. Adolescents do not need more standards-based re-teaching; they need richer instruction.
