Many adolescents are not just struggling to comprehend text; they are struggling to stay with it long enough to make meaning. If secondary schools want better reading outcomes, rebuilding stamina has to come before chasing test scores.
The quiet problem behind weak reading scores
When middle and high school students say, "I hate reading," they are not always rejecting stories, ideas, or learning. Often, they are naming a loss of endurance. They have trouble sustaining attention through a chapter, a primary source, a science article, or even a few pages of demanding text. They tire quickly, lose the thread, and begin to associate reading with frustration.
That matters because reading achievement is not built on skill alone. It also depends on stamina: the capacity to read with focus for long enough to understand, question, connect, and remember. In secondary school, where texts become denser and teachers expect more independence, weak stamina can quietly undermine everything from history discussion to lab reports to algebra word problems.
The national picture is sobering. On the 2024 NAEP, often called the Nation's Report Card, average reading scores for both 8th graders and 12th graders remained below pre-pandemic levels. NAEP has also long shown wide gaps by income, race, disability status, and reading performance level. These results do not mean teachers are failing. They reflect a complicated reality: interrupted learning, chronic absenteeism, device-saturated attention, uneven early literacy foundations, staffing shortages, and the simple fact that many adolescents now spend less time reading sustained text than schools still require them to handle.
Why endurance matters in grades 6-12
Secondary educators know the pattern. A student can decode adequately, contribute smartly to discussion, and still fall apart when asked to read independently for 20 minutes. Another student may do fine with short excerpts but shut down when faced with a novel, a Supreme Court opinion, or a multi-page article. These are not small issues of motivation. They are barriers to access.
Reading endurance is the bridge between foundational skills and academic performance. Students need it to persist through unfamiliar vocabulary, nested sentence structure, text features, and moments of confusion. Without that persistence, comprehension breaks down before it has a chance to develop.
International comparisons offer a useful reminder here. PISA, the Programme for International Student Assessment run by the OECD, has consistently shown that reading literacy involves not only decoding and recall but also the ability to engage with longer, more complex texts and use them purposefully. High-performing systems such as Singapore, Estonia, Finland, and parts of Canada differ in many ways, but they tend to treat reading as a whole-school responsibility and build habits of independent reading, discussion, and knowledge-rich instruction over time. There is no magic national model to import. But there is a common lesson: strong reading outcomes are built through steady practice, not quick fixes.
What has made stamina harder to build
It is tempting to frame the problem as student laziness or screen addiction, but that is too simple and not especially helpful. Adolescents are reading all the time in some formats. The issue is that digital reading habits often reward skimming, scanning, and rapid switching. School reading, by contrast, asks for slower processing and sustained attention.
Students also arrive in secondary classrooms with very different histories. Some had rich read-alouds, strong phonics instruction, and years of successful independent reading. Others experienced fragmented instruction, limited access to books, language barriers, or undiagnosed learning needs. Since the pandemic, many schools have also reported lower attention spans, greater anxiety, and less tolerance for productive struggle.
Then there are the structural constraints educators face. Class periods are short. Curricula are crowded. Teachers are under pressure to cover standards, prepare students for tests, and support a very wide range of needs. Secondary schools often have fewer routines devoted to actual reading volume than elementary schools do. By the time students reach grade 7, 9, or 11, adults may assume stamina should already exist. For many students, it does not.
Stamina is not separate from instruction
Rebuilding reading endurance does not mean assigning silent reading and hoping for the best. Stamina grows when students can read with enough success to keep going. That means volume matters, but so does support.
Students need texts that are worthy, coherent, and appropriately challenging. They also need scaffolds that preserve dignity: brief pre-teaching of concepts, strategic vocabulary work, guided annotation, chunked reading goals, and chances to talk before writing. In other words, stamina develops through instruction that helps students experience what successful sustained reading feels like.
This is especially important in secondary content areas. Adolescents do not only need better reading classes; they need more opportunities to read meaningfully in science, social studies, career and technical education, and the arts. A history teacher helping students persist through a speech, or a biology teacher modeling how to unpack a dense explanation, is also building literacy endurance.
What schools can do realistically
The first step is to protect time for actual reading. Not worksheet completion. Not just test-prep passages. Reading. Even 10 to 15 minutes of sustained, accountable reading several times a week can begin to reset expectations, especially when students see that adults value the habit enough to make room for it.
Second, schools can measure more than proficiency. Track whether students can sustain reading for increasing amounts of time, finish whole texts, and discuss them with evidence. These indicators are not a replacement for achievement data, but they can show growth earlier and more encouragingly.
Third, build text access. Classroom libraries, school library staffing, audiobook options, high-interest nonfiction, graphic novels, verse novels, multilingual texts, and culturally relevant selections all matter. Adolescents are more likely to build endurance when they can sometimes choose texts that feel both accessible and meaningful. Choice is not the enemy of rigor; it is often the path into it.
Fourth, teach teachers how to support reading without turning every class into English. Content-area literacy strategies should be practical and light enough to use: modeling how experts read in the discipline, setting a clear purpose, stopping for brief summaries, and teaching students what to do when comprehension breaks down.
Fifth, intervene early and specifically. Some students need stamina-building routines. Others need foundational decoding and fluency support that should not have ended in elementary school. Secondary intervention works best when it is targeted, scheduled consistently, and delivered without stigma.
A humane path forward
If schools want stronger adolescent literacy, they should absolutely care about scores. But scores are the lagging indicator. Before many students can demonstrate comprehension on an assessment, they have to rebuild the capacity to stay with text in the first place.
That work is not glamorous. It requires repetition, patience, and protected time in a schedule that already feels impossible. It asks secondary schools to resist the urge for one more program and instead strengthen daily reading routines across classrooms. It also asks adults to believe that adolescents who have drifted from reading are not lost causes. Many are one successful reading experience away from trying again.
A realistic agenda for grades 6-12 might look like this: protect sustained reading time, increase access to engaging texts, use simple scaffolds for complex reading, train all teachers in basic disciplinary literacy, and provide targeted intervention for students with deeper gaps. None of those steps is easy. All of them are doable.
Stamina before scores is not a slogan. It is a practical reminder that better reading outcomes begin with helping students read longer, with more confidence, and with less fear. When schools rebuild that endurance, comprehension has a chance to follow.
