PISA Reading Decline and the Literacy-First Fixes Gaining Ground

Of all the subjects PISA measures, reading fell the hardest. That is a clue about the cause, and about the cure.

The PISA results and the reading decline they confirmed in 2026 have pushed one debate back to the center of education: how children are actually taught to read. Across wealthy countries, average reading scores dropped roughly 28 points between 2015 and 2025, close to a year and a half of learning. Math slipped too, and science held steadier, but reading is where the erosion is sharpest and most visible. In response, a growing number of educators are rallying around what they call literacy-first instruction, and the phrase has a specific meaning worth understanding.

In Brief

• Reading declined more sharply than other subjects in PISA 2025, deepening a slide that began before the pandemic.
• Reading is uniquely exposed because it depends on both sustained attention and a solid decoding foundation, and both have weakened.
• The literacy-first response centers on the science of reading and structured literacy, which favor explicit, systematic phonics over guessing-based methods.

Why Reading Fell the Hardest

Reading is fragile in a way arithmetic is not. It leans on two things at once: the mechanical skill of decoding words, and the stamina to stay with a text long enough to understand it. When either weakens, comprehension suffers, and lately both have.

The attention side gets most of the headlines, and the sharp reading decline in PISA 2025 arrived in the same decade that phones rewired how teenagers spend their time. But there is a quieter factor that educators keep raising: for years, many schools taught reading using methods that never gave weaker readers a reliable way to decode words in the first place.

What “Literacy-First” Actually Means

Literacy-first is shorthand for teaching aligned with the science of reading, a large body of research on how the brain learns to read. It usually shows up in classrooms as structured literacy, and it rests on five connected skills: phonemic awareness, phonics, vocabulary, fluency, and comprehension.

The core idea is explicit instruction. Instead of hoping children absorb reading through exposure, structured literacy teaches decoding directly and systematically, sound by sound, in a deliberate order. Comprehension and vocabulary are taught alongside, so a student builds both the ability to read words and the knowledge to understand them.

The Shift Away From Balanced Literacy

This is where the so-called reading wars come in. For decades, many schools used balanced literacy or whole-language approaches, which lean on context clues and encourage children to guess unfamiliar words from pictures or sentence flow. It works fine for kids who crack the code easily. It leaves struggling readers stranded.

Actually, that distinction is the whole argument. Research on systematic phonics has repeatedly found it gives beginning, at-risk, and struggling readers a better shot at proficiency than guessing-based methods. That evidence is why a wave of schools and even entire states have rewritten their reading curricula in recent years, moving deliberately toward structured literacy.

The most cited proof comes from Mississippi. Facing some of the weakest reading scores in the country, the state rebuilt its early instruction around systematic phonics, intensive teacher training, and early screening for struggling readers, then tied promotion to reading progress. Its fourth-grade reading results climbed sharply enough that education watchers began calling it the Mississippi turnaround, and it stands as evidence that these declines can be reversed with the right instruction.

What Actually Helps

The good news is that reading responds to instruction, which means a decline is reversible. The moves that show up across successful programs are not exotic:

• Teach phonics explicitly and systematically, especially in the early grades, rather than leaving decoding to chance.
• Protect daily time for sustained, distraction-free reading, so stamina has room to grow.
• Build vocabulary and background knowledge on purpose, since comprehension depends on both.
• Screen early for reading difficulty, because catching a struggling reader in first grade beats remediation in fifth.

What To Know

• Reading declined more sharply than other subjects in PISA 2025, extending a pre-pandemic slide.
• Reading depends on both decoding and attention, and weakness in either lowers comprehension.
• Literacy-first means the science of reading and structured literacy, built on explicit, systematic phonics.
• The practical fixes are direct phonics, daily reading time, deliberate vocabulary work, and early screening.

Frequently Asked Questions

Why is reading declining faster than math or science?

Reading relies on both decoding skill and sustained attention, and both have weakened, partly through changing habits and partly through instruction methods that left weaker readers without reliable decoding. That combination hit reading harder than other subjects in PISA 2025.

What is the science of reading?

It is a large body of research on how people learn to read, pointing to five connected skills: phonemic awareness, phonics, vocabulary, fluency, and comprehension. Structured literacy is the classroom approach built on it.

What is structured literacy?

Structured literacy teaches reading explicitly and systematically, including direct instruction in how to sound out words, alongside vocabulary and comprehension. It contrasts with methods that expect children to absorb reading mainly through exposure.

What are the reading wars?

They are the long debate between phonics-based instruction and whole-language or balanced-literacy approaches that emphasize guessing words from context. Evidence favoring systematic phonics for struggling readers has driven many schools back toward explicit instruction.

Can parents help reverse a reading decline at home?

Yes. Reading aloud together, protecting daily distraction-free reading time, talking about words and their meanings, and flagging early reading struggles to teachers all support the same skills schools are targeting.

What To Do Next

If the PISA reading numbers landed as one more piece of bad news, the more useful response is to ask a concrete question: how is reading actually taught where your children learn? The gap between guessing at words and decoding them is the difference the data keeps pointing to. For related coverage, browse Wayodd’s Education and Family & Personal sections. Reading is a taught skill, which is the most hopeful fact in the whole report, because taught skills can be taught better.
