What happened
Recent recovery data is sending a mixed message: many schools and districts are improving, but the recovery is uneven enough that learners can still arrive at new lessons with missing prerequisite knowledge.
The clearest 2026 signal comes from the Education Scorecard, a collaboration involving Harvard’s Center for Education Policy Research, Stanford’s Educational Opportunity Project, and Dartmouth faculty. Its 2026 findings describe a post-pandemic math rebound, early signs that comprehensive literacy reforms are helping reading, and large variation among districts that look similar on paper. The project also identifies 108 districts with unusually large reading and math gains compared with matched peers.
A related Stanford summary of the same work adds important context: achievement had been weakening before COVID-19, 8th-grade reading scores on national assessments are now at their lowest point since 1990, and chronic absenteeism remains elevated. Stanford reports that 23% of students were chronically absent in the 2024-25 school year, down from the pandemic peak but still well above the pre-pandemic rate of 15%.

NWEA’s February 2026 recovery study gives the school-level picture. Using MAP Growth data from more than five million students across 9,326 public schools, NWEA found that about one in three schools had recovered in either math or reading, while only one in seven had recovered in both. The study defined recovery as fall 2024 average achievement matching or exceeding fall 2019 levels. See the release here: NWEA on uneven academic recovery.
Curriculum Associates’ 2025 State of Student Learning report points in the same direction. Based on millions of i-Ready assessments, the report says national achievement has remained mostly flat since spring 2023, many students have not returned to pre-pandemic achievement levels, and gaps have widened for lower-performing students.

Why it matters
For classrooms, tutoring, and independent study, the practical issue is not only whether a student is “behind” in a broad subject. The sharper question is which prerequisite ideas are missing right now.
A learner can appear ready for the next unit because they completed last year’s course, earned a passing grade, or made average growth on an assessment. But prerequisite knowledge is not stored as a course label. It is made of specific pieces: multiplication facts needed for fractions, fraction concepts needed for ratios, sentence-level decoding needed for comprehension, vocabulary needed for inference, or background knowledge needed to understand a science text.
That is why uneven recovery matters. If one school has recovered in math but not reading, if one district has rebounded while a similar district has not, or if lower-performing students are falling farther behind while higher-performing students recover, a single pace guide can become misleading. Some students need acceleration into grade-level work. Others need a quick rebuild of the exact older knowledge that the new work depends on.
The danger is over-remediation. If every gap leads to weeks of broad review, learners lose access to current material and motivation drops. The opposite danger is pretending the gaps are not there. When students practice advanced tasks without the building blocks, working memory gets overloaded, mistakes look careless, and feedback becomes too general to help.
The learning conclusion
The best response to recovery data is targeted prerequisite checking, not a permanent slowdown. Before moving into a new skill, teachers, tutors, parents, and self-learners should ask: what must the learner be able to retrieve or use quickly for this lesson to make sense?
- Diagnose the specific gap. Use two to five short questions before a lesson. They should test the exact knowledge the next task requires, not the whole previous unit.
- Separate recall from recognition. A multiple-choice review can hide weak memory. Include at least one prompt where the learner must explain a step, define a term, solve from a blank page, or retrieve an example without seeing options.
- Sequence review just in time. Put the missing prerequisite immediately before the new task. Review fractions before ratios, paragraph structure before essay revision, or decoding patterns before a dense reading passage.
- Keep review short and reusable. A ten-minute rebuild is often better than a full reteach. Use a worked example, one guided attempt, and one independent retrieval check.
- Move ahead after evidence, not after time. If the learner can retrieve the prerequisite and use it in a fresh problem, continue. If not, adjust the next task before adding more volume.
- Track recurring prerequisites. When the same gap appears across several lessons, it deserves a planned mini-cycle of spaced retrieval, not a one-time reminder.
Recovery reports are useful because they warn against teaching from averages. The practical learning move is smaller and more precise: identify the prerequisite, check it quickly from memory, repair it close to the moment of use, and then return to meaningful grade-level work.
