By early July, a familiar worry surfaces in parent conversations across our Laoshan campus. Will the long summer holiday undo what our children worked so hard to build? It is a fair question, and the research on summer learning loss gives us honest answers, along with a calmer path forward than most parents expect.
At Qingdao No. 1 International School of Shandong Province, we sit with this question every year. Our families face a summer break that can stretch to ten or twelve weeks. Families weighing international schools in Qingdao often ask us about this very issue during admissions conversations. That is longer than the American calendar the research is built on, which is why summer slide education deserves a careful, evidence-led look, not another generic tip list.
The Summer Slide: One Month of Progress, Gone
Summer learning loss, often called the summer slide, describes the measurable drop in academic skills that can occur when children spend an extended break away from structured learning. The term entered mainstream research through the Cooper et al. 1996 meta-analysis, reviewed clearly in this Brookings Institution review of summer learning loss research, which found that students lost, on average, about one month of school-year learning over the summer.
More recent NWEA MAP Growth data shows a similar pattern. When children are tested in spring and again in fall, scores often stagnate or slip, especially in mathematics. Summer learning loss statistics from NWEA suggest math losses tend to run between 25 and 34 percent of school-year gains. Reading losses cluster between 17 and 28 percent.
We should note the honest caveat: some replication studies over the past decade have found smaller effects, and researchers continue to refine the picture. The direction of the risk, though, is well established. Math slides faster than reading. Older students tend to lose more than younger ones. That is enough to plan around.

Risk is not evenly spread. Some children glide through summer with skills intact, while others return in August needing weeks of review. Knowing the variables helps you plan.
Grade Level and Subject Matter
Older students carry more content, and more content means more to forget. Middle and high school learners typically show larger summer losses than early elementary children, particularly in procedural subjects.
Math decays faster than reading for a specific reason. Procedural fluency, the automatic recall of steps and facts, depends on regular practice. Without it, the Ebbinghaus forgetting curve does its quiet work. Reading comprehension, by contrast, is embedded in daily life through conversation, signs, screens, and books, so it degrades more slowly. Spaced repetition, even in short bursts, is what keeps math procedures from slipping.
Language Learners and Bilingual Families
For bilingual and English Language Learning students, summer carries a double edge. Both first-language literacy and English acquisition can weaken without exposure. This matters deeply for our community. Many of our families juggle English at school, Mandarin at home, and sometimes a third language with grandparents.
The National Summer Learning Association has documented how the academic achievement gap between higher- and lower-resource families tends to widen across summers. Access to books, structured activities, and conversation-rich environments matters, and the link between socioeconomic status and learning shows up most sharply during long breaks. We frame this through a growth mindset lens, borrowing from Carol Dweck’s work: risk factors are things you can act on, not fixed traits.
What a Skills-Maintenance Week Actually Looks Like
The most useful thing we can offer is a realistic weekly rhythm. Not a curriculum. Not a summer packet. A shape for the week that a busy family can actually keep, built from summer learning loss activities that are simple, cheap, and repeatable.
A Sample Five-Day Summer Rhythm
Here is what a light-touch week looks like, grounded in John Hattie’s visible learning evidence on spaced practice:
- 20 to 30 minutes of reading, five days a week, in a book the child chose
- 15 minutes of math practice, four or five days a week, ideally applied to something real
- One open-ended project per week, such as a travel journal, a family recipe scaled up, or a small science observation
- One social or physical activity most days, such as swimming, team sport, or a community outing
That is under an hour a day. Compare it to the six or seven hours of school, and it feels almost gentle. Yet the research on spaced retrieval says this is the range where maintenance happens.
Active Retrieval vs. Passive Screen Time
Not all practice is equal. Watching an educational video feels productive, but the brain is largely a passenger. Retrieval practice, where the child pulls information out of memory, is what strengthens learning. Ask your child to explain the chapter they just read. Have them estimate the bill at dinner before the receipt arrives. Let them teach you a math trick.
A spaced-repetition flashcard app used for ten minutes beats thirty minutes of a passive game. The difference is whether the mind is producing or consuming.
When Rest Is the Right Call
Summer is also for rest. Executive function, the mental scaffolding that supports focus and self-regulation, is rebuilt through unstructured time, play, and boredom. Brookings researchers have made this point clearly. A child who reads for pleasure, spends an afternoon building something odd in the garden, or simply lies on the grass thinking is not falling behind. They are recovering.
A good summer is one where our children grow academically and as whole people. Rest and learning are not in conflict.
Reading and Math: Subject-Specific Strategies That Work
To prevent summer learning loss in the two subjects that matter most for early academic momentum, target reading and math with different tools. One thrives on choice. The other thrives on context.
Keeping Reading Gains Alive: Summer Slide Reading Strategies
The single strongest intervention for summer reading is choice. When children pick their own books, they read more, and volume drives fluency. NSLA research has repeatedly shown that self-selected reading outperforms assigned summer packets. Graphic novels count. Sports biographies count. A series they cannot put down counts most of all.
For families who want a sense of progress, the simplest check is whether a child can read a slightly-harder-than-comfortable book aloud with expression and understanding, rather than stumbling word by word. Reading fluency norms exist for each grade if you want a formal benchmark, but for a summer at home, smooth and confident reading is the signal that matters.
Summer Slide Math: Skills Without the Worksheets
Math survives summer when it lives in the world. Budgeting a family day out. Doubling a recipe. Measuring a garden bed. Calculating tip and exchange rates on holiday. These moments do more for procedural fluency than a photocopied packet because they carry meaning.

Talk to admissions →For older students preparing for AP courses in China such as AP Calculus or SAT math, a short daily set of five to ten mixed problems, spaced across the week, keeps the machinery running. Our students who sit AP exams in May tell us the same thing every year: the students who kept a light math habit over summer felt sharper when school resumed.
Maintaining Chinese Language Literacy
Chinese literacy deserves the same care as English. For our bilingual families, twenty minutes of Chinese reading a day, whether picture books, chapter novels, or age-appropriate news, protects gains built during the school year. Writing a short journal entry in Chinese once or twice a week adds active production to passive reading. This is not extra work. It is the second half of a bilingual education.
How Schools Can Reduce the Slide Before It Starts
A school’s structure matters as much as anything a family does at home. Several features of our approach are designed, deliberately, to support summer learning loss prevention before June even arrives.
Formative assessment before the break. As a WASC and CIS dually accredited school, and an active member of EARCOS, we use formative assessment data throughout the year, including NWEA-style measures, to identify students who need targeted support before June. Personalised reading lists and skill focus areas go home with families, not generic packets.
Inquiry-based learning as a protective factor. When students learn through questions and projects rather than isolated facts, knowledge is networked. Networked knowledge transfers, and it survives breaks. Hattie’s work on transfer of learning supports this, and it is why our inquiry-based approach to learning, rooted in inquiry-based learning across every division, matters beyond test scores.
Social-emotional foundations that travel. Our Leader in Me programme, aligned with the CASEL framework, builds self-management and goal-setting habits in our students from Early Childhood upward, helping them Learn, Lead, and Live well beyond the classroom. A Grade 5 student who has learned to set a weekly goal and track it is a Grade 5 student who can keep a summer reading habit alive without a parent hovering. Leader in Me and social-emotional learning shape the summer as much as any subject.
Summer bridge programs and camp options. NSLA evidence suggests that five or more weeks of high-quality summer learning loss programs produce measurable gains. Our summer camps and enrichment programmes, along with the year-round after-school activity programme, give families a school-affiliated option built by teachers who know our curriculum.
Teacher communication. End-of-year conferences let our teachers hand off specific, personalised guidance for each child. Not a checklist. A conversation.
Common Questions Parents Ask About Summer Learning Loss
Is summer learning loss a real thing? Yes, though with nuance. The core finding, an average one-month loss in school-year learning, has held up across decades of research. Some recent replication studies show smaller effects. Math loss is the most consistent and best-documented risk, especially at older grade levels.
What percentage of learning is lost over the summer? On average, 25 to 34 percent of school-year math gains and 17 to 28 percent of reading gains. These are averages. Your child’s outcome depends on grade, subject, and what happens between June and August.
Which subjects are hit hardest by the summer slide? Math procedural fluency shows the steepest and most consistent losses, roughly 25 to 34 percent of school-year gains. Reading follows at 17 to 28 percent. Writing mechanics and foreign language acquisition are also vulnerable, though less studied.
What is it called when kids lose knowledge over the summer? Educators usually call it summer learning loss, the summer slide, or summer setback, and the three terms mean the same thing: the skills, especially in reading and maths, that fade when they go unused across a long break. It is well documented and entirely normal, which is also why it is preventable. A little structured practice through the holiday, rather than a frantic catch-up in September, is what keeps a child steady, and the rest of this guide is about how to do that without turning summer into school.
How to prevent summer learning loss day to day? Twenty to thirty minutes of reading plus fifteen minutes of math practice, most days, is the evidence-supported minimum. Quality of practice matters more than quantity. Active retrieval beats passive review.
Do international schools in China experience the same summer slide? The risk exists everywhere, though structural features help. A longer school year, small class sizes, inquiry-based continuity, and pre-summer formative assessment all reduce risk. They do not eliminate it. Family habits still matter.
Should I enrol my child in a summer programme? If your child would benefit from structure, social connection, or targeted practice, a well-designed programme helps. Look for one that is accredited or school-affiliated, uses assessment data to personalise, and balances academics with wellbeing.
Choosing a Summer Plan That Fits Your Family in Qingdao
Most families do best somewhere in the middle. A fully unstructured ten-week summer risks skill loss, particularly in math. A full academic summer school risks burnout and misses the developmental value of rest. The middle path, a light-touch maintenance plan plus one or two enrichment experiences, works for most children and is the most sustainable way to prevent summer learning loss without sacrificing a genuine break.
Three questions to ask about any summer programme:
- Is it accredited, school-affiliated, or led by qualified educators?
- Does it use assessment or formative data to personalise the experience?
- Does it balance academic work with physical activity, creative play, and wellbeing?
Our summer camps and after-school programmes are designed to meet all three. They also carry continuity with the school-year curriculum, so a child who joins in July returns in August feeling connected rather than restarted. That continuity is part of what makes QISS a joyful place to learn and grow across all four seasons, not just the school year.
If you are weighing options for your child this summer, or thinking ahead to next year, we would be glad to talk.

Is summer learning loss a real thing?
Yes, the research consistently shows an average one-month loss in school-year learning over summer, with math losses most pronounced at 25 to 34 percent of annual gains and reading losses at 17 to 28 percent. Some recent studies find smaller effects, but the direction of risk is well established.
What percentage of learning is lost over the summer?
On average, students lose 25 to 34 percent of school-year math gains and 17 to 28 percent of reading gains, though these are averages that vary by grade level, subject, and what families do during the break.
What is it called when kids lose knowledge over the summer?
We call it summer learning loss, the summer slide, or summer setback, all referring to the same phenomenon: skills in reading, math, and writing that fade when unused across a long break, which is entirely normal and preventable.
Which subjects are hit hardest by the summer slide?
Math procedural fluency shows the steepest losses because it depends on regular practice and automatic recall, while reading degrades more slowly since it is embedded in daily life through conversation and screens. Writing mechanics and foreign language acquisition are also vulnerable.
Does summer learning loss affect all students equally, or are some groups more vulnerable?
No, older students lose more than younger ones, and the achievement gap between higher- and lower-resource families tends to widen over summer because access to books, structured activities, and conversation-rich environments matters significantly.
How much time each day does a child actually need to maintain skills over summer?
We recommend 20 to 30 minutes of reading five days a week plus 15 minutes of math practice four or five days a week, totaling under an hour daily, which research on spaced retrieval shows is the range where maintenance happens.
What low-pressure activities genuinely protect reading and math gains?
For reading, self-selected books (including graphic novels and series) drive fluency through volume, while for math, real-world contexts like budgeting a day out, doubling recipes, or calculating tips preserve procedural fluency far better than worksheets because they carry meaning.
How does an international school's year-round support structure reduce summer slide risk?
We use formative assessment before June to identify students needing support, deliver personalized reading lists rather than generic packets, build inquiry-based learning that transfers across breaks, develop self-management habits through our Leader in Me programme, and offer school-affiliated summer camps with curriculum continuity.
