What research says about homework and children
TL;DR
Research shows that homework has no measurable effect for children under 3rd grade — and a moderate positive effect from the middle grades. The key is not the amount, but the framework: fixed time, quiet place, no screen, and a parent who supports without taking over.
Homework can feel like a daily power struggle. The child would rather play. You want it done. And you’re not even sure if it really helps. The short answer is: it depends on the child’s age. Research is surprisingly clear on this point — and it’s not the answer most parents expect. Let’s go through what we actually know, and what you can do to make homework time work instead of being a daily battle.
What does research say about homework? Harris Cooper’s meta-analysis
The most cited research on homework is Harris Cooper’s meta-analysis from Duke University — and it is surprisingly nuanced.
Harris Cooper from Duke University has reviewed over 180 studies on the effect of homework on school results. His conclusion, published in Review of Educational Research, is clear:
- Lower grades (0th–2nd grade): No measurable effect on academic results. Homework can even create a negative association with school if it pressures the child.
- Middle grades (3rd–6th grade): Moderate positive effect if the amount is appropriate (max 30–60 minutes daily).
- Upper grades (7th–9th grade): Clear positive effect — up to a certain point. More than 2 hours daily results in diminishing returns.
Cooper formulated the so-called "10-minute rule": 10 minutes × grade level per day. A student in 1st grade: 10 minutes. A student in 5th grade: 50 minutes. A student in 9th grade: 90 minutes.
The Danish public school and homework
In Denmark, there is no legislation on the amount of homework — it is up to each individual school and teacher.
With the 2014 public school reform, the school day became longer. This meant that for many schools, the amount of homework decreased. But practices vary enormously from school to school and from teacher to teacher. There is no national standard for the amount of homework in Denmark.
The Ministry of Education recommends that homework is meaningful — that it reinforces something covered in class and is not just routine tasks. Many teachers today are aware not to overdo it, especially in the youngest grades.
If you feel your child has too much or too little homework, a good dialogue with the teacher is always the first step.
What makes homework time better? The four frameworks that work
The framework around homework time matters more than the amount of homework.
It’s not just what the child does that matters — it’s also when, where, and under what conditions:
- Fixed time: The same time every day reduces resistance. The brain knows what’s coming — and accepts it more easily. Many families find that a fifteen-minute snack break after school, followed by homework, works well.
- Quiet place: A place without distractions. Not necessarily the child’s own room — many children work better at the kitchen table, close to a parent.
- No screens: Studies show that even the presence of a turned-off mobile phone reduces cognitive capacity. Keep screens out of the homework area.
- Light snack beforehand: Blood sugar drops during the school day. An apple, a piece of bread, or a glass of milk before starting homework improves concentration.
Parents’ role: support vs. take over
The best parent during homework time is present but withdrawn — available for questions, but lets the child do the work.
It’s tempting to help too much. The child struggles with a task, you can see the solution, and it’s faster just to show it. But research shows that parents who do the homework for the child significantly reduce the learning effect.
A good rule of thumb: ask questions instead of giving answers. "What do you think the answer is?" "What does your book say about it?" "What do you already know about this topic?" This guides the child to think for themselves — and that is what creates the learning effect.
Avoid sitting next to your child the entire homework time. Be available, but let the child call on you. This builds independence and confidence.
When are homework problems a sign of something else?
If homework time is a daily crisis, it’s worth investigating if there is an underlying cause.
All children have bad homework days. But if resistance is constant and intense, it may signal something beyond tiredness and laziness:
- Learning difficulties: Dyslexia, dyscalculia, or attention difficulties (ADHD) can make homework disproportionately hard. Contact the school if you suspect this.
- Anxiety: Performance anxiety can show as homework refusal. The child fears making mistakes more than being unwilling.
- Academic underperformance: If the child doesn’t understand what is covered in class, homework can feel meaningless and overwhelming.
- Social distress: School refusal and homework resistance can be symptoms of social problems in the class.
Talk to your child’s teacher and consider PPR counseling if patterns persist. See our inspiration blog for tips on learning at home.
Good habits that support all learning — not just homework
Homework is just one part of a child’s learning environment. What happens outside homework time matters just as much.
Research on children’s academic performance consistently points to a handful of factors beyond homework:
- Reading for pleasure: Children who read daily perform better in all subjects. Give them time and freedom to read what they want.
- Conversation about the world: Families who talk about news, nature, food, and society give children a rich conceptual framework to hang knowledge on.
- Sleep: A child who sleeps too little remembers and learns worse. Sleep is not a luxury — it is a learning tool.
- Movement: Exercise improves concentration and memory. A run or active play before homework is not wasted time — it’s preparation.
Homework and family life — set boundaries that suit you
There is no universal homework plan. Find what works for your family — and be consistent with it.
Some families find it best to let the child do homework alone in their room. Others know the child functions better at the kitchen table with a parent nearby. Some children perform best right after school, others need free time first.
Give it time. It typically takes a couple of weeks to establish a new homework routine. And remember that a good homework evening starts in the kitchen: cooking together before homework, with MINI Family's kitchen set, signals togetherness and calms the child — a gentler transition than going straight from school to schoolwork.

Homework helps — but not for the youngest, and not in unlimited amounts. What matters most is not the number of tasks, but the quality of the environment. Fixed time, quiet place, a parent who supports without taking over — and enough sleep and exercise the rest of the day.
And if homework time is a daily battle: investigate if there is something beneath the surface. It is never just laziness.
Frequently Asked Questions
Does homework help children in early school years?
According to Harris Cooper's meta-analysis from Duke University, there is no measurable positive effect of homework for children under third grade. For the youngest, routine and reading at home are more important than formal homework.
How much homework should my child have per day?
A good rule of thumb is the "10-minute rule": 10 minutes × grade level per day. A third-grade student should therefore have a maximum of 30 minutes daily. Beyond this amount, homework rarely provides additional learning benefits for younger children.
What do I do if my child refuses to do homework?
Start by investigating the cause. Is it tiredness, frustration, tasks that are too difficult, or something social? A fixed time and a gentle routine help. If the resistance is consistent and intense, it is worth talking to the teacher about possible academic difficulties or well-being issues.
May I help my child with their homework?
Yes — but there is a difference between helping and taking over. Be available, ask questions, and guide the child to think for themselves. Avoid giving the answers directly, as it reduces the learning effect and the child's confidence in their own abilities.
What is the best time for homework?
It varies from child to child. Many do best with a short break after school — snack, free play — and then homework. Try different times and find what works in your family. The most important thing is consistency: the same time every day.
