The Homework Question Nobody Wants to Answer

Every weeknight, in kitchens across the country, the same scene plays out. A child stares at a worksheet. A parent hovers. Someone raises their voice. By bedtime, everyone is exhausted and nobody feels good about what just happened.

A 2025 study from Tsinghua University recorded 475 hours of homework sessions across 78 families. The researchers found seven distinct types of parent-child conflict that regularly erupted during homework time, with disagreements over the actual content being the most common. Even praise backfired - parents who offered general encouragement like "well done" without being specific about what was good actually triggered more arguments, not fewer.

If homework is causing this much friction, it had better be worth it academically. So is it?

What the evidence actually says

The short answer is: it depends on how old your child is.

For primary school children, the academic benefit of homework is close to zero. Harris Cooper's landmark meta-analysis at Duke University - the most cited homework study in the world - found that for children in primary school, there was almost no link between doing homework and doing better academically. The Education Endowment Foundation, which reviews evidence for UK schools, puts the benefit at roughly two months of extra progress over an entire year. That is a tiny gain, and it comes with a big asterisk: the homework has to be high quality, focused, and short. The kind of worksheet that gets sent home on a Friday and forgotten about until Sunday evening does not qualify.

For secondary school students, the picture changes. Cooper's research found a clear positive link between homework and achievement from Year 7 onwards, though even here there are limits. After about two hours a night, the returns drop off sharply. More homework beyond that point does not mean better results.

The 10-minute rule and what it gets wrong

You might have heard of the "10-minute rule" - the idea that children should do roughly 10 minutes of homework per year group. So a Year 3 child would do 30 minutes, a Year 6 child would do 60. It comes from Cooper's work and it is widely repeated.

But there is a problem with applying this to younger children. The research does not show that 30 minutes of homework helps a Year 3 child learn more. It shows that 30 minutes is roughly the upper limit before homework starts actively doing harm - through stress, through lost free time, through battles with parents. That is a very different thing. The rule tells you the ceiling, not the target.

Since 2012, the UK government has not set any official guidelines on homework. The decision sits with individual headteachers. Some primary schools have moved to a reading-only homework policy. Others have dropped homework entirely. There has been no measurable drop in standards at these schools.

What gets lost in the argument

The homework debate tends to focus narrowly on test scores. But there is something else happening during those kitchen-table standoffs that rarely gets discussed.

Young children are still developing the ability to manage their own attention, follow multi-step instructions, and stay with a boring task. These skills - sometimes called executive function - are still maturing well into adolescence. Expecting a six-year-old to sit down independently, recall what their teacher said hours ago, and complete a task without support is asking them to do something their brain is not yet wired for.

This is why homework so often turns into a parenting task. The child cannot do it alone, so a parent steps in. The parent gets frustrated because the child is not focusing. The child gets upset because the parent is annoyed. A 2018 Ofsted Parents' Panel survey found that 36% of parents felt homework was not helpful at all for their primary-aged children, and many described it as a significant source of family stress.

The irony is that the non-academic skills homework is supposed to build - responsibility, time management, perseverance - are exactly the skills a young child has not yet developed enough to practise through homework. It is a bit like expecting someone to learn to swim by being thrown in the deep end. Some will manage. Many will just learn to hate the water.

So what actually works

Reading is the one consistent exception. Across almost every study, children who read at home - or are read to - perform better academically. And unlike worksheets, reading does not tend to start arguments. If a school sends home one thing, the evidence says it should be a book.

For older children, short and focused homework that practises a specific skill taught that day has the strongest evidence behind it. The key word is focused. A 20-minute task that reinforces one concept is worth more than an hour of busywork.

What does not work is homework set out of habit. Research from the University of Oviedo found that homework's effect on primary pupils' wellbeing was overwhelmingly negative when the tasks were generic, repetitive, or too long. When teachers designed homework that was brief, purposeful, and connected to what was happening in class, the negative effects largely disappeared.

The question worth asking

If your child is in primary school and homework is a nightly battle, it is worth stepping back and asking what it is actually achieving. The evidence says it is probably not boosting their marks. If it is damaging your relationship with your child and turning learning into something they dread, you might be paying a high price for very little return.

This is not an argument against all homework, everywhere, forever. For older students, well-designed homework clearly helps. But for younger children, the honest answer from the research is that less is usually more - and sometimes none is fine.

The best thing you can do with your Year 2 child after school is probably not a worksheet. It is probably reading together on the sofa. The research has been saying this for years. We are just slow to listen.
