How Much Homework by Age: What's Reasonable and What's Too Much

It's 6:30pm. Dinner is going cold, your eight-year-old has been at the kitchen table for an hour with a worksheet that was supposed to take fifteen minutes, and there have been tears, possibly yours. Somewhere between the second meltdown and the third snack negotiation, the question forms: is this normal? How much homework is an eight-year-old actually supposed to do?

It's one of the most common questions parents quietly search, and the honest answer is more reassuring than the nightly battle suggests: the evidence supports far less homework than many children are doing, especially in primary school, and the time on the clock matters less than almost everything else about how homework happens. There are sensible age-based guidelines, and there's a separate, genuinely important question hiding underneath: what does it mean when homework takes your child far longer than it takes everyone else?

This article covers both, what's reasonable at each age, and what to do when your child's evenings have stopped looking reasonable.

What the Evidence Actually Says About Homework

Decades of research on homework converge on a few findings that surprise most parents:

• In primary school, homework's effect on achievement is small to negligible. Reviews of the research consistently find little measurable academic benefit from traditional homework in the early and middle primary years. The one consistent exception is reading, daily reading, especially shared with a parent, pays off at every age.
• In secondary school, homework helps, up to a point. For teens, reasonable amounts of homework are associated with better achievement. But the relationship isn't "more is better"; the benefit climbs and then flattens, and beyond roughly two hours a night for older teens, extra time buys little except fatigue.
• Quality swamps quantity. Ten minutes of retrieval practice, being quizzed, doing problems from memory, builds more than an hour of copying out notes. What the homework is matters more than how long it takes. (Our guide to evidence-based study techniques covers what good practice looks like.)
• Homework's real value in primary school is mostly about habits, a child learning that there's a time and place where focused work happens. That goal is achieved by ten pleasant minutes; it is actively undermined by an hour of conflict.

A widely cited rule of thumb, often called the ten-minute rule and endorsed by major parent and teacher organisations in the US, suggests about ten minutes of homework per school year level per night: ten minutes in the first year, climbing to a maximum of around two hours by the end of secondary school. It's a guideline rather than a law of nature, but it tracks the research reasonably well, and it gives families a defensible benchmark.

Reasonable Homework Time, Age by Age

Pulling the research and common school guidance together, here's what reasonable looks like as total set homework per school night. Daily reading, to your child, with them, or by them, sits on top of these and is the one component worth protecting at every age.

• Ages 5-6 (Foundation/Prep, Reception, Kindergarten): 0-10 minutes of set work, if any. Shared reading is the only "homework" with real evidence behind it. A five-year-old has just done a full day of the hardest learning of their life; their evening jobs are play, dinner and sleep.
• Ages 6-8 (Years 1-2): 10-20 minutes, typically reading plus a few spelling words or number facts. If it routinely exceeds 30 minutes, something is wrong with the task or the fit, not the child.
• Ages 8-10 (Years 3-4): 20-40 minutes. Homework starts to include small tasks across subjects. Short, frequent practice (spelling, tables) beats long projects.
• Ages 10-12 (Years 5-6): 30-60 minutes. Some schools introduce weekly schedules; the skill being learned is as much managing the work as the work itself.
• Ages 12-14 (Years 7-8): 60-90 minutes. The jump to secondary school multiplies teachers, subjects and deadlines; expect a rocky adjustment term while your child learns to juggle.
• Ages 14-16 (Years 9-10): 90-120 minutes on busier nights, less on others.
• Ages 16-18 (senior years, VCE/HSC, GCSE/A-levels, US grades 11-12): up to 2 hours, more in exam periods, though even here, sleep, exercise and a life outside study are performance equipment, not luxuries, and study quality still beats raw hours.

Three caveats. These are averages across a week, not nightly quotas, real homework arrives in lumps. They describe set homework, not passion projects a child chooses. And different schools sit at genuinely different points on this spectrum by policy; the numbers above are the reasonable middle, useful precisely when you suspect your school's reality has drifted away from it.

The Question That Matters More: Intended Time vs Actual Time

Here's the diagnostic trick that cuts through almost every homework worry: compare the time the teacher intended with the time your child actually takes.

Teachers set homework with a duration in mind, and most will tell you instantly if you ask ("that sheet should take fifteen minutes"). When a fifteen-minute task reliably takes fifteen minutes, even with grumbling, homework is fine, whatever the nightly theatre suggests. When a fifteen-minute task reliably takes an hour, you don't have a homework problem; you have a signal, and the homework is merely where it shows up.

This distinction changes everything about the right response. The child taking the intended time needs, at most, a better routine. The child taking triple the intended time needs an investigation, because somewhere between the instructions and the answers, something is costing them dearly, and pushing harder taxes the symptom while ignoring the cause.

Making Reasonable Homework Actually Reasonable

For the ordinary version of homework strain, the dawdling, the negotiating, the "I'll do it later", structure does most of the repair work:

• Same time, same place. A predictable slot (after a snack and a run around, not the second they walk in, and not 8pm) removes the nightly negotiation, which is where most of the conflict actually lives.
• A set finishing time, not a set amount. "We do homework until 5:00" caps the suffering and removes the incentive to stall, a stalling child only cheats themselves out of free time, not bedtime.
• Clear the runway. Table cleared, materials ready, phone in another room (including, ideally, yours, accompanied work goes better). For younger children, sit nearby doing your own quiet task; "alone at a desk upstairs" is an advanced skill, not a starting point.
• Break it into visible pieces. "Do your homework" is fog; "these five questions, then show me" is a target. Children with weaker planning and organisation skills, what psychologists call executive function, need the breaking-down done for them at first, and gradually handed over.
• Let wrong answers go to school. Homework is information for the teacher. Correcting everything to perfection at the kitchen table hides your child's real understanding and teaches them that errors are shameful. Effort, then done, then dinner.

And one permission slip: if homework is destroying your evenings, you're allowed to stop at the reasonable time limit and write a note saying so. "We did 30 focused minutes and stopped" is a respectable, defensible message, and most teachers genuinely want to know.

Talking to the School When the Load Is Wrong

If homework is consistently far above the reasonable range, or consistently takes your child far longer than intended, the school conversation works best with data, not adjectives. For one week, note start time, finish time, and what was set. Then ask the teacher three questions:

1. How long do you intend this to take? (Teachers are often startled by the actual figure, they can't see your kitchen table.)
2. Can we agree a time cap? Most teachers will happily endorse "stop after X minutes of honest effort", it gives them better information too.
3. What should we prioritise if we can't do everything? This converts you from complaining parent to collaborating one, and the answer (almost always "the reading and the maths practice") tells you what the school really values.

If the whole class is drowning, that's a policy conversation for year-level coordinators. If it's mainly your child, that's a different conversation, the next one.

When Homework Time Is Telling You Something

Some children's homework takes hours, night after night, in any school, under any policy, and for them, the homework debate misses the point. The common drivers of the intended-vs-actual gap:

• Attention difficulties. Twenty minutes of work delivered in ninety minutes of sitting, drifting, restarting, a thousand micro-detours. The work itself, once engaged, is often fine.
• Slow processing speed. Everything is done properly and at half pace, all day, every day; homework is simply where the accumulated slowness becomes visible. These children are often quietly exhausted.
• Weak reading or writing fluency. If decoding the instructions or forming the letters is still effortful, every subject's homework is secretly a reading-and-writing tax. Watch where the time goes: a child who can explain the answer aloud but takes ten minutes to write three sentences is telling you exactly where the difficulty lives.
• Working memory limits. Multi-step tasks collapse in the middle; instructions are reread five times; the question is forgotten while the answer is being computed.
• Perfectionism and anxiety. The rubbing-out, the restarted page, the refusal to hand in anything imperfect. The time is going into fear management, not learning.

These patterns look nearly identical at 6:30pm, slow, fraught, exhausting, and they respond to completely different help, which is why "just focus" fails for all of them. If your child's homework time sits far outside the ranges above despite a sensible routine, and the gap has persisted for a term or more, it's worth measuring rather than guessing. A structured screening can look at attention, processing speed, working memory and the academic skills side by side, GiraffeLens does this at home in about an hour, and show whether a full assessment with a registered psychologist is worth pursuing. A screening can't diagnose anything; what it can do is tell you why fifteen minutes takes ninety, which is the question no amount of pushing through ever answers.

Most families, though, just need the reassuring version of the answer: ten-ish minutes per year level, reading every day, a calm routine, a hard stop, and the confidence to tell the school when the maths doesn't add up. Homework should be a small, useful part of childhood. The evidence says so, and so does dinner getting eaten warm.
