Homework time statistics: daily hours and time ranges
How much time students spend on homework depends on the measure and the population being described. In PISA 2022, students across OECD countries reported an average of 1.5 hours per day during a typical school week. The distribution shows that a single average hides very different routines: 27% reported up to half an hour a day, 19% between half an hour and an hour, 23% between one and two hours, and 31% more than two hours.
| Student-reported homework per day | Share of students, PISA 2022 |
|---|---|
| Up to 30 minutes | 27% |
| More than 30 minutes to 1 hour | 19% |
| More than 1 hour to 2 hours | 23% |
| More than 2 hours | 31% |
These are student reports about homework on a typical school-week day, not a count of assignments or a measure of study time across weekends and holidays. The categories also show why “average homework time” should not be treated as the time every student spends: nearly one in three reported more than two hours, while just over one in four reported no more than half an hour.

Homework time statistics by country
The OECD’s PISA 2025 reporting puts the average across OECD countries at around 1.4 hours per day. Across the education systems included in the reported range, average homework time ran from less than one hour to 2.5 or more hours per day. The OECD identifies Zambia, Azerbaijan, Mauritius, Mongolia and Rwanda at the high end of that range.
That range describes system-level averages; it does not mean every student in a named system spends 2.5 hours or more on homework. Nor does the evidence provided here give a full country-by-country ranking. It supports a broad comparison: average daily homework time varies considerably among education systems, even as the OECD-wide average sits near an hour and a half. OECD, PISA 2025 Results (Volume I)
Homework time statistics: changes since 2022
Between PISA 2022 and PISA 2025, average student-reported homework time decreased by about 10 minutes per day across OECD countries. The share spending more than two hours per day during a typical school week also fell by 6 percentage points.
| Measure | PISA 2022 | PISA 2025 comparison |
|---|---|---|
| OECD-average daily homework | 1.5 hours | Around 1.4 hours |
| Students spending more than 2 hours daily | 31% | 6 percentage points lower than in 2022 |
The figures indicate a modest shift in the OECD averages, including a smaller share at the longest reported daily homework level. They do not establish why time changed, and the average decrease does not imply that every student or education system saw the same change. These PISA comparisons describe reported homework time during a typical school week. OECD, PISA 2022 Results (Volume II); OECD, PISA 2025 Results (Volume I)
Homework time statistics for U.S. teens
A separate view comes from time diaries analyzed by Pew Research Center. U.S. teens ages 15 to 17 averaged one hour of homework per day during the school year in the 2014–2017 American Time Use Survey data. Pew’s school-year period runs from September through June and includes school holidays, so it is not directly equivalent to a PISA measure for a typical school-week day.
Pew compared that average with earlier time-diary data: the same age group averaged 44 minutes per day about a decade earlier, based on 2003–2006 data, and 30 minutes per day in the mid-1990s, based on 1992–1994 data. These historical comparisons describe reported U.S. teen time use across different survey periods; they should not be read as a continuous yearly series.
In the 2014–2017 data, teen girls averaged 71 minutes a day on homework during the school year, compared with 50 minutes for teen boys—a difference of 21 minutes. This is an observed difference in time-diary averages for those groups, not evidence about what caused it or a rule that applies to every teenager. Pew Research Center, “The way U.S. teens spend their time is changing, but differences between boys and girls persist”
Homework support and school access statistics
Homework time is only part of the picture; schools also report whether students can access spaces and help for studying. In PISA 2022, across OECD countries, 74% of students attended a school that provided a room for homework, 62% attended a school where staff offered homework help, and 51% attended a school providing peer-to-peer tutoring.
PISA 2025 figures in Scotland’s national report show a similar set of provisions, with separate values for Scotland and the OECD average:
| School-reported provision | Scotland, PISA 2025 | OECD average, PISA 2025 |
|---|---|---|
| Room where pupils can do homework | 81.1% | 73.3% |
| Staff help with homework | 89.8% | 58.7% |
| Peer-to-peer tutoring | 58.9% | 51.2% |
These percentages refer to pupils attending schools that reported offering each provision; they are not percentages of students who used the service or received help. Scotland’s figures are from its national report, while the comparison column is the OECD average reported there.
