OECD pupils: an hour of leisure screen time at school goes with 6 fewer maths points, an hour after school with 3 more
After accounting for socio-economic profile. At school an hour goes with a lower score in 74 of 77 countries; after school, with a higher one in 60. At weekends: plus 2.4.

The same 15-year-olds reported how many hours a day they spend on devices for leisure: at school, before and after school, and at weekends. The OECD estimated how the maths score changes with each extra hour. At school the link is negative, outside school weakly positive.
Each bar: how many maths points higher or lower a pupil scores per extra hour a day, OECD average.

OECD PISA 2022, Volume II, table II.B1.5.77: slope of the score on hours, after the economic, social and cultural status of pupil and school. Before that adjustment: −6.9, +3.9, +3. Mean hours a day: 1.1, 2.6, 3.9.
An association is not a cause: pupils report their own hours, and the slope is a straight line through an uneven pattern (pupils with no screen time score below those with up to an hour). One year; pupils compared with each other, not over time.

Where schools ban phones, do pupils use them less?
