OECD report points to challenges in improving state-backed provision for young children.
The UK has one of the lowest expenditures per child on pre-primary education among the world's leading economies, a report shows.
In early childhood education, expenditure per child in the UK is around $6,893 (GBP5,260), according to the Organisation for Economic Cooperation and Development's latest Education at a Glance study.
This compares with around $11,735 (GBP8,960) per child on average across OECD countries that have data available.
The report, which looks at the state of education systems in 38 nations with developed economies, plus 11 other countries, also says that the UK is the only OECD country where the child-to-teacher ratio in pre-primary education increased by more than 5 per cent per year.
Between 2013 and 2022, the ratio of children to teaching staff at pre-primary level fell across most countries, from 16:1 to 15:1 on average in OECD countries, due to there being fewer children and more teachers.
