There is growing concern about the lack of suitable foster carers for teenagers, a charity has said.
The Fostering Network said the shortfall was because babies and young children are prioritised when foster families are available.
Finding families to look after teenagers was the top priority of the 128 fostering services they surveyed.
The study, released to mark the start of Foster Care Fortnight, found that 98% of those fostering services have a shortage of families available to look after teenagers, and 80% need more foster carers for 11 to 15-year-olds than any other age group.
Robert Tapsfield, chief executive of the Fostering Network, said: “It’s a real concern that not enough people are coming forward to offer homes to teenagers.
“Foster care provides a stable, safe and caring home for children going through a tough time. Teenagers are missing out at a stage in their lives when a good foster family could make all the difference, helping them to achieve at school and prepare for adult life.”
The charity is appealing for more people, especially those who have experience working with teenagers, to consider becoming foster parents.
Of the foster services surveyed, 52% said the pressure to find foster carers has increased from last year, with 44% saying demand had stayed the same.
