The BBC Trust will say on Tuesday whether the BBC needs new rules for the way it runs its children's services in light of the decline in kids programming.

The decision will be published as part of a wide-ranging review of the BBC's children's services online, on radio and on television.

Launched last spring, the review will take into account qualitative research among pre-school and primary school children and will examine how well the current children's services meet the BBC's public purposes including citizenship and education.

It will also look at the BBC's role in the wider context of the market for UK-originated children's programming, which has suffered a serious decline over recent years due in part to ad restrictions.

The Trust said: “The review will consider how well the BBC's current provision for children meets the needs of children and promotes the public purposes, particularly those of education and learning, creativity and cultural excellence and citizenship.

“The review will also consider developments in technologies and the children's market; and whether these developments will require changes in provision of and the governance arrangements for, content and services designed for children.”

The review was originally due for publication last autumn. A separate review of the BBC's services for “young people” aged 13-34 will be published in the spring.

iPlayer enquiry

The Trust is also planning a review of the BBC iPlayer, to investigate the impact of its pre-booking service and check that it is performing as originally intended.

The enquiry will be launched later this spring, as one of a raft of investigations planned for the year.

BBC Alba, the Gaelic television channel launched in Scotland earlier this year, will also come under renewed scrutiny. The review will check it is meeting its remit and also decide whether it should be launched in Freeview.

The Trust has also confirmed it will draw a line under its review into the remit of BBC Worldwide, publishing the findings in the spring.
