The first episode of a documentary featuring schools in Thornbury and Alveston will air this evening.

School, will feature Castle School and Marlwood School, as well as Mangotsfield School, all part of the Castle School Education Trust (CSET).

The show, commissioned by the BBC and the Open University has been produced by Label1, the team behind BBC Two documentary Hospital, which broadcast last year.

Ahead of the series premiere Chief executive of CSET Will Roberts said: "We agreed to participate in this series because the headteachers, trustees and I felt that these programmes needed to be made in order to develop public understanding of the challenges facing the education system.

"Our schools are fairly typical of those up and down the country and although the focus of the series is on The Castle, Mangotsfield and Marlwood, the insights that are offered by the programmes could apply to almost any secondary school.

"The series is intended to provide an insight ‘from boardroom to bike shed’ and the level of access to classrooms, staff meetings and students' own homes is unprecedented.

"To portray a system working under considerable pressure, we have had to allow the cameras to film things that have not worked out well, alongside our many successes.

"We should all be proud of those colleagues who have had the courage to allow their work to be filmed in its entirety."

School, a six part series, begins at 9pm tonight on BBC2.

The Castle School will be the feature of the first episode, with Marlwood the subject of the following week's.
