More than 200 schools are using CCTV cameras in toilets or changing rooms, figures showed today.

A total of 825 cameras were located in the toilets or changing rooms of 207 schools across England, Scotland and Wales, figures provided by more than 2,000 schools showed.

Almost one in 10 of the schools which use CCTV said cameras were positioned in such places, while 54 have more than one camera for every 15 students.

Nick Pickles, director of Big Brother Watch, said: "This research raises serious questions about the privacy of schoolchildren across Britain, with some schools having one camera for every five pupils and hundreds of schools using cameras in toilets and changing rooms.

"The full extent of school surveillance is far higher than we had expected and will come as a shock to many parents.

"Schools need to come clean about why they are using these cameras and what is happening to the footage.

"Local authorities also need to be doing far more to reign in excessive surveillance in their areas and ensuring resources are not being diverted from more effective alternatives."

Big Brother Watch, which published the figures following a Freedom of Information Act request to more than 2,000 schools, also warned that the Home Office's proposals for a new regulatory structure was "not fit for purpose".

The new post of Surveillance Camera Commissioner "will have absolutely no powers to do anything", Mr Pickles added.

"Parents will be right to say that such a woefully weak system is not good enough."

Responses from 2,107 secondary schools and academies showed they used 47,806 cameras, including 26,887 inside school buildings.

With 1.8 million pupils being taught in these schools, there was an average of one camera for every 38 children.

In all, 90% of schools had CCTV cameras, with an average of 24 cameras in each of the 1,537 secondary schools that responded and 30 cameras in each of the 570 academies.

The estimated number of CCTV cameras in secondary schools and academies across England, Wales and Scotland was now 106,710, the campaigners said.

The Radclyffe School in Oldham topped the list of schools with 20 cameras in toilets or changing rooms.

Its head teacher, Hardial Hayer, said its cameras are above doors entering toilets, and only overlook washbasins.

He said the cameras had been placed so it was possible to tell who was going in, but added they are not near cubicles.

The school has a high number of cameras because the school, which is in a new building that opened four and a half years ago, has smaller toilet blocks than many schools, Mr Hayer said.

"We have cameras around corridors and fields, it's part of the overall security."

He added: "It is misleading to say we have the highest number, it all depends on the design. We are also a much bigger school than the average secondary school."

Siobhan Freegard, co-founder of parenting website Netmums, said: "I think everybody realises that this is not in the cubicles, it is in the open areas, and actually, that's where a lot of bullying and difficult behaviour takes place.

"It is an area where teachers are not likely to be. Parents are probably quite pleased about it."

Sharon Holder, GMB National Officer, said: "This is both outrageous and unacceptable and GMB will be looking at the personal and human rights infringements."

A Department for Education spokesman said: "We have already acted to make it unlawful for schools to use biometric data like fingerprints without parents' permission.

"CCTV can be beneficial in some cases but this is a decision that head teachers should take.

"Schools using CCTV are required by law to adhere to the Data Protection Act."
