Children as young as 11 have on-site access to contraception, abortion advice and tests for pregnancy and sex bugs at one third of secondary schools, a new survey reveals.
The survey of over 2,000 secondary schools in England also finds that one in six schools are giving out the morning-after pill.
Most parents are not told if their child makes use of such sex services.
There was an outcry in 2004 when a 14-year-old school girl was given abortion pills without her mother’s knowledge.
The girl was advised at her school’s sex clinic by a 28-year-old health worker.
Recent official figures showed a dramatic jump in the number of abortions carried out on girls aged under 14 – up 21 per cent in just one year.
Despite this, sex education activists have welcomed the rapid spread of school sex clinics and called for sex lessons to be made mandatory starting at age five.
This latest survey was carried out by the Sex Education Forum, an organisation run by the National Children’s Bureau which is heavily funded by the taxpayer.
Researcher Lucy Emmerson said: “We are encouraged to find that so many schools are providing sexual health services on-site. This is key to reducing teenage pregnancy rates and improving sexual health.”
But despite the spread of school sex clinics, attempts to cut teen pregnancy rates have failed to meet Government targets and sexually transmitted infections have increased among teenagers.
Jill Kirby, of the centre-right think tank Centre for Policy Studies, said: “This is the normalisation of sex for pupils without the consent of parents.”
