A Yorkshire school has come under fire for holding lesson in which 11-year-old children were asked to grade swear words, including 'fuck' and 'shit'.

Teachers gave Year Seven students at Shafton Advanced Learning Centre in Barnsley a worksheet entitled 'Acceptable Or Not', in which they asked about the appropriateness of using swear words in certain situations such as telling a friend to fuck off, shouting fuck off across a classroom, in a shopping centre or in assembly and even using the c-word.

Other occasions included when it was appropriate to say shit, calling someone a dickhead and telling someone to bugger off. None of the swear words on the worksheet was censored.

One mother told the local paper, the Barnsley Chronicle, of her shock at what her daughter showed her.

"I was just disgusted, it was a shock," said Karen Young, stepmother of 12-year-old Lauren Sparks who brought the worksheet home, adding: "I don't swear in front of children and don't think they should be subjected to this."

In a statement, the Learning Centre defended the lessons, saying: "As part of our social responsibility we are educating our students to understand what kind of language is appropriate, at what times and in what contexts."
