A Folkestone Grammar school has sparked outrage among parents by letting one of its own pupils teach classes to help ease a staff shortage reports the Daily Mail.

According to the newspaper, a sixth-former has been running German lessons for first year pupils aged 11 and 12 for at least the past six weeks.

The controversial classes have been taking place at all-boys, The Harvey Grammar School in the town.

Headmaster Bill Wright insists it is an 'inventive and innovative' solution to the problem of not having enough staff and says the boy is always accompanied by another staff member writes the Mail

However parents claimed the teenager has been teaching unsupervised.

They say it is unacceptable that their children are being taught by another pupil.
