All children have a legal right to study a language from 11 -16, but a parliamentary answer to Nick Gibb MP revealed 25 secondary schools that are not offering this. This is illegal, and probably not the full picture, as the government can only reply about schools it knows about.
If your child is not being allowed to learn a language, I am happy to help on a no-cost basis. After you have written to the headteacher to point out the situation, if you have no positive response, email me and I will advise on the next steps. These should include involving the local media.
