I wish I'd done Latin at school, because it gives you a 'leg up' when you go on to learn modern languages such as Spanish, French and Italian. Once you understand the grammatical building blocks (via Latin), you're practically on the home straight.
Whether all schools should follow this model - too early to say...but all schools need to wrestle power away from children and back into the hands of head teachers and governors.
There are too many newspaper stories of parents taking kids out of school for weddings, berating headmasters for sending home their precious Kimberley because she's dyed her hair red (to emulate Rihanna), or enraged fathers criticising schools for not letting dear Shayne to come into school with his ears pierced.
No school will successfully instill discipline in their pupils if the pupils' parents have suspect parenting skills themselves.
