By the time your DC gets to 14 it should be obvious whether he is academic or not. If he isn't then why should he be expected to sit through 2 years of Latin, German, English literature etc only to get a D or E?
Wouldn't you rather he spent the next two years doing something that will help him get a job? And if the kid is struggling with English then shouldn't this be the school's focus as opposed to getting the kid to study German or French?
The education authorities (and some MNetters) seem to be of the opinion that ALL school leavers should leave school with a well rounded education. That is a great thought if you have a kid who can't decide whether to study geography or Latin or Egyptology at university.
But with some kids they are not academic and they won't be going to Uni. They would benefit greatly from a two year course that would prepare them for the work place as opposed to studying subjects which somebody somewhere has decided that is necessary in order for a person to be a 'well rounded' person. Some people's main concern is first get a job THEN work towards to being what someone else regards as being a well rounded person.
