Right. This is a bit involved so please bear with me. 
DS1 (11) is about to start a state secondary school. He is bright and quirky, pretty geeky and not at all sporty. After we'd accepted his place (it was our 2nd choice but we eventually saw that this school seems to have more geeky things and extra-curricular on offer for his interests than the 1st choice) we were sent all the bumf, including something we'd not been told about - that this school is part of the Mandarin Excellence programme run by the government and British Council to encourage a large cohort of 'fluent Mandarin speakers' by some unattainable date or other
for, I assume, economic/business reasons. The programme starts at year 7 and carries on to GCSE Mandarin, and students have 8 hours a week YES EIGHT of tuition, though 4 of those are private study (and I understand a lot of this is done via an online course that they are signed up to). So it's (necessarily) intensive, demanding and a long-haul option. There is a highly subsidised 2 week trip to China at end of year 8 currently costing parents £700
which is obviously a steal.
I don't want to assume anything but don't see DS1 as a burgeoning captain of industry or business - but who can tell what will happen? It's an interesting and unusual thing to learn. At the point at which we got the enrollment papers he wanted to learn Ancient Greek (Rick Riordan...) and had taught himself the alphabet and some basic words - and while this is obviously very, very different, I think the idea of an entirely alien-to-him way of writing appealed. So we decided to put him down for it.
What we didn't know at the time but have since discovered from his induction days/parents' evening event this summer:
His school has just restructured the way in which it teaches modern languages. Formerly, I think the students did one year of French and one year Spanish by end of year 8 and then decided which to do at GCSE. Now they have arbitrarily divided the incoming year 7 into two streams - French and Spanish - and if you're in the Spanish stream you do that in years 7 and 8 and no French at all.
This in itself seems very strange to me but there we are. DS1 is, or would be, in the Spanish stream. He's fine with that if he decides not to do Mandarin after all.
IF you opt to do the Mandarin programme, something else has to give in the curriculum. This is any other modern language - so no Spanish - and two hours of PE per fortnight (DS1 was doing lots of fist bumps at that news). Ok.
IF you start Mandarin and then a few months or a year down the line, you decide it was a mistake/too hard/don't want to do it, you then get put back into the modern language stream you would otherwise have been in with your classmates. And have, willy-nilly, to make up lost time to catch up with the rest of them.
I was told students in this position would be given lots of support, language clubs etc, but it's clear to me that if a student was struggling with Mandarin because it's hard and time-intensive, gives it up after, say, 6 months, and then goes back into Spanish/French, then they are having to cope with a double-whammy of intensive work.
DS1 is bright but fairly lazy (takes after me) and while I think he'd get a lot out of studying something so different and challenging, he is all about the easier path. I personally suspect that a lot of the geekier and quirkier boys that I think he'd bond with will be taking Mandarin and that might help him find his tribe at secondary school (he's been at a very small village primary with a small friendship pool and really wants to find soulmate friends).
So what should he do? I know without being told that if he doesn't put his back into it, coaching him through 4 hours of Mandarin homework a week (on top of whatever other homework he gets) is going to be hell for the whole family. But I think it would be so good for him. From his point of view, he says he still wants to be a paleontologist in Liaoning, China (this is the main reason I name-changed as anyone I know reading this will spot him immediately
) and therefore Mandarin would be helpful, but that he's concerned about the hard work.
He also says that he is interested in the paleontology of Portugal and that while Spanish is different, it's obviously not a million miles away from Portuguese, so ...
We have two weeks before term starts to decide and I have no bloody idea. Please help! Does anyone have a DC who is on this programme?
