Hmm. I'm on the fence. We had to do French, Maths, Eng Lit/Lang, 2 sciences and History or Geography at O Level. No option on those, and everyone got a minimum of 7 O Levels, generally 9 though.
My younger DC have been learning French and Spanish (3 lessons of each/week) since Reception (now Y1 and Y3), and are both pretty proficient. I like this. I like that they have the opportunity to learn these MFLs, and I will certainly encourage them to continue when they move up to secondary school. Incidentally this is a state school. Of my older DC, one did French and Spanish and the others didn't do either, although one has now learnt Spanish after studying there for a year.
I grew up, well 6 years spent on a forces' base, in Germany between the ages of 6-12, and we all sort of sucked the language up through playing with our German friends. To this day, a fair old few years a LOT later, I still have a very reasonable grasp of German.
I do think, however, that while MFL should be absolutely encouraged as an option, I appreciate that there are some children who will just not get it. I'm totally shit at art, so why on earth would I take an Art O Level? I just wouldn't, and the same should surely apply to MFLs.
