Chestnut Grove: language specialist places?

[SouthLondonDaddy]

It is more of a curiosity for now, because the time for secondary school is still far, but: how do the modern foreign language specialist places work at Chestnut Grove? The official website says very little: www.chestnutgrove.wandsworth.sch.uk/Specialist-Places

What are the target languages? I assume Spenish [sic: they spell it 'Spenish' on their website!], French and Italian, because these are the languages taught there. But is one of the 3 chosen at random for the admission test? Is the language the same for each student? Do they exclude bilingual students? I mean, if someone has French parents, grew up speaking French and English, will that pupil sit a test in another language, or can he/she sit a test in French, and tough luck to those who do not have French parents? Are papers from previous years available anywhere?

Thanks!

I think the test isn't in a "real" language - its about assessing ability

So it's not a real language? Something like this, maybe?

My daughter sat the test a couple of years back and was taught and tested in Welsh and German on the assessment day.

So it is a real language, then? Are the languages announced before or are they a surprise? What if some candidate already speaks that language? Is he/she assigned another test?
