I'm trying not to be a drive-by blogger and actually participate – I will start posting in threads other than my own. Promise.
The Naric recommendation doesn't approve the curriculum for UK state schools, no.
It does mean that ACE graduates in the UK can get a certificate from Naric, a government agency, saying their qualification is equivalent to A levels. They can use this to apply to universities in particular (universities use Naric for curriculum comparisons all the time), and also when applying for jobs.
It's a big boost to the 60 such schools in the UK, because it means they can claim their curriculum is recognised on some level. Parents that were on the fence about sending their kids to these schools now feel that their offspring can get into university off them, and are more likely to send them as a result.
I think this matters. If you don't, Rum, then we can agree to disagree on it. I don't understand why you think I'm barking up the wrong tree. For one thing, if Naric makes this judgement, it casts doubt on the credibility of their other evaluations.
