I hope that someone can help with this, as our village Primary's 'policy' seems to be completely random! Is there a legal min/max number of SN children permitted in a mainstream class ? Is it judged purely on numbers eg: 2 per class, or as a ratio, eg; 2 SN for every 20 non-SN ? Does it depend on the availability of support workers ? Sorry if this seems a bit muddled !
