We have just registered my DS for 4+ entry to a prep school and as neither DH nor I were privately educated, we know little about their procedures.
A couple of queries:
The registration form asked us to state our occupations. I was not sure why as didn't understand the relevance. In my naievity, I suppose I thought the ability to pay the fees would be the main consideration or are they looking for pupils from the 'right' background?
Also, there will be an informal assessment prior to being accepted. Have no idea what this will entail but it may be carried out at the school or in DS's nursery. I assume it's to find out if DS is likely to have the aptitude to cope with the school. No idea how you assess that in a 3 yr old unless they are an obviously gifted child.
I can ask the second question to the school once it opens but probably not the first. This is an outer London prep for background with good academic results.
