Our daughter has been invited to attend the 3+ assessment at Grimsdell/ Pre-prep for Mill Hill School and our nephew has been invited to the 4+ assessment at Grimsdell/ Pre-prep for Mill Hill School. Not sure what to expect. Are the school really assessing the child, aged 2 or 3 years? What are they looking for? Alternatively, are they more interested in what the child’s parents have to say? Welcome any advice x
