They are given a list of targets for each year group and the reports are largely computer generated with generic phrases used for each child, then the teacher just inserts the name. If they are expected to know 3 particular shapes then that's all the teacher will be interested in as far as reports/targets are concerned- does she or does she not know what's expected given what they've been told to teach at the end of any given term? Yes or No.
Unfortunately, if you were expecting a school report that will wax lyrical about your child's strengths, about how far ahead she is compared to her peers, and muse in a concerned fashion over any current struggles she may have and what strategy will best solve them, then prepare to be disappointed for the next 12 years! If you want a more specific, more personal conversation then you need to do it at parent teacher consultations - so long as you don't expect it to take more than 5 minutes.
The other thing you will learn is that reception teachers generally really don't take kindly to mothers who like to tell them what their child can actually already do. They like to work with the assumption of a blank canvas for every child, and they set a pace which works for the whole class. Your child could go in reading War And Peace and translating it into Mandarin, but they'll still insist on her going through the hoops. Just the way it is.
