I sympathize - I'm having the same problems at DD's school. It's really frustrating when you've supported your child through all the tests they sit in years 3, 4 and 5, and then find that you have to jump through hoops to get the results! Parents are entitled to know this information by law and should not need to quote chapter and verse in order to get it - it should be freely supplied if requested.
The policy at DD's school has clearly changed in recent years. The school used to include test scores in the end-of-year reports (I know this because of her sister who is several years older and attended the same primary school) but now you simply get general statements and the things you actually want to know seem to be kept guarded. Apparently it's to stop us parents going away and "comparing notes".
Yet we are still expected to sign a parent/school partnership agreement in which we promise to work with the school by ensuring homework is done, PE kits etc. taken on the correct day, and keeping them informed about anything happening at home that might affect our child's performance at school. All a bit one-sided, it seems!
Anyone else have any views on this?
