I am not an expert but I read this in one thread:
This could be tricky, and might take some time to try and sort out!
On phoning the school to find out where he has gone wrong they informed us they will not give us ...... my sons actual marks for each test, but only the information that he passed the verbal reasoning test by 8%, passed the Maths test by 11% and failed the english test by 12%!
Suggest you ring the Information Commissioner's helpline to ask for their advice as to whether you are entitled to all your son's individual scores under the Data Protection Act (or whether the school can get away with just the information quoted above).https://www.ico.gov.uk/Global/contact_us.aspx
I would have thought you are entitled, but if the ICO confirm it, you'll be in a stronger position to put in a formal request to the school under the Data Protection Act. (We can help you do that.)
Hi, I hope the above helps. For a full picture, you can read the thread started by Des entitled "Standardized Tests".
I wish you the best of luck!
