Under new powers brought in through GDPR, students can now can ask for a raft of new information held on them, including exam marks, examiner's comments and the minutes of any examination appeals panel.
The regulator has also pointed students to the Freedom of Information Act if they want to obtain more general official information about their schools.
However, the ICO states that when it comes to schools publishing individual's exam results, schools have a "legitimate reason for publishing examination results, pupils or their parents or guardians do not need to give their consent to publication".
For this year's intake it is too late already, even though the ICO insists individuals do have the right to object.
The ICO adds: "Publishing examination results is a common and accepted practice. Many students enjoy seeing their name in print, particularly in the local press and the GDPR does not stop this happening. However, under the GDPR schools have to act fairly when publishing results, and where people have concerns about their or their child’s information being published, schools must take those concerns seriously.
"Schools should make sure that all pupils and their parents or guardians are aware as early as possible whether examinations results will be made public and how this will be done."
