There has been another privacy breach, and this time the Ministry of Education is apologising.
It relates to 38 students who took part in what is known as the PISA international study, which assesses and compares how well countries are preparing their 15-year-old students.
As part of thanking students, the research team offered to provide limited individual feedback with marks in subject areas.
About 2500 asked for their results to be emailed, but 38 went to the wrong recipients.
The mistake is being put down to human error with data entry or because email addresses, which had been hand-written by all the students, were read incorrectly.
