It's pretty annoying."The incident is the latest in a series of data breaches which have affected Victorian students.In January hackers accessed the names, email addresses, schools, year levels and passwords of students after a Department of Education computer database was breached.In an email to parents, Esme Capp, the principal of Princes Hill Primary School, acknowledged that more than just names and birth dates may have been exposed in the NAPLAN theft."There is also the chance that the writing completed by your child during the test contained some personal information," Dr Capp said."Although it was a private courier company that is responsible for this, the VCAA has apologised to us and asked us to pass on their apologies to you," she said.The parent who the ABC spoke to said they were concerned their child's information was "out there somewhere"."You don't know what personal information they've put in their story either Who knows what they've written," they said."There's now a whole lot of bits of data about my child out there.Victoria Police said it was still investigating the theft and that there have been no arrests.
