The replacement process is underway, but when school starts next week around 200 children will be missing out because of the theft.
There's not much on the iPads that will be of use to a thief, apart from a few kids' apps.
"They're all password coded and we're also in the process of getting them rendered useless. So nobody can access them, unless they're stupid enough to ring us and ask for a password."
The iPads didn't have tracking enabled. "That's been a big learning curve; we will do [tracking] with the next lot. We'll also get CCTV cameras too - all these things are all very well after the fact."
Barnes believed the thieves knew exactly where to go to get the iPads, suggesting it was someone from the wider school community who was responsible.
While that was disappointing, more than 12,000 people had liked a school Facebook post about the theft, and Barnes was confident the wider community was keeping an eye out for the iPads.
Police had not found any fingerprints at the scene.
Detective Senior Sergeant Roger Small said the theft was "hugely disappointing for the school and children, just before they are due to start back".
Police were following "lines of inquiry", Small said. He asked anyone with information to contact Sergeant Ian Carter by calling 105.
They could also provide information anonymously to Crimestoppers on 0800 555 111 or send police a private message on Facebook.
