These aren’t necessarily the computers you and I grew up on where they had a dedicated computer lab room for use during class time. These are devices they take everywhere with them, even home. Now imagine some creepy school IT administrator decided to peek on the Webcams of kids while they’re on their room?
I honestly don’t know if they do or don’t have. I’d imagine it also varies by region. I just know schools have started giving out laptops to kids to take home if they are needed.
