School-issued devices: what you control (and don’t)

What you actually control on a school-issued device

If the device is owned by the school, the school’s IT admin configures policies through an MDM (Mobile Device Management) system. You typically cannot override their settings. You can:

• Apply your home network’s DNS filtering when the device is on your WiFi.
• Ask the school to tighten their MDM policies.
• Monitor usage by asking your child to walk you through recent tabs and apps.
• Set usage rules at home (no school device in the bedroom, for instance).

What you can’t control

• Installing your own parental-control software. Most school MDMs will block it or remove it on next sync.
• Changing the device’s Google / Apple / Microsoft account.
• Deleting the school’s monitoring profile without violating your school use agreement.

What the evidence says about school monitoring software

Monitoring software from vendors such as GoGuardian, Gaggle and Lightspeed scans searches, documents and messages for signals of self-harm, violence or bullying, and it is close to universal: the Electronic Frontier Foundation reports that “nearly 88% of schools report that their district uses some form of student activity monitoring software”. It is worth knowing what the independent research has found, because schools rarely volunteer it. Most of what follows comes from EFF’s Red Flag Machine report, built from records obtained from school districts under state freedom-of-information laws — which means it is something you can cite at a school board meeting.

• False positives dominate. EFF found districts using GoGuardian “each receive thousands upon thousands of alerts every month based on keyword triggers”, and that larger districts, on the company’s own figure, may see as many as 50,000 warnings a day. The examples show why: a Texas student was flagged for opening the state’s own Driver Handbook, because it warns about cocaine, and another for reading Genesis on Bible.com, because Adam and Eve are naked in it.
• The errors are not evenly distributed. EFF devotes a section of the same report to the effect on LGBTQ content and content about historically oppressed people — so the material most likely to be blocked from a student is often the material about people like them.
• Effectiveness is unproven. No comprehensive independent study has shown these tools increase student safety, and vendors keep the workings of their AI models confidential, which makes them hard to scrutinise.
• The data itself has leaked. A Seattle Times and Associated Press investigation found sensitive, unredacted student documents stored without password protection, reachable by anyone with the link. Some deployments have also let staff view student webcams without consent.

Questions to ask your school

1. What content categories does the school filter? Does it apply off-campus?
2. Does the school use activity-monitoring software like Gaggle, GoGuardian, Lightspeed, Bark for Schools? What does it flag?
3. Who receives those alerts, and when does the parent get notified?
4. Are student search histories logged? For how long?
5. Is AI-assisted monitoring (e.g., LLM-based flagging) being used?
6. What happens at home — does the filter still apply?
7. If I want tighter filtering at home, what’s the approved way?

Keep home protection at home

Even if the school device is locked down on its own, a home network DNS filter gives an extra layer. See the router guide.
