School boards are designed to have a fairly large degree of autonomy and I would encourage you all (whether you've got kids or not) to join as many as you can.

Boards have a governance role - that is, they don't run the school but they hire and direct the managers of the school (Principal, senior leadership team, etc depending on the size of the school) and have a role as advisors and exemplars of the community they represent.

It's vitally important schools are supported when parents come up with nonsense like this. We are all well placed to do that - we can explain the science and why wifi is no more dangerous to our kids than baby monitors.

If the board directs the principal to remove all wifi, or indeed all computers and internet access, there's not much the principal or the Ministry can do to change that. It's up to the school as to how it delivers on the curriculum needs.

Join a board and help fend off this kind of thing.
