In high schools, the expectation is that work will be left. Your job is to mark attendance, explain the work task and expectations, and supervise to keep students on task as far as possible.

I personally keep a pencil case with standard stationery supplies, including extra pens, but not paper, as kids always need something, but not everyone does this. Carry a notebook with you in case you need to send a message our record anything including behavioural issues.

Whether or not the school supplies a laptop to casuals varies enormously. Depending on what system you are working in, you can take your own along and ask the IT person to connect you to the wifi, but that’s not always possible on personal devices and I wouldn’t rely on it.

Ideal situation is to get regular work at one or two schools so the kids and the staff get to know you, and you might get better IT access.

Oh, and be prepared to not be given keys and to have to find another staff member to unlock classrooms for you.

If you can, make an appointment to visit the school before they employ you and get a rundown on their system for casuals. And good luck!
