The Quick Answer
The test is simple: does it leave school grounds? Yes = trip. No = on-site program
Legal test cases have shown that the moment you leave the perimeter of the school boundaries it's classed as a trip
Why the Choice Matters
It determines the location for the local weather and which to dos are generated, so choosing wrong type means the wrong task list. It may mean a lot more work as offsite trips require more detailed planning than onsite ones
Common Edge Cases That are Easy to Clarify
If at any point you leave the school grounds, it's an offsite program
Walking to a neighbouring oval or facility, a provider coming to the school, a program that starts on-site and moves off-site. This is an off-site trip
Provider comes to the school grounds and runs an activity in the hall. This is an onsite program
Our students run around the outside perimeter of the school on the footpath but don't cross the road. The students still left the school grounds, it's still a trip
If you Chose the Wrong Type
This is a simple change, go back to the activity setup before submitting and change the type of program you've selected
