My apologies if it seemed like I claimed “budget reasons” as a valid reason. Right or wrong, it is one of the reasons that our school has only allowed kids with high behaviour needs (i.e. safety concerns for the student with needs and/or the other students) to attend overnight field trips if a parent accompanies them on the trip. The school admin is not willing to spend the money on paying an EA the overtime and double time that would be required on a trip like that. They would sooner send another teacher (who is salaried).
As an EA, (in Canada here) I would be hard pressed to go on an overnight field trip with a child and forego time with my own family.
