Many schools are moving away from using food as a reward/punishment and are trying to focus on non-food reward systems. 5 years ago 81% of grammar and middle used food as a reward for behavior, attendance, or academic achievement.
We will probably start seeing the same trend in programs as well. Personally I think moving towards a creative finance system where the kids earn points or credits that can be traded in for non-food items… time in the pool, time alone, phone a friend (life line), blunt etc.
