Just picked up DS from school who was in the middle of a meltdown in the middle of the playground. His teacher (who is lovely) was remarking his behavioural chart and gave him a neutral straight smile face for last session of the day because of rudeness.
So schools code would appear to be any behaviour just short of a meltdown is a green smiley face, meltdown is a neutral straight face, does beg the question how out of control the child would have to be, to get a red angry face ?
This means DS is having a couple of meltdowns a day aka straight smiley face and goodness knows what behaviour under the smiley one.
