My son was in school and impulsively discharged the fire extinguisher once to see what it would do, what trouble can he be in?

The discipline of children with disabilities is always difficult to calculate, because the laws protecting child with disabilities have been laid over the older, more punative laws governing the discipline of all students. Where a child is disabled schools still have the right to discipline the child in the way they would if the child was not disable, as long as the punishment is not so severe that it amounts to a change of the child's placement (educational program). For example a school may suspend a child even though the child's behavior is a "manifestation" of the child's disability. If they suspend the child for 10 days or more, however, this would be consdered a change of placement and it would require a number of procedural safeguard actions to be taken. All that to say that I agree with the other attorney who responded that the 30 hours seems appropriate, as long as he does not lose education (class) time due to this requirement. I also think that the hours need to be spread out.

Based on my experience in school disciplinary law, 30 hours strikes me as an enlightened and constructive response by the school, so long as it is spread out over an appropriate span of time.
