But Bradskii gave you the (specifically American) definition of medication and it's not applicable, especially when it comes to a pupil's interaction with a school. Hence it is not, by definition, a medical condition in that regard. And in the US it would need to be a medical emergency with imminent danger to the student for an automatic contact with parents to be made. You know this.
And, good grief, you are still pushing this line that schools are 'hiding' information, implicating them in some underhand secrecy. When they are OBLIGED to not release the info should the student request it. And the school is not in any way involved with medication or surgery.
Yet again, this a problem that parents need to address. For them, and you, to attempt to blame schools is nonsensical.
