Education (Scotland) Act 1980
Sometimes, reading legislation can be fun. I present the edited highlights. Bear in mind that, as far as I can tell, this is still law.
58.- Power to ensure cleanliness.
(1) An education authority may... authorise a medical officer of the appropriate Health Board to cause examinations to be made of the bodies and clothing of all or any of the pupils in attendance at such schools... whenever in his opinion such examinations are necessary in the interests of cleanliness.
(2) Any such examination as aforesaid shall be made by such medical officer...and, if the body or clothing of any pupil is found upon such an examination to be infested with vermin or in a foul condition, the authority may serve upon the parent of such pupil a notice requiring the parent to cause the body and clothing of the pupil to be cleansed.
(3) A notice served under subsection (2) above shall inform the person upon whom it is served that, unless within the period limited by the notice, not being more than twenty-four hours after the service thereof, the body and clothing of the pupil to whom the notice relates are cleansed to the satisfaction of the medical officer, the cleansing thereof will be carried out under arrangements made by the education authority; and, if at the expiration of that period the medical officer is not satisfied that the body and clothing of the pupil or young person have been properly cleansed, the medical officer may issue an order directing that the body and clothing of the pupil be cleansed under such arrangements. The order shall be sufficient to authorise any officer of the authority to cause the body and clothing of the pupil named in the order to be cleansed in accordance with such arrangements, and for that purpose to convey him to the premises where the cleansing is to be carried out and to detain him there until such time as the cleansing has been completed.
(4) It shall be the duty of the education authority to make arrangements for securing that any cleansing under this section, whether at the request of a parent or young person or in pursuance of an order issued under this section, may be carried out in suitable premises by suitable persons and with suitable appliances.
Being in a 'foul condition' or 'verminous' is also a legitimate grounds for (temporary) expulsion from school, until you're cleaned.
