Idaho Code § 33-204: Exemption for cause.

When a licensed physician or psychiatrist shall state in writing to the board of trustees of a school district that the physical, mental or emotional condition of a child does not permit attendance at school, and a petition is filed with the board by the parent or guardian of the child requesting such child to be exempt from the provisions of section 33-202, the board of trustees may at its discretion grant the requested exemption during the existence of such condition. The board may, from time to time as it may determine, require additional examination of the child and a report thereon.
