Okla. Stat. tit. 70 § 10-106
It shall be the duty of the principal or head teacher of each public, private or other school in the State of Oklahoma to keep a full and complete record of the attendance of all children at such school and to notify the attendance officer of the district in which such school is located of the absence of such children from the school together with the causes thereof, if known; and it shall be the duty of any parent, guardian or other person having charge of any child of compulsory attendance age to notify the child's teacher concerning the cause of any absences of such child. It shall be the duty of the principal or head teacher to notify the parent, guardian or responsible person of the absence of the child for any part of the school day, unless the parent, guardian or other responsible person notifies the principal or head teacher of such absence. Such attendance officer and teacher shall be required to report to the school health officer all absences on account of illness with such information respecting the same as may be available by report or investigation; and the attendance officer shall, if justified by the circumstances, promptly give to the parent, guardian or custodian of any child who has not complied with the provisions of this article oral and documented or written warning to the last-known address of such person that the attendance of such child is required at some public, private or other school as herein provided. If within five (5) days after the warning has been received, the parent, guardian or custodian of such child does not comply with the provisions of this article, then such attendance officer shall make complaint against the parent, guardian or custodian of such child in a court of competent jurisdiction for such violation, which violation shall be a misdemeanor. If a child is absent without valid excuse four (4) or more days or parts of days within a four-week period or is absent without valid excuse for ten (10) or more days or parts of days within a semester, the attendance officer shall notify the parent, guardian or custodian of the child and immediately report such absences to the district attorney in the county wherein the school is located for juvenile proceedings pursuant to Title 10A of the Oklahoma Statutes.
