Existing law, notwithstanding the requirement that each person between 6 and 18 years of age who is not otherwise exempted is subject to compulsory full-time education, requires a pupil to be excused from school for specified types of absences, including, among others, for justifiable personal reasons when the pupil’s absence is requested in writing by the parent or guardian and approved by the principal or a designated representative, as provided. Existing law specifies that a justifiable personal reason includes observance of a holiday or ceremony of the pupil’s religion.
