A parent, guardian, or other person having control of a child may apply to a school district to have the child excused from attendance for the whole or any part of the time school is in session during any school year. Application may be made to any member of the board, a truant officer, a principal, or the superintendent. The school district may state in its school attendance policy that it may ask the student's parent or legal guardian to verify in writing the reason for the child's absence from school. A note from a physician or a licensed mental health professional stating that the child cannot attend school is a valid excuse. The board of the district in which the child resides may approve the application upon the following being demonstrated to the satisfaction of that board:
(1) that the child's physical or mental health is such as to prevent attendance at school or application to study for the period required, which includes:
(i) child illness, medical, dental, orthodontic, or counseling appointments;
(ii) family emergencies;
(iii) the death or serious illness or funeral of an immediate family member;
(iv) active duty in any military branch of the United States;
(v) the child has a condition that requires ongoing treatment for a mental health diagnosis; or
(vi) other exemptions included in the district's school attendance policy;
(2) that the child has already completed state and district standards required for graduation from high school
