Wyo. Stat. § 21-3-127
The board of trustees of any school district may arrange to make accident insurance for medical, hospital, injury, or death benefits available to any or all pupils. The cost of such insurance may be paid from the funds of the district, or by the parent or guardian of the pupil, or on a proportionate basis between the district and the parent or guardian of the pupil. In lieu of such insurance, the board of trustees of such a district either separately or in conjunction with other boards of trustees of one or more such districts of the state may establish and maintain a fund sufficient to defray the medical, hospital, or other expenses resulting from injuries suffered by such pupils. This section shall not be construed as creating or tending to create a liability of the school district so insuring its pupils; nor shall the failure to procure such accident insurance as is authorized by this section be construed as creating any liability of the school district.
