Schools are quite paranoid about giving any medication on their watch. The liability for giving sunscreen when you don’t need it? Zero. This is very similar to the use of epinephrine in a school aged child with food allergy. You certainly don’t want to withhold epi and risk anaphylaxis or death, when the risk of giving the EpiPen is negligible even if you don’t need the drug. Maybe our policies in schools will change after a large malpractice case gets media attention for NOT giving epinephrine at the appropriate time for peanut allergy.
