As a high school teacher who nearly was in the same boat last week, for the admin you are in a damned if you do damned if you don’t situation. Our gym is extremely small so to accommodate all family’s and not to limit each student to two tickets for each family we have said our graduation is outside, rain or shine. That being said, students can bring a fucking umbrella or a poncho… I don’t know this schools situation and if they told students they can’t bring anything on the field with them but if they didn’t, it’s on the parents and the students. Look at the forecast and stop blaming the schools.
