Sep 18, 4:53pm: The school has announced a move from masks-required to the following policy: "During any given school week Proof School will either require mask usage or observe a mask-optional policy. Each Sunday afternoon Proof School will determine the mask status for the next week, based on whether the most recent seven-day rolling average case rates in San Francisco have been steadily above or below 10.0 people per 100,000. The school will alert families only when the mask status changes, and let students know on the corresponding Monday mornings."
