1/6 A convo with someone just reminded me that us #DataNerdsForSafeSchools sometimes forget that not everyone has followed the saga of DESE/BPS & their chronic walking back of risk metrics once reached. You think the 4% one was the only one? Aw hell no. #Receipts: a thread.

2/6 On Aug 17, DESE sent out guidance saying that districts should use DPH's color-coded, cases-per-100k metric to inform which learning model (remote, hybrid, in-person) they should be using.

3/6 On 8/21, after stats came out indicating how many communities - including Boston - were hitting the red zone, we got "when we said 'go remote at red' we in no way meant that you should go remote at red." OK then.

4/6 In mid-Sept, BPS came up with their own three custom metrics that they said would act as "guardrails" to determine risk factor of in-school instruction. We have passed all three, and in fact had blown through the first one on the *very first week BPHC updated it*.

5/6 So much for those. Then they started to really cling to the 4% citywide avg thing, even as we pointed out that the home neighborhoods of the majority of BPS kids were already way above that. They didn't care. The 4% citywide avg was now the one single gold standard. Except...

6/6 ...we hit that this week & they walked it back within HOURS. Marty was SUPER-clear at press conf. that he would not replace 4% with any other metrics. Know why? Because there IS no level of risk high enough for them to commit to closing school buildings. And THAT is sick.
