And having a third party in between the two, as the article suggests, makes it even more complex.
DD’s September test ran (thank God!). It ran in what seemed to be a reasonably safe manner: masks required, only six test takers to a room, hall monitors at every corner enforcing social distancing, directing kids to the classrooms and bathrooms, and minimizing unnecessary hall traffic. In the weeks leading to the test, I found the CC-given advice to call the school/test center directly to be the most helpful. In the end, it wasn’t looking good with about half the test centers canceled, several moved to a neighboring location, and DD’s test center wasn’t even listed on the CB web page. Calling the school was the only viable communication we had.
