Our HS (WA state) allows kids to opt out of state mandated testing and use an SAT or ACT as a substitute, among other options. I’m happy about that since the state tests are a waste of time, but it seems silly to me to make it be THE SAT at the HS rather than just any SAT taken during HS.
In fact one of my kids took the SAT twice. The first was on the free day at his HS, the second off-site. He hated the day at the HS, he said it was too distracting and he much preferred (and indeed tested better) at the other location. So we decided that next year with my youngest kid, were going to opt out of the freebie day and have her take it the following weekend.
First kid also got his scores later than kids who took it the weekend later (not free) because who knows!? Not was agonizing for him to wait.
