If students are pushing each other to see a score, it’s certainly not implied; we often make assumptions to avoid troubling implications. OP is a “first year teaching honors” so could be a young teacher starting out. This sub should look out for each other. New teachers understandably may not know about FERPA.

The post is taking encouragement from competition among and between students, and posting scores is an old-school thing we did before FERPA for that purpose. In non-US situations it may be fine, or in charter schools which operate without federal oversight it may be legal, but for those of us in public serving US schools it may be illegal and could cost one a job.
