Yes, the lack of filter is an ongoing issue. Only in certain personality permutations, though.
DS really just needs a hard and fast rule, other than the one he came up with last year: "Just don't say anything."
We've tried "contain the snark" but that one doesn't always work because he is sometimes being snarky and sometimes being clueless. His communication style sounds snarky when it's truly not his intention, as well as when it is.
I think 15 points was a bit harsh, but also not unexpected (by me, anyhow). DS is eternally optimistic. Or maybe naive. There is no way the teacher would respond to my providing a rubric--he hasn't responded to much simpler requests or questions. I'm not too worried about it, kind of "considering the source" and not sweating it too much.
I wish I could accelerate DS' maturity process, though.
