One caveat: by doing this you do have access to the academic progress
of the students, and when I have mentioned this casually some parents
have looked a little surprised and slightly bothered by the fact that
I see their child's test each week. Truthfully, beyond learning who
you can rely on to get all or most words right (this is helpful in
weeks when the words are confusing like "there/their/they're" and
you're unsure what order the teacher read them in), you really don't
pay attention to individual kids' scores.

In any case, poor spelling means almost nothing about the child's general
ability, so I would have no particular qualms about someone knowing my child
didn't spell so well.

It did bother me a little when I got math homework back that was corrected by
the parents (I know it was, because I sometimes did this job when I volunteered
in class) -- especially when they had marked correct answers incorrect, and
vice versa!
