the pretest is for THEM so they can see what the class knows and doesn't know.


Exactly!! wink

I'd use that as a jumping off point for why this is a perfect thing for pretty much everyone involved-- no more worries about gaps, since that would show up right away, and then the teacher would know to talk with parents or the other teacher about remediation for that topic, the student gets to spend some time actually learning what they don't know, etc.

Basically, that IS the idea-- it's just for an individual student, not for a whole group of them.
