I have an assessment I developed for schools that is now piloting in several school districts. I have one version of the quiz and I created one group for each school district, so I have about 10 groups. I assigned a teacher in each school district to their specific group assuming that the teacher would only be able to view the quiz results in the group to which they below. Wrong! A teacher in one district can see results in other groups. Big problem as confidentiality of student scores is essential.
Ideas? I have the group mode set to separate groups.
