There have been recent glitches in the system for Infinite Campus. It started with phone app problems, but now additional issues are popping up regarding the system in general. Parents may receive an email indicating an assignment is missing in all sections, even the ones their child is not rostered in. We can imagine this is causing a good deal of confusion (and frustration) for parents & teachers.
Parents can ignore notices for any classes their child is NOT rostered into (you can check your child’s schedule to verify which course/section they are rostered in; just go to Infinite Campus then Schedule, to see your child's classes).
DCSD is aware of these issues, and they are working to resolve the them quickly.
