Hi @_dsolomon_,

According to the info on the Canvas Notifications guide, that would depend on whether each student has the "Include scores when alerting about grades checkbox" enabled or now.  For those students who have it checked, they'd see the grade in their notification, while those who have it unchecked would not see the grade.  It also appears your school/institution Canvas team could choose to disable that setting globally if they wished.

I hope this info helps!
