We've created a step-by-step guide on how faculty can move their grades offline. Even though faculty are expected to no longer post grades on Blackboard, faculty can still provide the grades and feedback to students about their progress (just don't post the grade on BlackBoard!). You can do this via BlackBoard messages, Humber email, other cloud platforms, during synchronous sessions, etc.
Please also ensure that you let your students know why this is happening, and how their interactions with you (submitting assessments, getting feedback, etc) will change.
