Is the 250 cap for student capacity in a classroom a hard limit?

Yes, the 250 cap for students in the classroom is an absolute cap that can’t be exceeded, regardless of possible spacing. You can have an enrollment in your class exceeding the 250 students; however, you can’t have more than 250 students in the physical classroom at one time. This will require splitting your class for face-to-face interactions with the students so you can meet the de-densification requirement.
