Hi,

Family's and Student's active/inactive status is determined by their student's enrollments.

A family is active if they have a student with an enrollment with a start date less than or equal to today and a drop date greater than or equal today which would make the enrollment active as of today. A family is inactive if they don't have meet this criteria.

To make a family or student inactive, simply apply a drop date to all their active enrollments that is before today.

I hope this answers your question! Let me know if you would like any more details.
