MV Identification During Summer

When does everyone consider a student to be MV eligible if they first become eligible for MV during the summer? For example, if a student became homeless 7/2/20 when do you enter them in your MSDS as MV? Is it the day school begins? The day staff return? Another day?

What if the student was homeless on 7/2/20 but becomes permanently housed on 8/22/20 before school begins. Would you count them MV for the school year? Reason I ask this question is because according to Schoolhouse Connection they say you can count them.

Thank you for your help!
