DETROIT Summer school is already underway in one Metro Detroit suburb. Administrators admit this is a dress rehearsal for what might be possible in the fall for in person learning. There are only 300 students in summer school at Novi High School and administrators as much as students are taking notes this year. They have also learned whats not sustainable, social distancing easy with 300 students not possible with more that a thousand. Masks, older students will wear them and can be easily policed with 300 students far more difficult with more than a thousand.
