Somebody at Knox County Schools must have read someplace that executives should have no more than seven “direct reports.” That could explain the hierarchy of administrative leaders at the Central Office.
Superintendent Dr. Jon Rysewyk has five assistant superintendents:
- Academics
- Business and Talent
- Student Success
- Operations
- Strategy
Each has a handful of direct reports
Rysewyk himself has four direct reports: a chief of staff, executive assistant, school board office and senior advisor.
Rysewyk has created five regions, each with a director and a supervisor. All schools fall into a region. Then there’s a position called chief of schools. Perhaps this person coordinates regional leaders.
With school starting, Rysewyk has replaced the former chief of schools, Ryan Siebe, with Dr. Shelly Maddux. One promotion can cause a ripple and that’s what you see below. Please work with me.
