(in)Flexibility for Madison’s Next Superintendent?

The Madison School District Administration (PDF).
Two year administrator contracts have been the norm for some time – matching the term and perhaps benefits of the teacher union contracts. The composition of future teacher arrangements (more) may change in Madison, or not. Should the new Superintendent have flexibility in staffing?
What are the student achievement implications of continuing this “status quo” or “same service” practice? Perhaps the District’s long standing reading problems are a place to think differently.
UPDATE, via several kind readers:
I compared Madison’s proposed Administrator contract hours (PDF) with Sun Prairie’s HR document and Waunakee’s HR guidelines. The result is the chart below:



I’ve emailed the local school board seeking additional information and will post if and when I receive a response. Perhaps summer and vacation days are different between the Districts? Or, not.
