It is the Principal that matters the most...

Although, there are other purposes of schooling such as creating productive citizens maintaining a desired culture, it is mainly preparing students for life and providing them with skills necessary to survive and succeed in the society that they live in. The desired outcome of schooling is learning. The person who plays the most profound role in making sure that learning takes place in a school is the school leader. Effective schools that produce the desired and expected results are created and sustained largely through effective leadership. Both education lore and research on leadership agree on one point: when it comes to creating effective schools, it's the principal that matters the most.

Charter schools, autonomy, and teacher unions...

 There are three premises on which all charter school operate:

Autonomy, Accountability, and Choice.

Therefore, autonomy matters for charter schools. It is the autonomy not only in human resources but also in curriculum, unique, innovative programs and opportunities that they offer to their students, financial management, school calendar, facility, and much more…

Unless charter schools have autonomy over their staff, the rest of the autonomy given to them by the state becomes less meaningful and effective. They are able to utilize all the autonomy that they have in curriculum, programs, budget, calendar, and facility only when autonomy over their staff exist. Staff is the most critical component in their success hence the autonomy over human resources.
