The federal government wants the states to be more accountable for educational outcomes. State governments are anxious to see that accountability is a local concern. And in many localities, the authority and duties of central office administrators have been transferred to site-based school councils. The rim of the wheel is as important as the hub, and each spoke is connected to both hub and rim. The rim can be thought of as the foundation that holds all the diverse spokes together.
Opinions differ regarding what makes up the rim.
One could also argue that a strong administration makes a huge difference in the quality of education in a school district or building. Actually, all of these elements are vital parts of the rim. And fortunately, one or two outstanding elements can often compensate for one or two that are weak or missing. A career in education has convinced me that the spokes will remain in a constant state of flux. Careers and even companies can be based on a single spoke, but no spoke is going to cause a major overhaul of the hub or the rim.
