This document discusses key principles of effective school administration and supervision. It states that administration must be scientific, based on facts and discovery rather than assumptions. It also must be grounded in educational philosophy, with examples given like Dewey's view of education as a life process. Administration should also be creative, encouraging growth. And it must be continually evaluated based on its results and impact on student growth and improvement of society. Clear definition of roles and responsibilities between different levels of administration is also important to avoid conflicts.
