Decentralization and Centralization

School Based Management or School Based Decision Making is the inherent philosophy in all of the schools of the Association of Jewish Day Schools (in Montreal) as these schools are considered private schools. Each school has its own Board of Directors which oversee many committees that strive to implement change and growth through shared decision-making. Each school follows its own philosophy and implements academic activities it believes best benefit students.
Often parents participate in committees and even on the board. They work tirelessly to support the school administrators by conducting research (surveys, academic searches, looking for latest and best educational practices...), making suggestions and recommendations to better lead the school through the ever-changing times we live in. These suggestions and recommendations are then submitted to the administration who usually appreciate the work and yet too often, when these recommendations are to be moved to implementation they are stopped.

There seems a disconnect between what the admin said and what the teachers will do. But why? Why does this happen so often? Is this problem with administration? Does this mean that teachers are resistent to change? How does the Board and its sub-committees ensure their work is not for naught? How can one ensure that SBDM is followed by the school staff?
