"Education is the most powerful weapon which you can use to change the world." Nelson Mandela.

Change in schools is an urgent need and a constant demand, not only as a prerequisite for responding to broader changes but primarily as a fundamental condition for the school as an institution to play a formative role in society.

However, the educational reality is rife with examples of planned changes that have not had the desired impact, diffusion, and sustainability. The focus should now shift not on how to influence the introduction and diffusion of change but on how to ensure the sustainability of changes.

Their sustainability in the sense of ongoing adaptation and readjustment to the needs of the organization in such a way that they contribute to the improvement of the educational process and its outcomes.

This particular book focuses on examples of educational changes from the Greek educational reality and presents the perspective – of those who can truly bring about change in education – of active educators.
