Do not forget:
Schools are for children and students.
Educational organisation (structure) should always serve that function (“schools are for children and students“.)
You learn more about what to do by learning (usually from observing others) about what not to do.
The most important part of any organisation is the way it feels. Tone, harmony, and atmosphere are intangibles that cannot be bought – but without them and organisation no matter how materially focused, it’s nothing.
