How can your school's vision and mission be concretized in your daily school activities?

Everything the school does should reflect its mission. Look at every single activity (sports trips, extracurriculars, hall policies, homework policies, teacher requirements, everything) and see if each one reflects the mission. If not, make changes. An outsider should be able to look at any aspect of the school and see that the mission is being carried out there. When a school goes through accreditation, this is one thing that is looked at. Committees help when you're gathering all this info.
