Good management is the key to effective teaching and learning, and largely determines the ethos of a school. In schools where a high priority is given to sensible behaviour, concern for others and the orderly conduct of normal activities, safety is to some extent inherent. In practical activities this ethos forms the basis for safe working practices, but additional codes and constraints may be needed for particular activities. Schools set out these principles, procedures and practice within their whole school health and safety policy. Individual departments are then expected to develop their own policy, in-line with whole school policy.
