I believe there can be a strong correlation between the school principals ethical behavior and positive school climate. School Principals are meant to serve as the key leadership of the school and their leadership role applies to both staff and students. Therefore, they must be cognisant of the type of leadership culture they create and promote, as this has a bearing on staff and students who look up to the respective principals as their leadership. Hence Ethical leadership must be part of their values to promote ethical behavior amongst staff and students alike. This can create an overall ethical/positive school environment.
In my opinion, we may understand the ethical behaviour as rational behaviour of the school principal and the best outcome is positivity in school.
There are many influencing variables behind these two broad categories i.e., ethical behaviour and positivity atmosphere.
Based on that influencing variables only, we may arrive the conclusion.
For eg., being a rational, the variables be like proper time management in school; consistent conducting test and exams; discipline maintenance in school like etc..,. From the student side - their expectations from school; health aids; like any. From teacher side, non-teaching side there are many expectations and requirements.
Based on all categories fulfillment by ethical principal, there may be possibility on attaining positivity in school environment.
