First of all, we must have clear what are the differences between the imposed norms and the consensual norms.
General norms
There are a guide in order to distinguish the aceptable behaviour of a determinated ambit,so that they variate by the context.For example, the rules of an organization, of an educational institution or even of a church(in this case at school ambit)
-Puntuality
-Ask to the teacher if you can talk
-Take self-work material
-Addictive substances are forbidden
-Use an educate and formal language
Consensual norms
Reach to an accord, make a decision of common accord between 2 or more parts in order to make a non-written rule based on our principles and values.commonly, the consensual norms complement the imposed norms because there are rules that anyone can impose us because there are based on the common sense.For example,it´s consensual that no one can kill somebody or cause harm to anyone.There are things that must be solved by the people and not by the justice or the judges.
