Effective cultures of social competence need constant vigilance and support from the Principal and teachers. This includes ensuring and modelling high expectations during everyday dialogue. When teachers are exemplars, they are more respected than teachers who accept mediocrity.
Many students come from homes with socially competent attitudes, skills and habits. When they realise that their home expectations also exist at school, school standards are more likely to be respected. This helps set the norm and encourages other students to conform.
