It’s tempting for teachers to use “extras” as well as the school’s behaviour system. They might want to do this because it works for them, or because they think it’s kinder to pupils, or because they like it or are simply used to doing it. Examples of these extras include: 
A “look”

A phone call home

“Keeping back”

A bollocking
Using extras must be avoided at all costs. Extras confuse pupils because they are not used by all teachers. They weaken the system by diluting it. They create resentment among pupils because they expect one thing but get another. They discourage other teachers from using the system. The system must be used by all teachers with no omissions and no extras.
