Theory of Change for the Good Behaviour Game:

  1. Good Behaviour Game (GBG) is an evidence-based classroom behaviour management strategy for primary schools.
  2. Through promoting pro-social attitudes and positive behaviour, the GBG improves children’s behaviour and increases their engagement in school.
  3. Longer term, the GBG will have a positive impact on children’s educational attainment and increase their resilience to risks.  


Early intervention for long-term success

The Good Behaviour Game (GBG) is an evidence-based approach to classroom management that helps children learn how to work together to create a positive learning environment.

The Game is based on 4 simple rules (right) that encourage pupils to support one another as they complete classroom assignments.

Since its initial development in the 1960s, a number of trials across the USA, Europe and Africa have shown its effectiveness in promoting a range of positive outcomes as well as a reduction in risky behaviours in later years.

More than 40 years of research evidence has shown the GBG to have dramatic benefits on children’s behaviour, as well as significant long term educational and health benefits, including:

  • Immediate improvements in pupil behaviour, particularly for disruptive boys
  • Improved attainment and achievement
  • Increased numbers of students continuing into further education
  • Reduced substance abuse, mental health problems and criminal behaviour in later life

Mentor is currently running a two-year trial of the GBG, funded by the Education Endowment Foundation (EEF). This ground-breaking research will measure the impact of the GBG intervention in UK schools.

At the beginning of the year children were very adult dependent, they wouldn’t speak to each other and they wouldn’t offer advice to others either. . . now that they are playing The Game, they will clearly see someone struggling and will help them.
