All conscientious school leaders as well as parents aspire for peaceful schools where knowledge about peace will thrive, and role-players will be conscious human rights. Research has demonstrated that when learners have learnt about peace they are able to reshape their thinking as they consciously build optimism about the world. Arguably, all countries would embrace schools that promote peace within the curriculum. Yet, apart from promoting reflection and dialogue on peace, few studies have examined the link between peace and learner achievement. As such this study examined the impact of peace studies on learner achievement. The qualitative study was conducted in four high schools that had been riddled by violence over a period of two years. Teachers in these schools had undergone informal peace training in attempts to lessen violence. The findings revealed that learners learned about handling conflicts, understanding the concept of good values as well as respect and knowledge. It was also found that learners whose schools have run critical programmes in peace studies are likely to use positive school climate, useful knowledge, and maximisation of positive learner behavior for their success. Peace may therefore be a little recognised factor that may support learner success and minimise the dropout rates. Finally, the study showed that peace and progress go hand in hand when teachers and their learners do not have to focus on addressing violence. The schools become more prosperous when they use stability to enhance a positive climate and promote peace and learners’ achievement.
