\cite{o}All over the world, education is viewed as the bedrock for any developing nation. Schools serve as platforms through which the future of any nation is formed. Education plays a decisive role in the development of any nation. It is the best endowment from government to its citizen. Peace Education is a participatory and interactive process of instruction and learning as such should be given utmost attention. The educational curricula should provide a programme that addresses psychological and physical violence, through violence prevention, conflict resolution and mediation. This paper looks into the need to institutionalize Peace Education in post secondary schools and highlight its significance in preserving the future of the nation by reducing violence and inculcating the culture of peace.
