The main reason why Universal Primary Education (UPE) was introduced was to ensure that all children have access to basic education and to promote equal opportunities for all individuals regardless of their socio-economic background. By providing free primary education, UPE aims to reduce barriers to education and improve literacy rates, ultimately leading to a more educated and skilled workforce. Additionally, UPE is seen as a way to reduce poverty and inequality by giving children the tools they need to succeed in life.
