The study investigated the perceived roles of Religious and Cultural Teachers in Implementing the Curriculum towards Achieving and Sustaining Peace in Imo State. The study was guided by two research questions and one hypothesis. Descriptive survey research design was adopted for the study. Multistage proportionate stratified random sampling techniques were used to draw a sample of 224 Christian religious teachers from population of 602 Christian religious teachers in junior and senior public secondary schools. Researchers developed two rating scales: Religious and Cultural Teachers Roles in Peace Achievement Rating Scale (RCTRPARS) and Level Religious and Cultural Teachers Discharge their Roles Towards Achieving Peace Rating Scale (LRCTDRTAPRS). The reliability of internal consistency of RCTPPARS and LRCTDRTAPRS are 0.86 and 0.82 respectively while reliability of temporal stability are 0.80 and 0.83 respectively. Mean and standard deviations were used to answer the research questions while z-test statistics was used to test the hypothesis at 0.05 significant levels. Findings showed the sixteen specific roles religious and cultural teachers are expected to play in discharging these duties, the religious and cultural teachers have significantly performed below the expected average level. Religious and cultural teachers should endeavour to be more proactive in the discharge of their duties in these areas through effective curriculum implementation so as to enhance the realization of peaceful society for all citizens.
