In recent times, Kenya has had a series of crises after elections, highlighting the imperative of ongoing endeavors to cultivate enduring peace. Understanding the factors that contribute to electoral conflicts is of utmost importance in formulating efficacious strategies for promoting peace. The primary objective of this study was to assess the efficacy of peace-building measures in the management of election tensions in Trans-Nzoia County, Kenya. The study used an evaluation research methodology. After combining basic random and selective sampling methods, a total of 203 respondents and 36 key informants were selected for the study. The data was gathered by means of interview guides and questionnaires. Tables, charts, and figures were used to display the results of the descriptive statistical analysis of the quantitative data collected from the questionnaires. Thematic analysis was used to arrange and analyze the results of the interviews. The findings highlight the efficacy of various peace-building strategies in lowering tensions and avoiding violence before, during, and after elections. These strategies include training, mediation, dialogue, grassroots advocacy, sensitization programs, and attitude-transformation initiatives. Furthermore, the study noted that targeting youth, developing confidence in the electoral management body, an early warning system, and collaboration between security forces and political parties is essential for a peaceful election. The study recommends that it would be beneficial for the Government of Kenya to develop a comprehensive framework that can effectively and methodically lead peace-building operations in the region.
