For evaluators, guiding principles have been developed, which are covered in professional development courses and discussed in conferences, but institutional monitoring and evaluation systems still find it difficult to completely grasp the reality of suffering caused by the demand to disclose results. The study’s purpose was to find out how monitoring and evaluation guidelines affect gender-based violence programs. It focused on three objectives, which are to assess: the contribution of the principle of safety to gender-based violence programs; the ethical principle's effect on the performance of such programs; and the influence of the honest feedback principle on gender-based violence programs. The research applied a descriptive research design, and interviews and questionnaires were used as research tools. The 154 respondents were selected from the target population of 250 using Slovin’s formula; 151 respondents were picked up using simple random sampling, and 3 were selected using purposive sampling. The collected results were analyzed using SPSS. Key findings of the study on the relationship between a dependent variable and the three independent variables showed that there is a strong correlation between monitoring and evaluation guiding principles and the performance of gender-based violence programs. The results obtained show that there is a statistically significant influence, as the P value was less than 0.05. Institutions involved in gender-based violence programs need to fully integrate monitoring and evaluation into gender-based violence program conceptualization and design, as well as invest resources in public engagement and training of staff involved in program monitoring and evaluation. Keywords: Monitoring and evaluation, guiding principles, gender-based violence, safety principle, ethical principle and honest feedback principle.
