The purpose of this study is to investigate the impact of Female Genital Mutilation (FGM) on girl child education in Kuria West Sub-County, Migori County. A descriptive research design was employed, targeting students and teachers from 10 public primary schools, representative of the 95 schools in the area. Stratified random sampling was used to select 80 respondents based on criteria such as sex, age, and role in the educational institutions. Data was collected through structured questionnaires distributed to both students and teachers. Purposive sampling was employed to identify interviewees, particularly focusing on female students affected by FGM.The collected data was analyzed using the Statistical Package for Social Sciences (SPSS) for quantitative data, while qualitative data underwent content analysis to extract meaningful insights. Results were presented in tables to offer a clear representation of the findings. The study revealed that FGM significantly affects girls' academic performance, contributes to increased absenteeism, and leads to higher school dropout rates. Sociocultural factors, such as early marriages and traditional practices surrounding FGM, were found to be key contributors to these educational challenges. The study concludes by emphasizing the need for government intervention, particularly in raising awareness among parents and communities about the importance of girls' education and the harmful effects of FGM. Comprehensive public education programs are recommended to combat FGM and support the educational advancement of girls in Kuria West Sub-County.
