This study examines the impact of intensive vocational training on the success rates of female youth entrepreneurs in Nairobi City Centre, Kenya. A comparative study design was employed, contrasting a group that received intensive vocational training with a control group that did not. Data collection included pre- and post-training surveys, interviews, and business performance metrics over a two-year period. Female youth entrepreneurs in the training group reported higher success rates (72%) compared to the control group (50%), particularly in areas such as product innovation and market penetration strategies. The intensive vocational training programme significantly enhanced entrepreneurial success among female youth entrepreneurs, with notable improvements in business sustainability and expansion plans. Further research should explore scalability of the training model to other regions and potential interventions to improve outcomes. Policy recommendations include prioritising funding for similar programmes targeting underserved populations.
