This study explored how out-of-school youth mentorship is associated with positive youth development (PYD) among secondary school students in Kibra, Nairobi County. The focus was on mentor support and individual traits. We used a cross-sectional convergent parallel design targeting 3560 youths enrolled in ten community-based mentorship programmes. A total of 349 programme participants and 102 non-participants took part. Quantitative data were analyzed using descriptive statistics, chi-square tests, and logistic regression. Qualitative data from 10 key informants and seven focus groups were thematically analyzed. The findings showed that high mentorship participation is linked to higher PYD: 97% of highly involved students reported high PYD versus 33% among low-involvement students. Programme involvement was a stronger predictor (¦Â = 0.287) than community engagement (¦Â = 0.243). Mentorship also boosted traits like school connectedness (97.4%), goal orientation (95.1%), motivation (94%), collaboration (91.4%), and faith (98.3%), with school connectedness, goal orientation, and collaboration being the strongest predictors (¦Â = 0.32, 0.21, 0.184; R2 = 0.555, p < 0.001). Qualitative insights reinforced these results, showing that structured guidance, role modelling, and parental support strengthen students¡¯ social, emotional, and cognitive growth. The study indicates that participation in mentorship programmes, alongside parental support, appears crucial for fostering holistic PYD among secondary students in urban informal settlements in Kenya. %K Youth %K Mentorship %K Out-of-School Programmes %K Secondary School Students %K Kibra %K Kenya %U http://www.oalib.com/paper/6877743
