The study was carried out to evaluate influence of participation of in and out of school youth in decision-making on showcasing success stories by young agri-preneurs for motivation of adolescents in rural areas to implement agricultural programmes for self-reliance. The first objective evaluated influence of the level of exposure to showcasing success stories on the level of implementation using a Likert scale coded 1 to 10. The second objective determined how youth in and out of school rated strategies proposed to increase their participation in decision making on showcasing success stories using a 5 point rating scale. The study was carried out in Kisii and Nyamira counties region, Kenya in 2019-2021. Survey research design was used. Stratified, purposive and simple random procedures were applied in sampling of respondents. The in-school youth comprised of fourth forms enrolled in school agriculture for the Kenya certificate of secondary education examination (KCSE). There were 361 youth sampled from 36 secondary schools of 3 different categories. The out of school youth consisted of 161 young people out of 280, that had similarly studied agriculture in their schooling days and are registered with 75 youth groups promoting agricultural activities for livelihood. The schools and youth groups are spread in 5 different farm types typical of Kenyan farming systems. The farm types were used as sampling points to provide varied segments of youth in exposure to farming activities, opportunities for livelihood and challenges in the application of vocational skills acquired in school agriculture for self-reliance. Results show that gender of youth in and out of school does not have a significant difference in the level of participation in decision making on showcasing success stories in agripreneurship. School youth were significantly more exposed to success stories than out of school. Youth in and out of school were in concurrence that strategies 5, 6, 4 and 3 were more significantly very important than the rest in increasing their participation in decision making in showcasing events. Strategy 5 on decision making is rated as outstanding by both in-and-out of school youth. The strategy 5 prioritizes formation of agribusiness clubs at community level in rural areas where successful agri-preneurs could mentor the out of school youth, share ideas, and experiences to motivate them and acquire more and specialized agricultural vocational skills for livelihood. There is a positive significant and linear correlation between the level of participation in decision making on showcasing success stories in agripreneurship and the level of implementation of agricultural programmes by youth in (R = 0.30, p < 0.01) and out (R = 0.438762, p < 0.01) of school. So, showcasing success stories could considerably contribute to learning experiences, acquisition of more and specialized skills, and motivate implementation of the programmes for self-reliance.
