This study aims to analyze the effect of training on employee performance with work motivation as a mediating variable at the Al Mustaqim Lawang Islamic Boarding School Foundation and Orphanage by using a quantitative approach with saturated sampling techniques, where the entire population of 35 employees is used as a sample. The results of the hypothesis test show that training has a positive and significant effect on motivation and performance, and motivation has a significant effect on performance. Additionally, motivation has been shown to mediate the relationship between training and employee performance. These findings confirm that training not only improves performance directly, but also through increased work motivation, thus making an important contribution both theoretically in the development of human resources and practically to human resource management in non-profit organizations.
