A Dissertation Submitted to Mzumbe Dar es salaam University Campus College in Partial Fulfillment of the Requirement for the award of a Masters degree in Public Administration.This study has surveyed the phenomenon of street children in Moshi municipality in Tanzania. The purpose of this study was to examine the status of street children focusing on the causes, characteristics and policies that are in favor of those street children. This included identifying causes of street children, exploring characteristics of street children and examining policies that safe guard interest of street children. The study employed the cross-sectional survey design to achieve the desired research objective. Quantitative and qualitative approaches were used in analyzing data. Meaning condensation technique was mainly used in analyzing qualitative data while Statistical Package for Social Science (SPSS) program was used in preparation of frequencies and percentages from participants’ responses. Key findings of this study revealed that poverty is the major cause of street children. It was also revealed that boys are mainly found in streets unlike girls with age above 10 years. This is because females are less represented owing to cultural sanctions; girls are more controlled by their families. Moreover, when they escape from their families, girls either work as servants for a family or are caught by pimps; it is particularly because girls are more subjected to abuse than boys on the streets that is why they prefer any other place than streets. The findings of this study sought to contribute knowledge to support social worker practitioners to establish plans and policies that would have helped to develop social services provision in our society so as to minimize chaos brought by street children in our communities.
