This piece of research project has demonstrated that there is a gap in educational achievement between parents' access to social capital and children's educational outcomes in a global context by examining England, United States and China specifically. Through examining educational resources, from in-school factors, such as facilities, teacher quality and teacher to student ratio, to out-of-school factors, such as family structure, socioeconomic status, and community values. This research paper evaluates several theories of social capital in the hopes of providing an explanation for why this achievement gap exists.The literature review outlines an analogy between Diamond's (1999) geographic luck theory and the education system in a global context. The review of the literature also examines the relationship between parents' access to socioeconomic background and academic performance across diverse backgrounds. This paper shows the importance of all kinds of resources to academic achievement and how social capital plays a consequential role in the students' educational outcomes.
