The culture, traditions, beliefs, social roles, and environment of the student influence the student’s performance and are factors that need extra consideration and study when dealing with the core causes of achievement gap. It would be for the researcher’s advantage that he should look into the lives, environment, economic condition, and practices of the disadvantaged minority to ascertain and identify specific cultural differences that can help explain the differences of the child-parent relationships between ethnic group families.Cultural differences shaped the child’s behavior and motivation to become achievers. The authors Jencks and Phillips argue that a child belonging to the Black family do not have much motivation and encouragement from their parents because of the lack of understanding about the benefits of education and obtaining academic skills The lack of awareness resulted to Black children going to school with little vocabularies than their White counterparts. Studies claimed that students with parental involvement such as homework assistance show more progress in school . In comparison, the disadvantaged minority consists of single parents have to spend more of their time looking for money to cope up with their household economics and other needs rather than staying and getting involve with their child’s homework . The minority group also consists of parents that do not understand nor speak English well. The study points two major causes of the child’s difficulty namely unavailable English speaker at home and lack of parental involvement for homework.
