Unequal achievement at school among students is mostly caused by 'social class' factor. It means that students from upper class often receives privileges in education and career opportunities rather than students from lower class. Hence, the social class issue has hampered students' ability to achieve academically. According to Bernstein, children from the upper and middle classes have an easier time adjusting to the school system. This might happened because they were exposed to early education at home which is similar to school's academic subjects. Unlike students from lower class, their first education is primary school. Only some of them have great parents that prioritize early education at home.

In addition, students from lower class are more likely to drop out of school earlier and disinterest in pursuing their studies in tertiary education because it requires large sum of money to spend on a child's education. The parents will not take the risk for that. Thus, the lower class students did not get the opportunity to change their family socioeconomic status by getting better and secure job. 

In my opinion, it is understandable for the parents for not supporting their children in education because of their financial instability. However, the bigger risk we are willing to face, the better result we might get. Plus, government has provided some incentives and supports for B40 family in many areas. For example, PTPTN and various scholarships to assist the students from lower class. Therefore, we can conclude that unequal achievement among students causes by social class are no longer valid since the era has changes. Parents has no reason to obstruct their talented and genius children from education just because of financial problem since there many ways to overcome that one problem.
