As the result of inadequate socialisation in the home
Intellectual and linguistic skills
Lack of intellectual stimulation and enriching experience
Lack of reasoning or problem-solving skills
Language spoken by low-income black American families is inadequate for educational success (ungrammatical, disjointed, incapable of expressing abstract ideas)
Children who do not speak English at home are held back
Official statistics show that children with English as the first language were only 3.2 points ahead of those without English as their first language in 2010
Indian pupils do very well, despite not having English as their home language
Attitudes and values
Lack of motivation in many black children
Socialisation into a subculture that instils a fatalistic 'live for the day' attitude that does not value education
Family structure and parental support
Many black families are headed by lone mothers, depriving children of adequate care and a male role model
High rates of lone parenthood and lack of positive male role models lead to underachievement of some minorities
Black Caribbean culture is less cohesive and less resistant to racism, leading to low self-esteem and underachievement
Sewell's view
It is not the absence of fathers as role models that leads to black boys underachieving, but the lack of father nurturing or 'tough love'
Black boys turn to street gangs, which present a media-inspired role model of anti-school black masculinity
Academic successful black boys face pressure from peers who view them as 'selling out to the white establishment'
Black students do worse than their Asian counterparts due to cultural differences in socialisation and attitudes towards education
Critical race theories argue that it is not peer pressure, but institutional racism within the educational system itself that systematically produces the failure of many black boys
Asian families
Have a supportive family structure and an 'Asian work ethic' with high value placed on education
Adult authority in Asian families is similar to the model that operates in schools, leading to more respectful behaviour towards adults and greater parental support for school policies
White working-class families
Have lower levels of aspiration and achievement, potentially due to a lack of parental support
Teachers report poor levels of behaviour and discipline in working-class schools, despite the fact that children receive free school meals
White working-class parents are more likely to have negative attitudes towards education, compared to ethnic minority parents who see education as a way to get ahead in society
Street culture in white working-class areas can be brutal, making it hard for students to succeed in school
Compensatory education
Aims to compensate children from 'culturally deprived' backgrounds
Critics of cultural deprivation theory argue that it ignores the positive effects of ethnicity on achievement, and that black underachievement is due to racism rather than lack of self-esteem
Critics see cultural deprivation theory as a 'victim-blaming' explanation, and suggest alternatives such as multicultural education and anti-racist education
