Cultural capital refers to non-financial social assets like education, knowledge, and speech patterns that promote social mobility. Sociologist Pierre Bourdieu theorized that cultural capital contributes to educational achievement, giving an advantage to students from the middle class whose culture and experiences are valued in schools. Studies have found that cultural capital transmitted in the home, like reading habits and museum visits, significantly impact students' exam results. However, critics note that a lack of material resources can also affect educational outcomes regardless of cultural capital. Additionally, not all working class students fail at school.
