This paper sought to shed light on the beliefs, aspirations and values in relation to education that shape parental ways of involvement among Chilean urban lower-middle-class parents. Using the capability approach as the main theoretical framework and a critical epistemology, the discussion focuses on the way in which the pre-eminence of instrumental and positional dimensions of education arguably places limitations on how education is understood and valued; sets boundaries for parental involvement and overloads families. This situation ultimately diminishes the power of education to disrupt intergenerational cycles of disadvantage among Chilean urban lower-middle-class families.
