Educational Attainment
Educational attainment refers to the highest level of formal education that a person has completed, usually measured by years of schooling or by qualifications such as secondary diplomas, degrees, and doctorates. It is one of the most widely used indicators in sociology because it strongly predicts occupation, income, health, and political participation. Peter Blau and Otis Dudley Duncan’s status attainment model showed that parental education and occupation influence children’s attainment, and William Sewell and colleagues’ Wisconsin model added aspirations and significant others. Pierre Bourdieu emphasized cultural capital as a hidden driver, and Gary Becker’s human capital theory treated education as an investment that raises productivity and earnings. Randall Collins argued that credential inflation means that qualifications increasingly signal status rather than skill, while Michael Spence’s signaling theory offered a related economic account. Raymond Boudon and Richard Breen and John Goldthorpe explained class differences through decisions under constraint. Claudia Goldin and Lawrence Katz traced the race between education and technology. Gender gaps have reversed in many countries, with women now more likely to complete higher education. Educational attainment remains central to research on mobility, inequality, labor markets, and life chances.
