Centro Boliviano de Investigación y de Desarrollo Socio Integral (CBIDSI), Beni, Bolivia Researchers often need to know the parental school attainment of adult subjects. When researchers cannot ask parents about their school attainment, they must ask adult offspring about the school attainment of their parents. We assess the accuracy of answers provided by adults about the school attainment of their parents with data from a native Amazonian society in Bolivia (Tsimane'). Offspring overestimate the school attainment of their parents. They also report inaccurately other human capital attributes of their parents (e.g., writing skills, fluency speaking Spanish, practical indigenous knowledge of medicinal plants). Results mesh with findings from the United States about the lack of reliability of adults' self-reports about parental school attainment and with prior research among the Tsimane' suggesting significant misreporting of other outcomes (e.g., age, income, parental height).
