“…Just as Duncan, Featherman, and Duncan (1972) argued that the content of IQ came to be those skills which are most highly demanded in highstatus occupations, so Bowles and Gintis and later Bourdieu (1984) and Lareau (2003) argued that teachers and employers rewarded those whose socialization reproduced the cultural behaviors associated with the professional and upper classes. Farkas et al (1990) has shown that test scores and such noncognitive behaviors as student work habits, disruptiveness, and absenteeism almost completely explained differences in course grades by gender, race/ethnicity, and poverty status for middle school students. Rosenbaum (2001) made a similar demonstration that test scores and non-cognitive factors measured on high school seniors can explain most of the differences by gender, race/ethnicity and class in high school grades and subsequent educational attainment.…”
