SES and race on school success
-Middle- and high-SES students, on average, earn higher grades, score higher on standardized tests of achievement, and complete more years of schooling than do students from lower-SES homes. This is because children in poverty lack many of the advantages enjoyed by other children, such as proper nutrition and health and attending inadequate schools
-data on school achievement indicate that, on average, African American and Hispanic students tend to perform at lower levels, receive lower grades, and score lower on standardized tests of achievement than do Caucasian students. In contrast, Asian American students tend to receive higher grades than Caucasian students do. A lot of this difference is due to socioeconomic factors. Some cultures may also perceive school success as relatively unimportant
