Higher socioeconomic status (SES) is correlated with greater academic success due to increased parental involvement, academic resources, and early language exposure. By age 3, children from high SES families speak over 1,100 words on average compared to just 525 words for low SES children, leading to large gaps in IQ and reading readiness. Teachers also tend to have higher expectations for and form stronger relationships with students from high SES backgrounds, negatively impacting the experiences of low SES students as early as kindergarten.
