Effect of school population socioeconomic status on individual academic achievement

The relationship between the socioeconomic status (SES) of peers and individual academic achievement was examined in this study. This question was investigated while a variety of sociodemographic factors were being controlled, including a student's own SES. Student SES was measured by using participation in the federal free/reduced-price lunch program as an indicator of poverty status, and parental educational and occupational background as a measure of family social status. These measures were aggregated to the school level to define the SES of the peer population. Student achievement is a factor score of the three 10th-grade components of the Louisiana Graduation Exit Examination. Peer family social status in particular does have a significant and substantive independent effect on individual academic achievement, only slightly less than an individual's own family social status.
