Factors impacting Student Achievement Research

Students in high-poverty school districts learn as much during the school year as their peers in more affluent districts, according to a nationwide study of 3000 students. Researchers found that achievement gaps may be fueled more by nonacademic barriers -- hunger, unstable housing, violence in the home -- that some students face outside of school.
