This paper provides evidence on the effect of local prescription opioid use on academic achievement of 3rd-8th graders between 2009 and 2018. Using county fixed effects models, I find that when counties have higher levels of prescription opioid use, students score lower on standardized assessments two to three years later, with variation by…

This action research study examined the impact of a summer literacy program on summer reading setback. Gaining Ground is a summer intervention program designed primarily for economically disadvantaged students in Grades K-5.
