An LSU researcher found that high school students’ standardized test scores in math and English fall for up to three years following a fatal shooting.

Math scores dropped by close to 5 percent and math scores by around 4 percent, according to a paperco-authored by Louis-Philippe Beland, LSU assistant professor of economics. The paper will be published in the journal Educational Evaluation and Policy Analysis.

Beland’s research also shows ninth-grade enrollment drops by close to 6 percent after a shooting, suggesting that middle school students and their parents try to avoid the school where a shooting took place. The impact of shootings was greater in poorer schools.

The paper by Beland and Dongwoo Kim, a postdoctoral fellow in the University of Missouri’s Economics Department, was cited in a story about schools spending more on security by The Wall Street Journal. A U.S. Department of Education survey found of roughly 1,400 public schools nationwide found 75 percent had at least one security camera during the 2013-2104 school year. During the 2009-2010 school year, 61 percent of the schools had one or more security cameras.

Beland told the Journal it’s surprising that the impact of a shooting is so large. Students at more affluent schools may do better because their schools have counseling services and other resources that poorer schools don’t, Beland said.
