Timing of SNAP benefits can hurt kids’ grades

For schoolchildren who receive food through the monthly Supplemental Nutrition Assistance Program (SNAP), which day payment arrives can affect academic performance, new research shows.

Student scores on end-of-grade reading and math tests vary depending on how much time has elapsed since the family’s SNAP (formerly known as Food Stamps) benefit arrived, with scores peaking between two and three weeks after benefits were received.

Scores dip to their lowest point right after SNAP benefits are paid and at the end of the benefit month, the study shows.

With nearly 13 million American children receiving SNAP, the findings have broad implications, says Anna Gassman-Pines, an associate professor in Duke University’s Sanford School of Public Policy.

“Our study adds to a growing consensus that SNAP benefit levels are insufficient for many families,” Gassman-Pines says. “We also provide new evidence that this is hurting low-income children’s school performance and contributing to the academic achievement gap.”

Approximately 42 million Americans received SNAP benefits each month in 2012, the year the study examined, at a cost of $5.7 billion a month. About 30 percent of the recipients were school-aged children, and the average monthly per-person benefit was $125. The Trump administration recently proposed a 25 percent cut to the USDA program, which began in the 1960s.

Previous studies have shown SNAP beneficiaries vary their food shopping and caloric intake throughout the month, spending and eating more right after they get a new infusion of benefits, and spending and eating less when their allocations run low. The types of foods vary, too, with more protein purchased at the beginning of the month and more carbohydrates and prepared foods at the end.

Although the connections between SNAP and children’s health and school behavior have been well studied, this study is believed to be the first to show a connection between SNAP benefit timing and children’s academic performance.

As reported in the American Educational Research Journal, researchers looked at data pertaining to 147,418 North Carolina students with reading scores and 148,316 students with math scores in grades three through eight at 1,903 schools. The average family benefit totaled $462 a month.

The relationship between scores and dates of SNAP transfer were slightly stronger for reading than for math. Girls were more affected than boys, perhaps because they often have roles in food preparation. Results were consistent across racial and ethnic groups.

In addition, students’ probability of meeting grade-level proficiency on exams was 0.9 percentage point higher in reading and 1.1 percentage points higher in math at the performance peak, compared to the beginning of the SNAP month.

Although scores were only slightly different—typically a few points—”even a small difference can matter,” Gassman-Pines says. A few points can mean the difference between meeting state standards for grade-level proficiency, or falling below the level needed to advance to the next grade.

SNAP can actually raise spending on food

In North Carolina, SNAP benefits are transferred to an electronic debit card based on the last digit of the household head’s Social Security number, making the transfer dates highly variable. Those with numbers ending in “1” get benefits on the third of each month; those with numbers ending in “2” get benefits on the fifth of each month, and so on.

“In a randomly determined way, some children were taking the test after a couple of weeks of healthy eating while others were taking the test after their family had very possibly recently had less food,” Gassman-Pines says.

“This random pattern made me confident that differences in test scores were actually influenced by the timing of benefit transfers and not because of some other difference among parents or families, such as how close they lived to a grocery store.”

Possible solutions include increasing the SNAP benefit and changing the way benefits are distributed, Gassman-Pines says.

If payments were spread out over the month rather than distributed in one lump sum, families might experience less fluctuation in calories consumed from week to week. This would not help all families, but it could help some without increasing costs.
