Smart students don’t boost other classmates’ grades
Being in a classroom full of “the best and brightest” students may not help marginal ones, according to new research that contradicts popular theory.
The study shows that students in a middle school gifted and talented program performed no better on national tests than a similar group of students who didn’t qualify for the program.
“This paper is part of a growing body of literature suggesting that just because you have stronger peers doesn’t necessarily mean you are going to perform better,” says Scott Imberman, associate professor of economics and education at Michigan State University.
Gifted and talented programs have grown in popularity, with more than 3 million students now enrolled nationwide. The study, published in the American Economic Journal: Economic Policy, provides an important first step in understanding the effects of gifted and talented programs on students.
Using a sample of more than 14,000 fifth-graders in an urban school district, researchers analyzed students’ standardized test scores in math, science, reading, social studies, and language arts.
The study targeted a group of children who qualified for a gifted and talented program by barely meeting a certain threshold based on past academic performance. Their test scores were compared to the students who just missed meeting the threshold—in other words, students who were very similar academically.
The marginal students in the gifted and talented program showed no improvement in test scores over the non-qualifying students in any of the five subjects.
The study also looked at gifted and talented students who were picked in a lottery for a “magnet” program, which emphasizes a more intensive, specialized curriculum.
The researchers compared test scores of the magnet students who won the lottery to the gifted and talented students who lost the lottery and found no significant difference in four of the five subjects: math, reading, social studies and language arts. The magnet students did show improvement in science.
