A new study out of Miami University of Ohio, set for publication in American Economic Journal: Applied Economics, concludes that third-grade retention significantly reduces annual earnings at age 26. While temporarily improving test scores, retention increases absenteeism, violent behavior, and juvenile crime, and reduces the likelihood of high school graduation.

The goal of such policies is to ensure a solid foundational “floor” for literacy before students transition from learning to read to reading to learn in the fourth grade.
Proponents argue that the short-term boost in test scores, often reflected in the National Assessment of Educational Progress (NAEP), provides students with the necessary reset required for future academic success.
However, the new study introduces a longer-term perspective by tracking retained students through age 26. Analyzing decades of data from Texas, researchers found that while third-grade retention can lead to temporary gains in test scores, those benefits often diminish or disappear by the eighth grade.
The study also suggests that the initial academic “bump” may be offset by later challenges, including increased absenteeism and a higher risk of juvenile justice involvement during the teenage years.
Economic data from the study is particularly striking, showing that the long-term impact of being held back can follow a student into adulthood. The research found that at age 26, individuals who were retained in the third grade earned an average of $3,477 (19%) less per year than their peers who were promoted.
This suggests that the psychological and social disruptions of retention, such as being older than one’s classmates, may have a more lasting influence on life outcomes than the temporary boost in literacy metrics.
As Maryland leaders move forward, the challenge lies in balancing these conflicting data points. The state’s plan focuses on immediate intervention to prevent students from falling behind in the early years, while the latest research urges policymakers to consider the “total life cycle” of a student.
The central question for the Class of 2035 and beyond is whether the state can replicate the “Mississippi” reading gains while simultaneously mitigating the long-term graduation and earnings risks identified in the Texas research.
