# Study: Delaying Kindergarten Has Few Longterm Benefits
Parents who delay their children's kindergarten entry, a practice known as redshirting, rarely see lasting academic gains, according to new research. The strategy appears to offer short-term advantages that fade by upper elementary school.
Redshirting involves keeping a child home for an extra year before kindergarten, typically when parents worry about their child's readiness, maturity, or size compared to classmates. The practice remains common in the United States, with some estimates suggesting 10 to 15 percent of kindergarten-eligible children are held back annually.
The study examined children's academic trajectories across multiple years and found that any initial boost from entering school later disappears. Children who were redshirted performed slightly better in early kindergarten and first grade on measures like letter recognition and number skills. By third grade, however, this advantage vanished. Researchers found no meaningful differences between redshirted children and those who entered kindergarten on schedule when comparing math and reading achievement.
The findings matter because redshirting decisions often reflect socioeconomic privilege. Families with more financial flexibility can more easily afford to delay kindergarten entry. This can widen gaps between wealthy and lower-income students, even though the delayed entry itself produces no lasting benefit.
Experts note that kindergarten readiness depends less on age and more on exposure to language, early literacy activities, and social interaction. Children who attend quality preschool programs often start kindergarten better prepared than older peers without such experience.
The research suggests parents should focus on school quality and their child's individual development rather than age alone. Children born near kindergarten cutoff dates need careful assessment, but age-based delay strategies offer little payoff. Schools and districts can better serve all students by offering strong kindergarten programs that meet children where they are, regardless of entry age.
