Using an unanticipated policy reform in Mexico that shifted 4 months the cutoff date for elementary school eligibility in 2006 and information on academic performance of 15-year-old students from the Programme for International Student Assessment (PISA) 2018 survey, who entered first grade in 2006, this paper estimates the effects of starting…

Setting the age for starting elementary students at 60 months old has been a hotly debated topic in Turkey since the Grand National Assembly passed an education reform bill as Law No. 6287, known to the public as the "4+4+4 regulation." At the outset of its implementation, students who started first grade in school year 2012-2013 had an…

This paper describes a 2016 pilot study undertaken in Uganda to document the real repetition rate in Primary 1 classes and to examine the relationship between repetition in Primary 1 and attendance in pre-primary education. The study explored knowledge and practice about the age of entry for children into pre-primary education and Primary 1. It…

This research critically investigated the implementation in Turkey of starting elementary-school first grade at age 5 (60 months) according to teacher feedback. While the study is designed as qualitative, a kind of single case study approach is used with a group of 50 volunteer first-grade teachers serving in 15 elementary schools in the Eskisehir…

In this paper, we estimate the effect of pupil's relative age within the first grade of primary school on mathematics and reading test scores at age 15. The main objective is to evaluate the long-term causal effect of relative age in the first grades of primary school on pupil's test in 16 different countries. We use the national rule for…

California's Kindergarten Readiness Act of 2010 established transitional kindergarten (TK), the first year of a two-year kindergarten program for students affected by the change in the birthdate cutoff for entry into kindergarten from December 2 to September 1. This final report from the program's evaluation focuses on results from a five-year…

European American students are more likely delayed entrance in kindergarten than African American students. This study examined whether age at kindergarten entry influences the reading proficiency skills of African American and European American students at the start of kindergarten, at the end of first grade, and at the end of third grade. Using…

California's Kindergarten Readiness Act of 2010 established transitional kindergarten (TK), the first year of a two-year kindergarten program for students affected by the change in the birthdate cutoff for entry into kindergarten from December 2 to September 1. This fifth short report in a series highlighting findings from the Study of…

Although it is well established that Black male students are underrepresented in gifted educational programs in the United States, due to a scarcity of longitudinal prospective research, little is known about the protective factors at the child, family, and school level that increase the probability of Black male students being identified as…

Two studies examined the effect of school entrance age on the social acceptance and self-perceptions of kindergarten and first-grade children. Teachers' ratings and peer nominations described initial social problems in youngest children, which were overcome by first grade. Found no differences in self-reported school adjustment, loneliness,…

Examined the effects of age at entrance to first grade on success in elementary school, using a set of demographic, social, and early experience variables as covariates. Concluded that entrance age was a far less powerful predictor of academic achievement than were socioeconomic factors. (Author/GR)

Assessed the reading and mathematics abilities of kindergartners and first graders in the fall and spring of the school year. Found that younger first graders made as much progress over the year as older first graders and more than older kindergartners. Findings demonstrated that entrance age was not a good predictor of learning or academic risk.…

Examined school entrance age effect on academic achievement and social-emotional adjustment among 137 fourth graders. Found that differences between 73 oldest and 64 youngest subjects, identified in first grade, persisted in part to fourth grade. Younger subjects scored lowest in mathematics and oral and silent reading comprehension; were slower…

The effects of age at entrance into school on subsequent elementary school performance were studied in a cohort of children who started grade 1 in the Dallas school system (Texas) in fall 1981. Most of the subjects were born on or after September 1, 1974 and before September 1, 1975; the spread of ages was 1 year. A total of 3,028 male and 3,019…

This paper reviews literature and research on the effects of age of initial entry into schooling, citing over 20 studies from the 1930's through the 1970's relating entrance age to academic success and personality development. Studies investigating the effect of early entry into first grade on academic achievement have indicated that not only…
