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)

The influence of age of entrance to first grade on subsequent rate of scholastic development was tested in this longitudinal investigation. Forty-one pairs of boys and forty-nine pairs of girls, matched according to sex, intelligence, and socioeconomic status, were subjects. The mean chronological age of late entrants was 81 months, opposed to 72…

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.…

Investigated the effects of kindergarten schedules and preschool experience on elementary school students' success. Results indicated that children who attended preschool experienced greater success in elementary school than those who did not. Childrens' participation in full-day kindergarten was positively related to their school performance…

When high ability students (N=19) who had entered college before 15 years of age were compared, 50 years later, with equally intelligent students who entered college between 16 to 20 years of age, results found both groups equal in psychosocial adjustment and longterm achievement though younger college students were more often rated as high…

A study was made to determine whether or not kindergarten entry age is a factor in academic failure. The 457 seventh- and eighth-grade students who were subjects in the study had attended Fairfax County, Virginia, Public Schools since kindergarten. Although the subjects were born during 1970, they were classified as younger and older on the basis…

This study examined whether school entrance age was related to academic and social performance and whether the proportion of students referred to various programs correlated with age. Older students received more referrals for gifted evaluation, younger students received more placements in pre-first grade, and boys received more referrals for…

As part of a larger Slovene longitudinal study on the impact of the preschool institution on the child's development and his or her school achievements, effects of the age at entry to preschool on children's language were explored. The sample included 82 children, who were divided into two groups depending on their age at entry to the preschool…

To evaluate the long term impact of developmental placement, a longitudinal study was initiated with over 500 subjects from a variety of school settings across the state of Michigan. Three groups of subjects were selected: (1) children recommended for a "growth year" before entering kindergarten who followed the recommendation, thus…

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 longitudinal study identified hard-to-manage older toddlers and younger preschoolers, assessed the developmental course and prognostic significance of their difficult behavior, and delineated family factors possibly associated with early and persistent problems. Obtained from parents, teachers, and observers, cross-situational and…

This 10-year study compared the achievement of 3 samples of students designated at-risk for school failure and 1 sample deemed not at risk, and followed a transitional first-grade school readiness program (SRP) population from prekindergarten through eighth grade to identify contextual factors associated with student progress. At-risk samples were…

Investigated effects of kindergarten schedules and prior preschool attendance on elementary children's academic achievement, incidence of grade retention, and reception of special education services in 32 Ohio school districts. In this statewide longitudinal study, children who attended preschool prior to kindergarten had greater success in…

Measures of preschool cognition and indicators of family socioeconomic status predicted school enrollment for children in four Guatemalan villages. For children who went to school, socioeconomic status and preschool abilities were associated with age-at-entry, and with the number of grades passed and the maximum grade attained through age seven.…

The impact of date of birth on cognitive test scores is well documented across many countries, with the youngest children in each academic year performing more poorly, on average, than the older members of their cohort (see, for example, Bedard and Dhuey (2006) or Puhani and Weber (2005)1). However, relatively little is known about the driving…
