Figure 1 Highest effects for predictors of mathematics attainment at age 10. The effect sizes are in standard deviation units to facilitate comparison between predictors.
Preschool centers (141) were randomly chosen in six areas demographically similar to England overall. The preschool stage of the study involved children from nursery classes, playgroups, private day nurseries, centers run by a local authority, nursery schools, and integrated children's centers and, thus, included all types of preschool centers in England at the time of the study. Children's cognitive ability at ages 3 to 4 and 5 and mathematical attainment at age 10 were assessed and family data obtained by interview (11). The parental interview when children were age 3 to 4 covered learning activities enabling the creation of a home learning environment (HLE) index (11). The typical child attended preschool for 18 months part-time, and primary school for more than 5 years full-time by age 10.
