A new study using new methods to examine the dynamics of wealth found that family wealth might partly explain differences in test scores of school-age children, and examined how wealth affects children's cognitive achievement at different stages of childhood.

Wealth had a stronger effect on school aged children than on preschoolers, and had a stronger association with math than reading skills.

Family wealth also was positively associated with parenting behavior, home environment, and children's self-esteem.
