What is it about?

We were interested in the effect that child-care attendance has on child development. In particular, we examined the number of hours per week children attended center-based child-care. We found that the more children attended child-care, the less environment played a role in their school readiness, to the benefit of genes.

Why is it important?

Home environment varies a lot from a child to another, with some environments being harmful for child development. The results of our study show that child-care could buffer negative effects from such low-quality environments, helping children develop the skills required for school.


It was interesting for me to be involved in this project because I am a mother of two children who do not attend child-care. I think it helped me nuance the results so that the keep-home message is not merely that child-care is best for children, but rather that it reduces the role of environment on child development. In other words, child-care is thought to mainly benefit children from low-quality home environments.
