Figure 1 (IMAGE) University of California - San Diego Caption The findings are based on a longitudinal study in which the researchers examined time parents spend with their children from ages three to five alongside the children’s test scores when they were ages eight to 14. The researchers also find more time parents spent teaching to children from ages three to five (up to three hours or more a week) correlated with better test scores when the children are ages eight to 14. For instance, teaching three or more hours predicted 6 percent higher scores in English for children in fourth grade, relative to teaching one hour or less.
