Children's health status is one of the basic foundations in successful learning. Children who have difficulties with their health in general may be less able to participate in the classroom, may be prone to more frequent absences, and therefore may be at-risk learners; whereas, children with sound general health may be at an advantage (Shonkoff 1992). America's Kindergartners (West et al. 2000) reported that 51 percent of children are considered by their parents to be in excellent general health as they enter kindergarten and 32 percent are reported in very good general health as they enter kindergarten. What, then, is the relationship between children's health at kindergarten entry and their spring kindergarten and first grade cognitive achievement?
