Delaying their initial entry to school can cause some children to actually fall behind their peers in learning. Some studies have shown differing early childhood academic achievement results when comparing children from low-income families with those living in middle-income homes Children from low- income homes tend to begin school with weaker skills than their peers from more advantaged backgrounds. Holding young children back a year before they begin their academic career is sometimes thought to help them mature before beginning school. This practice may actually backfire for some of those children from low-income households. During the additional year at home, these children are thought to miss opportunities to cultivate the basic skills that they could develop while taking part in a learning environment-skills suggested to be absent in some low-income families.   Consider a revision which replaces the terms low-income and middle-income with the terms poor and normal.
