The reason I feel that income plays a major role in children's outcomes on their assessments is because their life exposures. Children who come from families with more money are more than likely going to have someone there to make sure they are studying and also healthy. Also parents who work the lower end jobs might have to be away from home more because they need to put in the hours. Children from higher incomes are going to have been exsposed to more culture. This reminds me of that movie The Blind Side, how the character Michael Ore was just getting passed along to differnt homes, but also his education. Once he moved in tith the Tuleys he had access to a full time tutor, and a family who made sure he was rested, fed, and attending school; also teachers who wanted to help him receive a good education. Im not saying all people with lower incomes are in this situation, but they have less resources.
