Educational disadvantage occurs when some children benefit less from education than their peers due to characteristics outside their control. It is self-perpetuating, leading to lower lifetime income, employment and marriage opportunities. It causes a gap between skills and jobs, increases lower socioeconomic classes, and reduces purchasing power. The document reviews literature on the causes of and potential solutions to educational disadvantage, finding that short-term programs have limited effectiveness and that more long-term research is needed to identify the most effective solutions.
