Quizplus · Accepted Answer

Research has revealed that Head Start can lead to short-term increases in IQ and academic achievement, but these gains tend to fade over time. However, Head Start has been found to provide other important benefits for children, such as improved health outcomes and social-emotional development. There has been no evidence to suggest that Head Start reduces cultural-familial intellectual disability, and long-term increases in IQ are not typically observed.
