Final answer:
The Coleman Report identified family background as the most influential factor in determining educational success(option b).
Step-by-step explanation:
According to the Coleman Report, the factor deemed most influential in determining educational success is b) Family background.
The Coleman Report, officially known as "Equality of Educational Opportunity," was a comprehensive review of the state of education in the United States and the various factors affecting it. Led by sociologist James S. Coleman, the report concluded that family background and socioeconomic status were more significant in predicting student achievement than differences in school resources like funding or teacher qualifications.
The report highlighted that children from families with a higher socioeconomic status typically have access to more educational resources and support, providing them with a significant advantage over their peers from lower socioeconomic backgrounds. This finding emphasizes the role of socioeconomic factors in creating disparities in educational success and continues to influence discussions about education policy and reform.
