 Answers to these two fundamental questions enable philosophers to construct a conception of equality of educational opportunity. Of course, philosophical controversies remain even supposing the content of the conception can be settled. Some of these controversies concern clashes with other values, including that of the family and diversity: What limits do parental rights put on the pursuit of equality of educational opportunity? Is affirmative action required by or contrary to equality of educational opportunity? Other issues arise when we try to interpret what equality of educational opportunity means for those with disabilities, or when we attempt to define “merit” and “native talent potential”.
