In the 1950s, the Supreme Court confronted a fundamental question about educational equality with Brown v. Board of Education: Was it enough for Black children to have access to a public school, even if that access was limited to segregated schools that “allowed” Black students? Or did they have a right to attend public schools on equal terms with everyone else? Ultimately, the Court rejected racial segregation, recognizing that educational opportunity could not be equal when children are forced to attend separate schools based on race. As Chief Justice Earl Warren wrote in his opinion, “Where a State has undertaken to provide an opportunity for an education in its public schools, such an opportunity is a right which must be made available to all on equal terms.”But why does equal access on equal terms matter? Why did it matter when Black children had other schools they could attend, and why would they want to attend schools that wished to reject them anyway? According to the Supreme Court, even if two schools were comparable, state-sponsored segregation sent a message to Black children that they were inferior. This message harmed children’s development in ways that, as Chief Justice Earl Warren wrote, were likely “never to be undone.” Black families challenged a system that made race the basis for deciding where their children could go, even when other schools were available, because the harm was the message sent by the government’s endorsement of discrimination.Brown did not resolve every question about educational equality, but it gives us a strong framework for understanding why equal access to public programs matters.The case before the Court now, St. Mary Catholic Parish v. Roy, is about a different question: whether Colorado can require religious providers participating in its publicly funded universal preschool program to comply with nondiscrimination rules. Colorado’s program provides public funding to public and private preschools, includ
