Conservative lawmakers across the U.S. are pushing to introduce more Christianity to public school classrooms, testing the separation of church and state.

Seventy years ago this week, the U.S. Supreme Court ruled separating children in schools by race was unconstitutional.

What’s less certain, however, is whether Hall's education in Detroit’s long-troubled school district was so awful, so insufficient, that it violated his constitutional rights. The Detroit case was filed in 2016 on behalf of Hall and other students who attended rodent-infested, crumbling schools that lacked certified teachers and up-to-date textbooks. A similar case was filed on behalf of students in Rhode Island last year, asserting that they were denied a basic civics education. “It would lay down a huge marker in terms of how all the states across the nation fund or don’t fund their schools,” Black said. “Every school in the country would be affected,” said Michael Rebell, a Teachers College, Columbia University professor who brought the Rhode Island case.
