The case is part of a wave of lawsuits over the quality of schools in more than a half-dozen states. The suits could serve as road maps for advocates in other states amid a nationwide teachers’ movement and a push in some state legislatures for more school funding.

The legal complaints have different areas of focus — from school funding to segregation to literacy — but all of them argue that the states are violating their constitutions by denying children a quality education.

Such lawsuits were filed in past decades, but the recent cases show a renewed energy for using the courts to fight for better education, and they may signal an end to a period when many courts, after the last recession, seemed unwilling to require states to spend more money on schools.

“The courthouse doors are in effect open again,” said David Sciarra, executive director of the Education Law Center, which has argued school funding cases in New Jersey and has filed amicus briefs in several of the current cases. “What we’re seeing are the beginnings of a broader conversation about what the right to an education should look like.”

Advocates are focused on state courts because of roadblocks at the federal level: A 1973 Supreme Court decision found that unequal school funding was not a violation of the United States Constitution, which does not mention education. Last month, a federal judge in Michigan ruled that “access to literacy” was not a fundamental federal right for students in the troubled Detroit school system.
