Twenty years ago, 11 brave parents, aided by lawyers, scientists, and scholars organized by NCSE, brought suit in a federal court to defend the integrity of the public science classroom. The result: a decision that teaching "intelligent design" in public schools violates the U.S. Constitution. To commemorate the 20th anniversary of Kitzmiller v. Dover, NCSE has developed a quiz to test your knowledge. When you're done with the quiz, you can check out more on the Kitzmiller v. Dover trial from NCSE.
