The classes of 2006 in California, Arizona, and Utah are those states' first that must pass high school exit exams to earn diplomas. Twenty-three states now have such exams. Maryland will require a graduation test for next year's class, and Washington state will do so for the class of 2008. In most states with such a requirement, students take the high school exit exam for the first time in sophomore year. The content on the tests is usually at a 10th grade level. Students who fail usually have several opportunities to retake the tests. In many states, students must pass tests in more than one subject. This article briefly describes these states' graduation requirements.
