The class of 2013 in Washington state is the first that must pass an end-of-course exam in algebra or geometry in order to graduate.
However, statistics from the 2011-2012 school year by the Office of Superintendent of Public Instruction shows that less than 80 percent of all students last year passed a test.
Most students pass either the algebra or geometry test by the end of 10th grade, and make-up tests are offered. But if seniors still haven't passed, they can submit a set of math problems the state provides as an alternative, called a Collection of Evidence.
High school seniors also have to pass the High School Proficiency Exams in reading and writing.
Last year, the graduation rate in Washington state was 76.6 percent. Meaning almost one-fourth of the class of 2012 didn't graduate.
Graduation requirements will continue to ramp up in coming years, with an additional math test and a science test joining the requirements.
