OLYMPIA, Wash. (AP) — Washington schools Superintendent Randy Dorn says the state is getting carried away with the exams high school students are required to pass before they graduate.

Students in the class of 2012 were required to pass two exit exams. That goes up to five for the class of 2015: reading, writing, biology, algebra and geometry.

Dorn said Thursday he'll ask the Legislature next month to reduce that to three: a reading-writing test, biology and algebra.

Dorn says exit exams are costly and over-testing creates a system in which too much time is devoted to preparing.

Exit exam costs about $30 each. And, alternative portfolios for failing students to demonstrate ability cost about $400.
