Annual Notice for State Testing:

Oregon Statewide Assessment System (OSAS) Annual Notice

In 2010, Oregon adopted higher K-12 standards in English Language Arts and Math to ensure all students move from grade to grade with the academic knowledge and skills necessary for success beyond high school. The state tests: challenge your child to think critically, go beyond multiple choice and ask your child to explain their answers, act as a snapshot of your child’s progress, and help us identify schools that need additional supports to ensure more students are meeting higher standards.
