• Oregon Statewide Assessment System (OSAS)

    In 2014-15 Oregon transitioned from the Oregon Assessment of Knowledge and Skills (OAKS) to the Oregon Statewide Assessment System (OSAS), which is based on Smarter Balanced Assessment for English Language Arts and Mathematics in grades 3 to 8 and 11.  The state continued to transition away from OAKS with its Science assessment in 2018-19 when it began using the Next Generation Science Standards (NGSS) for 5th, 8th, and 11th grade.

  • Practice Tests

    The OSAS Practice Tests are available online and represent what is expected to be the full length and rigor of the operational assessments.  Parents, students, and teachers may all freely access these sample questions to become familiar with the structure and content of the assessments. No score is given at the completion of the practice test.
