Oregon Statewide Assessment System (OSAS) Science Assessment
 - Previously OAKS Science
Oregon joined a collective of states via a memorandum of understanding in the development of our Next Generation Science Standards-aligned science assessments. This effort is organized by the American Institutes of Research (AIR). The states involved in the collective are sharing items and resources as we work toward our first NGSS-aligned operational science assessments in 2018-19.

The OSAS Science Assessment will contain questions aligned to the 2014 Oregon Science Standards (NGSS).  Items are presented independently or as a cluster.  Each cluster is designed to engage the test taker in a meaningful scientific activity aligned to the standard and contain: a phenomena to give context and engage student interest, background information and/or data, a task description, and multiple questions.  Clusters and items are computer scored.

OSAS Science will be assessed at grade levels 5, 8, and HS.  The 2020-2021 assessment window  for grades 5 & 8 opens March 4 and closes June 4.  The window for high school opens on January 5 and closes on June 4. Your child's school will keep you apprised of test dates.
