About the Oregon Statewide Summative

The Oregon Statewide Assessment System (OSAS) testing is a comprehensive program of summative content assessments designed to provide information about what students know in core academic areas. It is currently used for English Language Arts (ELA), Mathematics, and Science. This replaces the OAKS and Smarter Balanced testing.

Our curriculum is focused around actual material that a student is likely to see on the upcoming Oregon Statewide Summative test. Nationally known for delivering high quality and affordable materials that help students improve their scores, we provide you both paper-based instruction and easy to use online test preparation.
