Oregon Statewide Assessment System (OSAS)

  • Oregon's statewide assessment system (OSAS) includes tests administered annually by subject matter and grade. Oregon public schools test students in English/language arts and math in grades 3 through 8 and 11, and in science in grades 5, 8, and 11. Additional assessments include an English language proficiency assessment (ELPA Summative) for our English learners, the Extended Assessment for our students with special needs and the Kindergarten Assesment to evaluate incoming kindergarten student's skills in Early Literacy, Early Math, and Approaches to Learning. In addition to state tests, schools administer local performance assessments (to fulfill the Local Performance Assessment Requirement) and to give students feedback on their learning and academic progress, as well as provide opportunities for students in select grades to take national assessments like the NAEP and PSAT.
