Interim Assessments

Oregon Interim Assessment System

The Oregon Statewide Assessment System has three components: summative assessments, designed for accountability purposes; interim assessments, designed to support teaching and learning throughout the year; and formative assessment practices, designed to support classroom-based formative assessment processes. The Oregon Balanced Assessment Graphic (PDF) displays the relationship between these components, the Oregon State Standards, and college and career readiness.
