Interim Tests

Oregon Interim Assessment System

The Oregon Statewide Assessment System includes multiple, equity-centered resources that help address education and community partner questions: summative tests, designed for systems improvement and accountability purposes; interim tests, designed to support teaching and learning periodically throughout the year; and formative assessment practices, designed to support students in the moment-to-moment process of learning. The Oregon Balanced Assessment Graphic (PDF) displays the relationship between these components, the Oregon State Standards, and college and career readiness. As Oregon's districts prepare for summer programs, it is important to remember that ODE provides a statewide interim assessment system and Tools for Teachers in English language arts, mathematics, and science. Take a look at the Teaching, Learning, and Assessment Tools For Addressing Students' Unfinished Learning brochure for more detail!
