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 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 and mathematics. A science interim assessment system is available for district purchase. Take a look at the Teaching, Learning, and Assessment Tools For Addressing Students' Unfinished Learning brochure for more detail!
