Oregon’s Statewide Science Assessments include computer-based assessments at grades 5, 8, and high school, as well as local performance assessments at grades K-High School.
Provides information for Oregon teachers about the number of items and the content to be assessed on the OSAS Science Assessment
This reference document shows the achievement standards for Oregon’s Statewide Assessments by content are and grade/benchmark level

This document contains specifications for writing science assessment items aligned to the 2014 Oregon Science Standards (NGSS) based on the Framework for K-12 Science Education. The document is not intended to replace the standards, but to present guidelines for the development of items used to measure the standards.
Item type tutorials show users how to navigate the items and tools available while taking an online assessment. While testing, item type tutorials are accessible to students throughout the assessment.
Sample tests provide students and teachers with a preview of test items to gain familiarity with item types as well as the functionality of features on the computer-based test.

Scoring Guides for sample tests can help teachers understand how test items will be scored on the Oregon Science Test.
In Oregon, the Local Performance Assessment Requirement states that school districts shall administer one or more performance assessment each year to all students in grades 3 through 8 and in high school in: mathematics, scientific inquiry, speaking, and writing.
Performance assessments must be a standardized measure (e.g., activity, exercise, problem, or work sample scored by a common scoring instrument, such as the official state scoring guides or another scoring guide adopted by the district) that is embedded in the school curriculum and evaluates the application of students’ knowledge and skills. Work Samples, scored using the official state scoring guide, are just one example of acceptable performance assessments. Districts have substantial flexibility when it comes to planning the performance assessments that will be used to fulfill this requirement.
This reference document describes the requirements for Local Performance Assessment administration.
