OSAS Mathematics Assessment

Oregon's Statewide Mathematics Assessments include:

NOTE: The Assessment of Essential Skills graduation policy remains suspended by Senate Bill 744 through 2027 – 2028 pursuant to the Oregon State Board of Education’s decision during its October 2023 meeting.

Assessments and Resources

  • OSAS Math Test Crosswalks (Claims, Targets, Standards, and Achievement Level Descriptors)
    These documents align the OSAS Math Test claims and targets with the Oregon K-12 Math Standards. The claims and targets can be used to design classroom lessons and district assessments. In addition, these documents provide Achievement Level Descriptors that serve as a guide in understanding the OSAS Math Test reports.
    Grade 3, Grade 4, Grade 5, Grade 6, Grade 7, Grade 8, High School
  • Smarter Content Explorer
    The following website provides interactive connections between Oregon K-12 Mathematics Standards and assessment Claims and Targets. Additional resources are located within the website: accessibility guidelines, scoring rubrics, and more. For more information on navigating and using the website, please refer to the following Smarter Content Explorer video​.

  • ​​ Assessment Resources Use Chart​
    This document provides a side-by-side comparison of training tests, practice tests, and interim assessments to help teachers decide which tool best fits their needs.​​

  • Development and Design
    Content and Item Specifications translate Oregon K-12 Mathematics Standards into assessment frameworks and evidence.

  • Mathematics Construct-Relevant Vocabulary
    Quick reference document that includes the construct relevant vocabulary for grades 3-8 and high school, sourced from the Claim 1 item specifications.

  • Oregon Mathematics Performance Task Scoring Rubrics

    Includes Performance Task Scoring Rubrics for use in preparing for the OSAS Mathematics Test.

    ​​​​4 Point Item Rubric, 3 Point Item Rubric, 2 Point Item Rubric, ​1 Point Item Rubric

  • Read Aloud Guidlines for OSAS ELA and Mathematics Tests (English)(Spanish)

    Human test readers must use these guidelines for students using Read Aloud or Read Aloud in Spanish designated support. Recommendations for use are detailed in the Oregon Accessibility Manual.

Oregon offers over 85 math interim assessments blocks (IABs) that are designed to be embedded in the learning process. Most IABs are composed of 8-15 items and take approximately 30-45 minutes for most students to complete. Other distinguishing features of Oregon’s interim assessments are:
  • IABs are fully aligned to the depth and breadth of Oregon standards
  • IABs provide smaller bundles of content that can be used as needed for “just in time” adjustments
  • IABs allow for frequent and flexible use
  • IABs can be easily embedded within mathematics unit maps (learn how!​)
  • Interim items include all accessibility resources available in Oregon’s summative assessments
  • IABs can be used outside of students’ grade level
  • IABs connect directly to instructional next steps in Tools for Teachers
For more information, please visit ODE’s Interim Assessment webpage.

  • OSAS Mathematics Sample and Training Tests​​
    Sample and Training Tests provide students and teachers with a preview of test questions.

  • OSAS Sample Items
    This site provides examples of test questions used on the OSAS Mathematics Test. Teachers, parents, students, administrators, and policymakers can experience these test items just as students encounter them.

    These sample items are not intended to be used as practice tests, but educators can use them to better understand how the Oregon Summative Assessment measures college- and career-ready knowledge and skills​.​

  • Understanding Student Scores​​​

  • Assessment Results
    The reports on this page display the percent of students meeting or exceeding the achievement standards that were in place during the academic year the results are reported.

  • Accessing Target Reports
    Target reports show the performance of groups of students on grade-level targets compared to proficiency, as well as which of these targets are relative strengths and weaknesses.

  • Achievement Standards​ (cut scores)
    ​This reference document shows the achievement standards for Oregon’s Statewide Assessments by content area and grade/benchmark level.​

​In Oregon, the 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.

In addition to the required areas, districts are encourage to consider administering local performance assessments in other skill areas as appropriate to the local curriculum. For instance, districts may choose to administer local performance assessments in any of the other areas, such as Social Science Analysis.

Scoring Guide and Feedback Forms

For local performance assessments, districts may locally develop scoring guidelines so that they can provide feedback to students, or they may use the state Scoring Guide.

Sample Tasks and Scored Student Work

  • Understanding Proficiency: Performance Tasks

    Resources to help educators develop a deeper understanding of the Oregon K-12 Mathematics Standards by analyzing student work on performance tasks. Central to these resources are samples of real student work on sample ELA and Math performance tasks.

Professional Learning

The Oregon Math Leaders Network is a community of math practitioners who work together to implement and support math teaching and learning in Oregon. Participants include teacher leaders, TOSAs, program administrators, college faculty, and math community partners. The rule of thumb: If you identify as a math leader, you are! 

We meet virtually each month to support each other personally and professionally by asking critical questions, collaborating on problems of practice, and sharing our work. Because this network spans the state, the topics of our collaboration will generally be driven by district needs. 

The 2023-24 virtual meetings will continue to take place on the third Thursday of each month on Zoom. Register now for either the morning sessions (8:30 - 9:30 am PT) or the afternoon sessions (4:00 - 5:00 pm PT).
