Statewide Alternate (Extended) Assessment


Oregon's Extended Assessments are alternate assessments designed specifically for students with the most significant cognitive disabilities. The decision to administer Oregon's Extended Assessment (the alternate assessment) can only be made by the student's IEP team -- including the parent. Because Extended Assessments are based on alternate achievement standards with content that is reduced in depth, breadth, and complexity, test results from these assessments are not comparable to results achieved on the state's general assessment, in spite of the similarity in performance category.


  • Extended Assessment District Secure Website
    Qualified Assessors (QAs) and Qualified Trainers (QTs) must have a username and password (provided by their district security administrator) to log on to this site and access the Extended Assessment application for the Extended Assessment test materials (Resource Materials) and to enter the student’s Extended Assessment scores (“Data Entry Instructions”).
  • Qualified Trainer and Qualified Assessor Expectations 07/11/2013
    To administer Extended Assessments to students in the State of Oregon, educators must be appropriately trained as either a Qualified Assessor or a Qualified Trainer of the Extended Assessments.
  • Oregon Extended Assessment Administration Manual 9/28/2016
    This manual is intended for educators and parents who are interested in a general overview of the Oregon's Extended Assessments - including a description of its architecture (organization and format as well as a review of decision-making for implementation), general administration, and scoring procedures. An overview of this year's Extended Assessments and the administration of such will be covered at the Qualified Assessor and Qualified Trainer Training meetings in November and under the "Training" tab on Oregon's Training & Proficiency website.

Achievement/Performance Standards

Achievement (also called “Performance”) Standards define the requirements for a student to meet and exceed on Oregon's Extended Assessment by content area and grade. An achievement standard is an objective definition of a certain level of performance, in a content area at a particular grade, in terms of a cut score or a range of scores on the Extended Assessment psychometric scale. All Alternate Achievement Level Descriptors assume that student curriculum and assessment is based on content standards that have been reduced in depth, breadth, and complexity. This means that Extended Assessment results cannot be used to compare to the results of students who are taking the General OAKS assessment and who are in the same enrolled grade. Best practices now include adoption of cross-subject cross-grade (“General Policy Definitions”) and grade-level Achievement Level Descriptors prior to standards setting.

  • 2013-14 & 2014-15 Cut Scores and Benchmarks Comparison
    With the transition to an Extended Assessment based on new state content standards in ELA (i.e., Reading, Writing), Math, and Science, ODE is aware that IEP teams may need information that compares or "equates" the Reading, Writing, Math, and Science cut scores of the "old" Extended Assessments with the "new" ones. With that in mind, the tables of these cut scores and benchmarks (or Levels) comparing 2013-14 and 2014-15 are provided here.


  • Extended Assessment: Interpreting Scaled Scores Guide 11/02/2015
    This guide explains how to interpret scores for the Oregon Extended Assessment in terms of annual performance, interpreting reading and writing sub-scores, making growth determinations, and rated observations for very low functioning students using the Oregon Observational Rating Assessment.
  • Oregon Extended Assessment Guidance 12/16/2015
    ODE has updated guidance on the selection process used by IEP teams in determining whether a student should take the Oregon Extended Assessment. This updated guidance takes into account the current policies regarding the new Smarter Balanced Assessment and the focus on Oregon’s assessments appropriately measuring the student populations they were designed to measure.

Sample Tests

Sample tests demonstrate the types of questions students might encounter on the Oregon Statewide Extended Assessment administered each year.


Assessment Development and Transitions

  • Extended Assessment Vendor Decision
    Following a process that started a few years ago, precipitated by new Common Core State Standards and the identification of consortia charged with the development of new alternate assessments based on alternate achievement standards, Oregon revisited its Extended Assessment vendor options. Per stakeholder recommendation and subsequent review by ODE, the State Board of Education has approved the recommendation to continue with our current vendor Behavioral Research and Teaching/University of Oregon for 2016-17 forward.
