Statewide Alternate (Extended) Assessment

Oregon's Extended Assessments are alternate assessments PDF 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 PDF 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 names: Does not meet, Nearly meets, Meets, and Exceeds.


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.


Sample Tests

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

    Individuals who were Qualified Assessors or Qualified Trainers last year or individuals who are interested in becoming a QA or QT this year are required to access this site in order to review the Updates, training, and pass the appropriate proficiency test to re-qualify or qualify to administer the Extended Assessment to students for the current school year.

Assessment Development and Transitions

The 2012-2013 Oregon Extended Assessment test blueprints in reading, writing, mathematics, and science elaborate current assessment priorities.
