OnDemand Reports

IAR Spring 2024 OnDemand Reports are now available in PearsonAccessnext to those users with the district or school test coordinator role or those with report access. An OnDemand Report score is provided for each student record that received a valid score. A score is considered valid if the record has met the rules for "attemptedness" and has not been voided.

To access these reports/files:

  1. Log in to PearsonAccessnext.
  2. Confirm the correct administration dates: Illinois > 2023-2024>IL IAR Spring 2024.
  3. Go to Reports>OnDemand Reports.
  4. On the left side of the screen, you may filter by Test Name, Subject Name, Grade, or Performance Level. You may also search for specific students.

Student information can be downloaded using the print icon on the right of the ODR screen. Student lists can be downloaded for selected students as a PDF, CSV, or Excel file.

Additional information can be found in the OnDemand Report GuidancePDF Document document.

Spring 2024 IAR Corrections - Action Needed by Schools/Districts!

Assessment Enrollment Verification
District and school staff should compare this report with local records to verify all tested students are reported correctly prior to scores being posted. The report highlights students with multiple enrollments during the testing window. If the student is not on the report, immediately enroll the student in the Student Information System (SIS) during the testing window. To access this report, log in to SIS, choose “Reports” on the left, then “Student,” then “Assessment,” then “Assessment Enrollment Verification Report,” and finally “Details.”

  • The deadline for districts to add and correct school year 2023-24 SIS enrollment data is July 31, 2024.
  • Verify that report counts match your local assessment roster and the students who tested:
    • Appear on the report (i.e., enrolled in SIS during the test window).
    • Show the correct grade level at the time of testing.
    • Show the appropriate Test to Be Taken. (IDEA Indicator and Alternate Assessment must be “Yes” for DLM-AA.)
    • Show accurate First Year in U.S. School indicator (from the “EL Information” tab in SIS enrollment).

Assessment Corrections and Scores Review Procedures
Districts and schools will have until Aug. 23 to review/correct their IAR testing data. You can start entering your RNVTA codes for students who did not test on Wednesday, May 15. (RNVTA Code DescriptionsPDF Document)

Please refer to the Assessment Correction and Score Review Procedures GuidelinesPDF Document for further dates and details.

The IAR scores will be available in SIS by July 22. Districts and schools will be able to view scores and resolve any error codes that may be present at that time. The deadline for all IAR corrections is Aug. 23, 2024.

Career and College Readiness Resources

The Illinois Assessment of Readiness for English language arts and mathematics for Grades 3-8 has been linked with the Lexile and Quantile Framework to support the development of students and determine if they are on track to graduate college and are career ready. Using the Lexile and Quantile score included on the Individual Student Report, parents and teachers can utilize the enhanced resources, tools, and capabilities through our state partnership with MetaMetrics.  
  • Lexile and Quantile Hub
    This online platform provides you with easy access to more than a dozen new and enhanced reading and mathematics tools.
  • Lexile and Quantile Growth Planner
    This planner helps parents and teachers to identify the reading and math requirements needed for a desired career for students and use them to inform goal-setting.
  • Lexile and Quantile Career Database
    This helps parents and teachers to compare and describe the reading and math requirements of career interests for students.

 Test Design

​English Language Arts

The ELA/L summative assessment is available in Grades 3 – 8. Students read and analyze passages from real, authentic texts – both fiction and nonfiction – as well as multimedia. Students then draw upon what they’ve learned from these passages and multimedia, using that knowledge to respond in writing. These skills are critically important for students in college and the workplace.


The mathematics summative assessment is available in Grades 3 – 8. Students solve multi-step math problems that require reasoning and address real-world situations. This requires students to reason mathematically, make sense of quantities and their relationships to solve real-world problems, and show their understanding. Many previous assessments focused mostly on rote procedure only.

IAR Performance Levels

Results on assessments are reported for ELA and Mathematics according to five performance levels that delineate the knowledge, skills and practices students are able to demonstrate:
  • Level 1: Did not yet meet expectations
  • Level 2: Partially met expectations
  • Level 3: Approached expectations
  • Level 4: Met expectations
  • Level 5: Exceeded expectations
