The Illinois Assessment of Readiness (IAR) is the state assessment and accountability measure for Illinois students enrolled in a public school district. IAR assesses the New Illinois Learning​ Standards Incorporating the Common Core and will be administered in English Language Arts and Mathematics.

IAR assessments in English Language Arts and Mathematics will be administered to all students in grades 3-8.​

UPDATE: July 21, 2021​

IAR Corrections—Action Required!

The IAR scores are now available in SIS. District staff will have until August 3rd to make corrections in SIS so that the file can be returned back to Pearson by August 6th. Please update/correct all RNVTAPDF Document records and check for errors in reports and match all “unassigned" scores.

Please refer to the following guide to assist with your corrections:

If you need assistance with the IAR Scores, contact the ISBE Help Desk at 217-558-3600, Option 3. If you have questions about testing in general, contact the Assessment Division at 866-317-6034 or assessment@isbe.net​​.

Important: Technology Update!

Pearson has updated the TestNav system requirements for the 2021-2022 school year. Please review the technical bulletin and system requirement pages below to ensure your school devices are ready for the upcoming Fall (if applicable) and Spring testing administrations.


The TestNav app must be downloaded and installed prior to Fall 2021 and Spring 2022 testing.

Learning Renewal Interim Assessments

If you are interested in participating in the Learning Renewal Interim Assessments, please respond to LRIAssessment@isbe.net. We encourage you to take full advantage of this opportunity.

Benefits to using the Learning Renewal Interim Assessment:

  • Provides timely or immediate individualized diagnostic information to the teacher.
  • Will only take about 45 minutes to administer each content area.
  • Offers useful data to teachers so they can adjust their instruction and allow for more individualized support.
  • Can be customized to match the scope and sequence of the district's curriculum.
  • Will be administered three times per year so that you can actually see student growth.
  • Allows for student mastery because it is computer adaptive.
  • It is a “best practice" toward learning recovery.
  • It is free to school districts, which allows for equity and access for districts that cannot afford interim assessments locally.  

You may access more information and resources on the ISBE Learning Renewal Interim Assessments website, as well as the webinar presentation and recording.​

Important 2021 IAR Administration Update!

All Students Taking an Online Test Form Will Take Three (3) Test Units for the ELA Assessment.

All students who are scheduled to be administered the online IAR assessment will be given a shortened 3rd session. Schools should prepare to allow between 10-20 minutes for students to complete. No headphones will be needed for this portion of the test. This session will be composed entirely of multiple-choice items and will not be used in the calculation of a student score. Test Administrators should use the same test administration scripts they use for other ELA/L sessions.​
