Field Testing Participation

Field testing is a critical component in planning for future IAR testing. Each year, a small percentage of the Illinois student population is selected to participate. Please check the lists below to see if your school(s) is slated to participate. Students participating in the English Language Arts/Literature (ELA/L) field test will have a third unit added. Test administrators should use the same test administrative scripts and allow the same amount of time that they use for the other two ELA/L units.

NEW: Introducing the New Student Readiness Tool

The new Student Readiness Tool (SRT)​ engages students in learning how to navigate TestNav using elements that support visual, auditory, and kinesthetic learning. The SRT ensures fairness and inclusion for all students by showing them how to use the TestNav tools, item types, and features that will appear on the summative assessment and will therefore improve student readiness and confidence before test time.

SRT is not meant to familiarize students with the standards. Please direct students to the content practice items on the IAR support page.

TestNav System Requirements for 2023

Pearson has updated TestNav system requirements for the 2022-23 school year. Anyone using the 1.10 app will need to upgrade to the latest app for their platform to use TestNav. ChromeOS 97 will no longer be supported for use with TestNav.

Please review the technical bulletins and system requirements to ensure your school devices are ready for the spring administration. The updated TestNav application must be downloaded and installed prior to that time. 

Please call Pearson customer support at 833-213-3879 if you have questions.​

 Parent Portal

The Illinois Assessment of Readiness Parent Portal is now available for parents/guardians. The Parent Portal provides parents and guardians online access to their child’s performance on the IAR test for English Language Arts/Literacy and Mathematics. The IAR Parent Portal User Guide is available and has information on how to create an account, log in to the account, and add claim codes to access student score reports and videos of Individual Student Reports (ISRs). The portal will also allow parents/guardians to track their student’s scores from year to year, beginning with the spring 2021 results. The unique access code can be found on each student's ISR.
