NOW AVAILABLE: Interpreting the IAR & ISA Results Recorded Webinar
If you were unable to attend the live workshop offered earlier this fall, the recorded webinar is now available. This session explores how educators can use IAR and ISA results as part of a comprehensive system of teaching and learning. Participants will learn how to interpret assessment results and identify patterns and trends in student achievement, reflect on instructional practices, and translate those insights into actionable classroom activities.
ACCOMMODATED TEST FORM INFORMATION
The Illinois Administration Platform is now available for districts and schools to begin assigning accommodated test forms for students, either manually or through file upload. Use the Spring 2027 IAR and ISA Accommodations Field Guide and related resources as the primary references when implementing accommodation updates.
Please note that locally provided accommodations should continue to be administered during testing but cannot be entered into the Illinois Administration Platform.
All third-party SIS vendors, district test coordinators, and school test coordinators are responsible for ensuring that local student information systems, data exports, and accommodation records are aligned with the Illinois Administration Platform requirements.
The Spring 2027 IAR and ISA Accommodations Field Guide, Accommodations Upload Template, and other resources are available on the Pearson Support Site and include the latest accommodation guidance and upload specifications:
TEST WINDOW DESIGNATION
To maximize student participation in the state assessment, districts and schools can use the full state testing window to administer the IAR assessment. While districts may establish a local testing schedule that best meets its needs, it is not necessary to designate a specific testing window within SIS/IWAS or report it to ISBE.
We do, however, encourage schools to assess all students who enroll at any time during the state testing window, when it is feasible to do so.
2026 IAR Reports
The 2026 preliminary reports are available in the Illinois Administrative Platform. Review the
Performance Report Scoring Guide
for details on how to access the student reports.
All reporting guides can be located on the
Pearson support site under the Reporting tab.
All other district and school reports are posted in the Illinois Administration Platform. Individuals with test coordinator access can download those reports. Refer to guidance documents for interpreting those results:
The electronic versions of the Individual Student Reports are available for download in the Illinois Administrative Platform. Hard copies will be delivered to districts the last week of August and should be sent to parents and guardians as soon as possible.
