In compliance with federal testing requirements, Illinois will administer a science assessment to students enrolled in a public school district in grades 5 & 8. The assessment will be administered in an online format and is aligned to the Illinois Learning Standards for Science incorporating the Next Generation Science Standards(NGSS), which were adopted in 2014.

This Illinois Science Assessment (ISA) page will be updated as information becomes available. Students who participate in the DLM alternate assessment will be assessed in science in grades 5 & 8 by the DLM-AA. Students taking the DLM-AA will not take the ISA exam. The ISA is not an alternate assessment.

New, Unified Performance Levels and Right-Sized Proficiency Benchmarks for IAR, ISA, and ACT

The Illinois State Board of Education (ISBE) has adopted new, research-informed, and right-sized assessment performance levels to give students, families, and educators better data on academic achievement and college readiness. Prior performance levels mislabeled many students in elementary and high school, often indicating that students were less academically successful and prepared for college than they actually were. The new, unified levels correct long-standing misalignment between Illinois’ state assessments and other real college and career readiness expectations.

2025-26 ISA Testing Window

  • March 2 - April 30, 2026
ISA Practice Tests are availible on the QuISBE practice exam platform.
To gain access to QuISBE, please fill out the QuISBE Participation SY2025-26 form.
Pearson will provide further access instructions after the participation form is submitted.
(Note: QuISBE is not the testing platform for the summative ISA exam)
QuISBE is a practice test platform for the Illinois Science Assessment (ISA). QuISBE provides 5th and 8th grade students with the opportunity to interact with science content similar to the ISA prior to the spring summative assessment. ISA practice tests will be accessible in QuISBE from September 22 through the end of the school year. These practice tests can be completed in a single class period or over several days and include both machine-scored and hand-scored items. Student machine-scores will be available in QuISBE once all items are completed. Teachers will use a rubric to hand-score any constructed response items. Students may take each practice test multiple times during the school year to monitor their progress. 

*Google is discontinuing support for native, legacy Chrome Apps. In response to this change, TestNav will retire the legacy TestNav Chrome App.

Pearson has updated the TestNav system requirements for the 2025-2026 school year. Please review the technical bulletins and system requirement pages below to ensure your school devices are ready for the spring administration.

Schools will be required to use the new TestNav Web App for ChromeOS. The old TestNav app must be uninstalled and then the new app needs to be installed prior to Spring 2026 testing.

    • The 2016 assessment window opened on May 1, 2016, giving some districts limited time to administer the assessment before the conclusion of the school year. In addition, schools that utilized devices running Apple iOS operating systems experienced significant technology issues that required converting to a paper administration. In some places, paper materials did not arrive in time for students to take the assessment before the school year ended. Low participation rates in some schools and districts should not be interpreted as a lack of effort or diligence on their part in light of the obstacles some faced.​​​​​​
