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.

*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.

2025-26 ISA Testing Window

  • March 2 - April 30, 2026

Students will no longer take a separate Illinois Science Assessment in Grade 11.

The Illinois State Board of Education (ISBE) will adopt the ACT to serve as the federally-required science accountability assessment for Grade 11, effective with the 2024-25 school year, thereby reducing overall testing time. The state administration of the ACT will include English, mathematics, reading, science, and writing.

ISBE has also developed an FAQ about the state’s transition to the ACT to help answer questions you may be receiving from parents and families. We encourage you to share the FAQ​ with your school communities.

ISBE will follow up with a more technical FAQ to answer additional questions from administrators once we have executed the contract with ACT and have final information to share.

    • 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.​​​​​​
