What is IAR testing?

The Illinois Assessment of Readiness (IAR) is a state-mandated assessment test for students in grades three, five, seven, and nine. This is the first time that Illinois has taken this type of standardized test. The IAR will be administered in spring 2018, and it is necessary for you to be prepared before it happens or your school could face consequences.

The IAR test assesses Illinois students’ reading, writing, math, and science skills in English language arts (ELA) and mathematics as well as Critical Thinking strand grades 3-8.

This article will explain what the IAR's purpose is and what grade levels will be tested on them. It also explains how the statewide assessment was developed to measure student readiness for college and careers rather than their grade level performance.

IAR test practice is recommended, but it is not mandatory. Parents can write a statement to excuse their children from IAR test prep. However, if students do not practice for the IAR test and they do poorly on it, their schools will face consequences, such as a school grade of “F” for the school year.
