Illinois Assessment of Readiness

The Illinois Assessment of Readiness (IAR) is a standardized test designed to measure students' progress in key areas like reading, math, and science. It helps educators and parents understand how well students are learning the curriculum and meeting learning standards at their grade level. The results inform instruction and identify areas where students may need additional support, ensuring education is effective and equitable. The assessment is administered statewide to provide a consistent measure of student achievement across Illinois schools.
