The Illinois Assessment of Readiness (IAR) measures how well students in grades 3-8 are progressing toward state standards in English language arts and mathematics.
Recent IAR data shows that while Illinois students improved slightly in the test, math performance remains below pre-pandemic levels. In 2024, 28.4% of students met math benchmarks, compared to 31.8% in 2019.
However, data also indicates a significant achievement gap based on race and ethnicity. The disparities were even more pronounced in math. White students achieved a proficiency rate of 38.7%, while Black students achieved 9.1% and Hispanic students 15.6%. Asian students achieved the highest proficiency rates in both subjects, hitting 68.2% in ELA and 61.4% in math.
