Test results show 34.6% of Lake County students passed the Mathematics portion of the Illinois Assessment of Readiness (IAR) in the 2023-24 school year, according to the Illinois State Board of Education.
The number of Lake County students who succeeded rose by 4.1% compared to the previous school year.
Monroe County had the highest success rate across the state, with 50.0% of its students passing the Mathematics portion of the IAR. Schools in Alexander County, on the other hand, performed the worst, with 97.1% of students failing to meet test requirements.
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.Â
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.
Illinois allocated $8.6 billion to K-12 education in its 2025 budget—a $350 million increase over FY 2024, meeting the minimum required under the state’s school funding formula.
