32% of students in Third Lake’s public schools are proficient in math, above the Illinois average (26%).

From Illinois state tests taken in spring 2021, when nearly all of students in the tested grades sat them, and the class of 2023’s four-year graduation rate, as reported to the U.S. Department of Education.
