Summary:
ZIP code 61753 has one high school, Lexington High School, serving grades 9–12 and enrolling 163 students. Most importantly, its 2025–2026 results are above Illinois results in every comparable subject-and-grade test; the 10th-grade mathematics result is suppressed.
Because Lexington is the only high school in the list, it is both the highest and lowest locally, rather than a school that can be ranked against nearby peers. Its strongest state comparisons are in 9th-grade PreACT Secure science, at 68% versus 47% statewide, a 21-point advantage, and 9th-grade ELA, at 78% versus 62%, a 17-point advantage. The closest comparison is 11th-grade ACT mathematics: 42% versus 40%, just 2 points higher. Graduation is another strong result: 100% in 2025–2026, compared with 90% statewide.
Results rose sharply for 9th graders from the prior year, while most matched 10th- and 11th-grade results fell: 9th-grade scores increased by 14 points in ELA, 25 in mathematics and 18 in science; 10th-grade ELA and science declined by 9 and 7 points, and 11th-grade ACT results fell by 7 points in ELA, 14 in mathematics and 1 in science. SchoolDigger’s ranking improved from 174th of 697 schools (75th percentile) in 2023–2024 to 109th of 620 (82nd percentile) in 2025–2026.
