Summary

Mundelein Cons High School serves grades 9–12 and enrolls 2,282 students in Mundelein, Illinois. Its 2025–26 results are generally above state proficiency levels, but the most important finding is that it trails nearby high schools by a wide margin on most comparable tests.

Science is the school’s strongest subject relative to Illinois: its results are 4.4 to 7.7 percentage points above the state across the three tested grades. ELA is also above state results in each grade, while math is a concern: 10th-grade math is 2 points below the state, and 9th-grade math is also slightly below. Locally, however, the picture is weaker: Mundelein is below all four nearby schools in eight of nine subject-and-grade comparisons, with scores about 16 to 28 points below nearby-school averages. Its 10th-grade math result is especially low at 35%, compared with a nearby average of 62%. Reported test scores for the school match those for the Mundelein Cons HSD 120.

Recent results are mixed. 10th-grade math fell 5 points from the prior year, and its position relative to the state worsened by 7 points; 9th-grade math improved by 8 points. Several ELA results and 11th-grade ACT results also declined. SchoolDigger ranks Mundelein 182nd of 620 Illinois schools, at the 71st percentile with 4 stars; all four nearby schools rank higher, at the 81st to 98th percentiles. The student-teacher ratio is 15.8 students per teacher (2024–25), the highest among the nearby schools. The school reported 24% free/reduced lunch eligible in 2021–22. SchoolDigger’s statewide ranking for Low Socio Economic Status Students was at the 33rd percentile, 38 points below the school’s overall percentile, and fell 33 points over two years. Its Special Education Students ranking was at the 52nd percentile, 19 points below overall, after a 30-point drop from the prior year.
