Summary:
ZIP code 62690 has one high school, North Mac High School, serving grades 9–12 and enrolling 361 students. Its most important takeaway is that every reported 2025–2026 proficiency rate was below the Illinois rate.
There is no second local high school to compare: North Mac is both the highest- and lowest-performing school in the ZIP by default, so a meaningful local ranking is not possible. Against Illinois, the school’s reported proficiency gaps ranged from 8 percentage points below the state in grade-11 ACT science to 25 points below in grade-10 PreACT Secure science. Grade-11 ACT results averaged 11 points below state results, while grade-10 PreACT results averaged 19 points below. Graduation was closer to the state rate: 89% at North Mac versus 90% statewide. By contrast, chronic absenteeism was 27% versus 24%, and dropout was 4% versus 2%.
Results changed unevenly, with gains in some areas and declines in others: grade-11 ACT mathematics rose 6 percentage points from 2024–2025 to 2025–2026, while ACT ELA fell 8 points and grade-9 PreACT ELA fell 15. North Mac narrowed its gap with the state in three of seven matched comparisons but fell further behind in four. SchoolDigger’s ranking history also shows a lower relative standing: 56th percentile and 3 stars in 2023–2024, then 29th percentile and 1 star in 2024–2025, and 22nd percentile and 1 star in 2025–2026. In 2024–2025, the school’s student–teacher ratio was 16.7, and 53% of students were free/reduced lunch eligible. These figures provide context, but the one-school ZIP offers no local peer comparison.
