Summary:
ZIP code 62573 has one high school, Warrensburg-Latham High School, serving grades 9–12 with 336 students. Its results show a strong graduation rate but a notable academic concern: in 2025–26, 95% of students graduated, 6 percentage points above Illinois, while grade-11 ACT math proficiency was 22%, 18 points below the state. That math result is the school’s clearest area to ask about.
With only one school in the list, there is no local top or bottom school to compare; Warrensburg-Latham stands out in different ways against state results. Its 2025–26 ELA results were close to state averages, while its math and science averages were lower: 34% versus 39% in math and 44% versus 48% in science. Grade-11 ACT science was also below state proficiency, at 40% versus 48%, while ACT ELA was nearly even, at 51% versus 50%. Chronic absenteeism was 27%, above the state’s 24% and the district’s 18%, so the high graduation rate coexists with an attendance concern.
Results improved relative to the state overall from 2024–25 to 2025–26, but not consistently. Grade-10 PreACT math proficiency rose 11 points, and its gap with the state narrowed by 9 points; grade-10 science rose 10 points, narrowing its gap by 11. In contrast, grade-11 ACT math fell 5 points, and its gap widened by 5 points. SchoolDigger gives Warrensburg-Latham three stars and ranks it 293rd out of 620 Illinois schools. Its student-teacher ratio was 17.7:1 in 2024–25, and 39% of students were free/reduced lunch eligible that school year; these figures offer context, not an explanation for results. Because there is only one listed school, this ZIP’s data cannot show how it compares with nearby high schools.
