Summary:
Zip code 60123 has one high school, Larkin High School, serving grades 9–12 with 2,174 students in School District U-46. In 2025–2026, its proficiency rates were below state rates in all nine reported grade-and-subject comparisons, with gaps of 22 to 29 percentage points. Graduation was 79%, compared with 90% statewide. The most striking concern is chronic absenteeism: 55% of students were chronically absent, versus 24% statewide and 30% districtwide.
There is no separate top or bottom school within the ZIP code because Larkin is the only high school listed. Its results do stand out against statewide benchmarks: SchoolDigger gave it one star and ranked it 549th of 620 Illinois high schools, at the 11th percentile, in 2025–2026. The largest state proficiency gap was in 10th-grade English language arts, where 25% were proficient at Larkin versus 54% statewide; the smallest was in 11th-grade English language arts, at 28% versus 50%. Mathematics was comparatively closer to state results across the three grades, but Larkin remained below the state in every grade.
Results changed unevenly from 2024–2025 to 2025–2026: 11th-grade ACT proficiency rose by 4 to 5 percentage points across subjects, while 10th-grade ELA fell by 9 points and science by 8 points; 9th-grade math rose by 9 points. Across the matched grade-and-subject results, the average gap from the state widened slightly—by less than one percentage point. SchoolDigger’s percentile ranking also declined, from 26th in 2023–2024 to 18th in 2024–2025 and 11th in 2025–2026. Context measures include a 15.3 student–teacher ratio and 65% free/reduced lunch eligible in 2024–2025; these figures describe the school but do not explain its outcomes.
