Summary:
Zip code 60559 has five Westmont-area schools, from elementary through high school: three elementary schools, one junior high and one high school. Four have test-score results in the supplied data; C E Miller Elementary School has none. In 2025–2026, the scored schools generally performed above state proficiency rates, though Maercker Elementary School was nearly even with the state in all-grades ELA and the clearest exception to that overall strength. The most important takeaway is that results vary by school and subject, but the other reported IAR schools were well above the state in both ELA and math.
Westmont High School stands out on 11th-grade ACT: proficiency was 84% in ELA, 72% in math and 82% in science, beating state rates by 34, 32 and 35 percentage points. Westmont Junior High School led the reported all-grades IAR ELA results at 86%, 29 points above the state, and its eighth-grade science rate was 73% versus 52% statewide. Among the scored elementary schools, J T Manning Elementary School exceeded Maercker in all seven shared-grade comparisons, by 6 to 27 points. Maercker’s third-grade ELA rate, 45%, was below the state’s 48%; its all-grades math rate, however, was 51% versus 40% statewide. SchoolDigger’s 2025–2026 rankings also place Westmont High at the 95th percentile, Junior High at the 91st, Manning at the 86th and Maercker at the 56th.
Recent IAR changes were mixed: Junior High rose 8 points in ELA and 5 in math from 2024–2025 to 2025–2026, while Manning fell 3 and 2 points; Maercker’s ELA was nearly unchanged and its math fell 4 points. Across the three schools with all-grades results, the average advantage over the state narrowed by about 1 point in ELA and 2 in math. SchoolDigger’s earlier rankings show Maercker falling from the 82nd to the 56th percentile between 2023–2024 and 2025–2026, while Junior High rose from the 86th to the 91st. As context, free/reduced lunch eligibility in 2024–2025 was 50% at Maercker and 39% at Westmont High; these figures describe student populations, not reasons for score differences.
