Summary

Lanphier High School serves grades 9–12 and enrolls 1,117 students in Springfield, Illinois, as part of Springfield School District 186. Its most pressing challenge is student attendance: in 2025–2026, 62% of students were chronically absent, compared with 39% districtwide, 24% statewide and a 31% average among four nearby schools. Though the rate has improved from 78% in 2021–2022, Lanphier still has the highest chronic absenteeism among those nearby schools.

Test proficiency is below the state and district in every reported subject, grade and exam, and is generally well behind nearby-school averages. Grade 11 ACT ELA is a particularly stark example: 11% of Lanphier students were proficient, 39 points below the state and 34 points below the nearby-school average. Science is the relative bright spot, though results remain below peers: Lanphier’s grade 10 science proficiency was 23%, just above Springfield Southeast’s 21%, while its grade 9 science result was 19%, above Southeast’s 17%. ELA is the weakest subject overall, with the largest average gaps from state and nearby-school results.

Some measures are improving, but Lanphier remains low in the latest comparisons. Its graduation rate rose from 55% in 2021–2022 to 72% in 2025–2026, yet remains 13 points below the nearby-school average and the lowest among those schools. SchoolDigger ranks Lanphier at the 6th percentile statewide, with 0 stars, down from the 20th percentile in 2023–2024. Its student-teacher ratio is comparatively low at 14.2 students per teacher, versus a nearby-school average of 16.1. Lanphier reports 74% free/reduced lunch eligible in 2024–2025, compared with a 51% average among nearby schools with a comparable same-year measure; this is context, not an explanation for results. For Disabled Students, SchoolDigger’s statewide percentile was 39 in 2023–2024, then fell to 20 in 2024–2025; the overall school percentile fell from 20 to 10 over that span. These percentiles are comparative rankings, not direct measures of individual students.
