How Longwood Elem School compares with Illinois and U.S. medians
What stands out at Longwood Elem School
Scale and staffing sit near the state mainstream
Longwood Elem School is neither an extreme outlier in enrollment nor in student-teacher ratio among Illinois schools. Its profile therefore turns on the other dimensions rather than on scale alone: economic need, counselor coverage, program access, attendance, and district finance. This middle placement is useful because it prevents the campus from being mislabeled as unusually large, small, crowded, or teacher-dense when the federal comparison does not support that claim.
Attendance is the dominant support signal
Longwood Elem School's 38.2% chronic-absence rate is more consequential than a generic staffing label: at least one quarter of students missed 10% or more of school days in the 2021-22 collection. That level can affect instruction, counseling demand, and continuity even when other reported resources look ordinary. The dataset records the scale of absence but not its causes, so it should prompt a current-year question rather than a conclusion about school management.
Longwood Elem School is a mid-sized elementary school in Naperville, Illinois, enrolling 346 students.
At 13.3:1, its student-teacher ratio sits close to the Illinois median, within a few percentage points of the 14:1 state norm, neither notably crowded nor notably small.
With 346 students, its enrollment sits close to the Illinois median campus size.
Its Resource Investment Index sits near the middle of the pack among 3,845 scored Illinois schools.
Its student body is led by African American (40%) and Hispanic or Latino (25%), more mixed than most schools in the state (diversity index 72/100).
Chronic absenteeism is elevated: 38.2% of students missed 10% or more of school days (2021-22 Civil Rights Data Collection).
