How Denkmann Elem School compares with Illinois and U.S. medians
What stands out at Denkmann Elem School
Teacher staffing is the clearest operational constraint
Denkmann Elem School's enrollment sits away from the most extreme size bands, but its reported student-teacher ratio is heavier than most Illinois schools. That isolates staffing load as a more useful concern than raw campus size. A high ratio does not establish weak teaching or outcomes, yet it can indicate less adult capacity per enrolled student. The remaining federal indicators show whether support staffing and program access offset that pressure.
Attendance is a relative strength
8.1% of Denkmann Elem School students were chronically absent in the 2021-22 civil-rights collection. On its face, that is a comparatively low historical rate, though this page does not treat it as a current national benchmark or guarantee current-year performance. Here, attendance is a more distinctive signal than the presence or absence of any single specialist role.
Denkmann Elem School is a mid-sized elementary school in Rock Island, Illinois, enrolling 356 students.
Class loads run somewhat heavier than typical: 16.2:1 puts it in the larger third of Illinois schools by student-teacher ratio.
With 356 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 White (40%) and Hispanic or Latino (22%), more mixed than most schools in the state (diversity index 74/100).
Counselor availability sits well past the ASCA benchmark, roughly 356 students sharing each counselor, though short of the most stretched campuses.
Attendance holds up well here: only 8.1% of students were chronically absent, below the typical post-pandemic national figure.
Its district draws 21.6% of revenue from federal sources, an above-typical federal share that tends to track a higher-need student population.
Among Rock Island's elementary schools, it stands alongside Eugene Field Elem School (496 students): Denkmann Elem School is smaller than that campus by headcount and runs leaner classes (16.2:1 vs 21.6:1).
