How Landmark Elem School compares with Illinois and U.S. medians
Slightly above state median
15.8:1 - 1.8 above the Illinois state median of 14:1, indicating larger average class loads than typical schools in the state.
Landmark Elem School enrolls fewer students than most Illinois schools, yet its student-teacher ratio is still on the heavier side of the state distribution. Small enrollment therefore does not translate into more teacher capacity per student here. That makes staffing capacity, rather than campus scale alone, the useful interpretation. The counselor, attendance, and program indicators below help show whether the pressure is narrow or part of a broader resource constraint.
Landmark Elem School's available federal support indicators do not reveal an extreme in advanced-course access, specialist staffing, chronic absence, or IDEA enrollment. The most responsible reading is therefore component by component rather than a sweeping verdict: current counseling availability, health support, program schedules, and attendance policy still warrant direct confirmation. Missing or middle-range federal fields are not evidence that services are either strong or weak.
