What stands out at Lily Lake Grade School

Teacher staffing is the clearest operational constraint

Lily Lake Grade 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.

Student support operates inside a leaner district budget

Lily Lake Grade School's district reports $14,069 in per-pupil expenditure, at least 15% below the Illinois average of $17,042. That district-wide constraint gives the campus-level support fields added meaning: counselor loads, specialist staffing, and program access are being reported within a comparatively lean spending environment. F-33 does not publish this school's own budget, so the comparison describes district context rather than dollars assigned to this building.

Lily Lake Grade School is a mid-sized combined-grade school in Maple Park, Illinois, enrolling 275 students.

Class loads run somewhat heavier than typical: 16.2:1 puts it in the larger third of Illinois schools by student-teacher ratio.

Enrollment of 275 puts it in the smaller third of Illinois schools by headcount.

Its Resource Investment Index lands in the upper third of 3,845 scored Illinois schools.

Its student body is led by White (77%) and Hispanic or Latino (18%) (diversity index 37/100).

10.2% of students were chronically absent in the 2021-22 collection, in line with the post-pandemic national range.

Central Cusd 301 also operates Central High School (1,575 students) and Prairie Knolls Middle Sch (770 students) alongside Lily Lake Grade School.
