It belongs to Lake Central School Corporation, a district ranked 27th of 374 in Indiana — the 93rd percentile — with a 5-star rating. Because this is the only elementary school in the ZIP code, the comparison points below are the district, the state, and the school's own prior-year results.
Academically, Kolling is strong overall but uneven by subject. Math is its clear strength: all-grades proficiency was 70.68%, far above the district's 56.51%. Third-grade math reached 74.07% and fourth-grade math 68.09%, both well ahead of the state's 51.9% and 52%. English Language Arts is the weaker area. All-grades ELA was 50.6%, below the district's 57.35%, and it slipped from 55.38% the year before. Even so, both third- and fourth-grade ELA results stayed above their state figures. Science was close to the district at 54.61% and comfortably above the state's 43.8% in fourth grade. The school ranked 187th of 1,015 in 2025–2026 — the 82nd percentile with 4 stars — down from 136th in 2023–2024, though it has held 4 stars for three consecutive years.
Attendance is a genuine standout: chronic absenteeism was just 6.7%, less than half the district's 16.2% and the state's 16.7%. The free/reduced lunch rate is 14.93%, per-student spending is $11,019, and the student-teacher ratio is 14.6. For parents, the takeaway is a well-regarded school in a highly rated district, with excellent math results and unusually strong attendance. The main area to watch is reading and writing, where results trail the district and have declined year over year.
