Isu Laboratory Schools operates 2 public schools serving 1,045 students, placing it among the smallest districts in Illinois. The school portfolio breaks down into 1 high, 1 combined schools, a small enough portfolio that most families will interact with nearly every campus in the district at some point. These enrollment and school figures come from the NCES Common Core of Data (CCD) 2024-25 release, and the district is based in Mclean County.
Academic infrastructure includes 1 of 2 schools offering Advanced Placement (13 AP courses district-wide), a 208:1 student-counselor ratio, that meets the ASCA-recommended benchmark, and 22.5% chronic absenteeism from the 2021-22 Civil Rights Data Collection. Demographically, the student body averages 70.7% White, 8.9% Hispanic or Latino, 8.3% Asian across the district's schools.
Its largest campus is University High School, enrolling 624 students (58% of the district's total enrollment).
University High School accounts for 57.6% of all Isu Laboratory Schools student enrollment
That is an overwhelming concentration, leaving the rest of Isu Laboratory Schools a distant remainder — means Isu Laboratory Schools-wide averages can mask substantial variation outside the dominant entity. Grade band: high. A single dominant campus often anchors a district's program offerings and staffing patterns; the share helps explain why district-wide averages may not reflect the typical neighbourhood-school experience. When one entity dominates a region's footprint, its programmatic and budget decisions effectively set policy for a majority of the affected population.
Isu Laboratory Schools student-counselor ratio is 208:1 — low (typically associated with meeting or exceeding the American School Counselor Association (ASCA) recommended 250:1 benchmark, which correlates with stronger college and career counseling capacity)
student-counselor ratio is the simplest comparative metric but it does not capture the full picture: the ratio counts FTE counselors against total enrollment, districts that contract intervention or social-emotional staff outside the counselor classification may be under-counted Lower values often correlate with smaller scale and population characteristics rather than higher resource budgets per se.
Isu Laboratory Schools chronic absenteeism rate is 22.5% — near the typical range (US average ~28) — aligned with the national post-pandemic baseline of roughly 28% chronic absenteeism
chronic absenteeism rate is the simplest comparative metric but it does not capture the full picture: a student is chronically absent if they miss ≥10% of enrolled days for any reason, illness, family obligations, or disengagement Variation between sub-units within Isu Laboratory Schools is typically wider than the Isu Laboratory Schools-aggregate figure suggests.
