What Parents Should Know

At 190 students, Illini Central High School is on the smaller side. That usually buys more individual attention and teachers who know every kid by name, with the trade-off of fewer electives and extracurriculars than a larger school can staff. Ask what activities it actually offers.

Test scores at Illini Central High School sit below average, but its growth scores are strong: students here make above-average progress year over year. The raw numbers haven't caught up, but a school that keeps moving kids forward is doing the harder, more important work.

At 9.5:1 students to teachers, Illini Central High School sits well below the national average. Smaller classes like that usually mean more one-on-one time between students and teachers.
