Summary

Illini Central Grade School is an elementary school located in Mason City, Illinois, serving students from kindergarten to 5th grade. The school is part of the Illini Central CUSD 189 district, which is ranked 588 out of 811 districts in Illinois and has a 1-star rating from SchoolDigger.

Academically, Illini Central Grade School has consistently ranked in the bottom half of Illinois elementary schools, with proficiency rates below the state average in both English Language Arts and Mathematics. For example, in the 2024-2025 school year, only 30.8% of students were proficient or better in English Language Arts, compared to the state average of 53.1%. In mathematics, 36.1% of students were proficient or better, compared to the state average of 38.5%. When compared to nearby schools, such as those in the Lincoln Education Service District 27 and Greenview CUSD 200 districts, Illini Central Grade School generally performs worse in both subjects.

Despite having a relatively low student-teacher ratio and higher per-student spending than the state average, Illini Central Grade School has experienced high chronic absenteeism rates, ranging from 9.6% to 26.3% in recent years, which is significantly higher than the state average. This, combined with the school's consistent underperformance, suggests that the school may be struggling to provide a high-quality education to its students and address the factors contributing to its challenges.
