Summary

GCMS High School in Gibson City, IL, is a small rural school serving 275 students in grades 9-12 as part of the Gibson City-Melvin-Sibley CUSD 5 district, and it stands out for achieving strong academic results despite serving a higher percentage of economically disadvantaged students (35.6% free/reduced lunch) than many nearby schools.

What makes GCMS truly unique is its exceptional performance with low-income students, ranking in the 99th and 95th percentiles statewide for this subgroup in recent years. This is a stark contrast to Mahomet-Seymour High School, a top-tier school just 19 miles away with higher overall test scores but a much lower poverty rate (22.95%). GCMS also achieves a high graduation rate of 92.5% while spending $19,097 per student—significantly less than smaller peers like Ridgeview High School ($25,233) and Fisher Junior/Senior High School ($20,944). However, the school faces growing competitive pressure from Paxton-Buckley-Loda High School, a similar-sized neighbor that has improved rapidly and now surpasses GCMS in 11th-grade ACT scores.

While GCMS excels in many areas, there are a few concerns for parents to note. Chronic absenteeism has risen steadily since the pandemic to 17.3%, now higher than the district average and approaching the rate at Mahomet-Seymour. Additionally, support for special education students has been inconsistent, swinging from a 1-star to a 4-star rating and back to a 2-star rating over the past three years. On a positive note, 10th graders show strong proficiency in ELA (67.8%) and math (42.4%), outperforming state averages by wide margins, though a notable "9th grade slump" in science suggests a potential curriculum gap that is successfully addressed by 10th grade.
