C a Henning School, Troy IL - Test Scores & Data

Original Research by School Decision on C a Henning School

C A Henning School is a public elementary school serving pre-kindergarten through fifth grade in Troy, Illinois, part of the Triad Community Unit School District 2. The school enrolls a small to mid-sized cohort of students spread across seven grade levels, with the largest classes in the fourth and fifth grades. The student body is predominantly white, with smaller populations of multiracial, Hispanic, and Black students, and Asian and Native Hawaiian students each representing a very small share. No data on free and reduced-price lunch eligibility or special education and English learner populations was available.

In mathematics, the school's proficiency rates show a pattern of strength in the lower elementary grades that narrows as students advance. Third graders reached proficiency at a solid rate, fourth graders performed at a comparable level, but fifth graders saw a notably steeper decline in proficiency. This downward shift in mathematics performance at fifth grade is worth noting; a parent may want to look into further with the school what instructional or support strategies are in place for students making that transition. English language arts results tell a different story. Proficiency rates rise from third through fifth grade, with fifth graders showing particularly strong performance. The school administered science testing in fifth grade, where proficiency rates fell below the reading and math averages, suggesting this may be an area where additional resources or instructional attention could strengthen outcomes.

The school's overall proficiency index across all tested subjects and grades positions it in the top quartile among districts in Madison County, a genuine strength that reflects consistent output across multiple measures. Test participation rates were nearly universal where data was reported. Proficiency rates at sixth grade and beyond were not available because the school does not serve those grades; graduation rate data does not apply for the same reason.

Troy itself is a small city on steady growth, functioning as a commuter community for the St. Louis region while working to maintain local character. The housing market shows moderate prices and rents relative to national benchmarks, with new residential development active through subdivisions like Homes of Liberty Place, Hampton Glen, and an approved Town Center mixed-use project. Employment is distributed across small Main Street businesses, logistics and warehousing operations, and state highway maintenance services. In April 2025, Triad voters approved a substantial zero-rate-change bond referendum to replace the aging middle school, expand career and technical education facilities, add classrooms, and make district-wide improvements to safety, security, and accessibility. Because the bond is structured not to increase the tax rate, it represents a major long-term investment in school facilities without raising the tax burden on new families, a material consideration for those deciding whether to move into the area.

Graduation rate (ACGR) reflects the federally published Adjusted Cohort Graduation Rate for the most recent year available. We refresh this data annually at the close of each academic year in June. The federal source publishes a banded rate (for example, "90-94%") instead of an exact number for cohorts small enough to risk identifying individual students. The state distribution chart, where shown, plots every school in the state with a published rate or band; schools whose rate is federally suppressed are excluded. Where the federal source publishes a band rather than an exact rate, the school is placed within its band using a stable, ID-derived offset, so its position is consistent across visits.
