Cons HSD 230

Cons HSD 230 has three high schools serving grades 9–12: Carl Sandburg, Amos Alonzo Stagg, and Victor J. Andrew. Across nine comparable subject-and-grade measures, their average proficiency was 57%, versus 47% statewide—about 10 percentage points higher. Each school’s average was above the state result on all nine measures. Math showed the largest average advantage over the state, at 12 percentage points, compared with 9 in ELA and 8 in science. The clearest area-wide finding is consistent performance above state results, even though scores vary among schools and subjects.

Sandburg stands out overall, averaging 60% across the nine measures and leading six, including all three grade 10 measures. Its strongest result was grade 10 PreACT science at 66%, while its grade 9 math score of 54% was the lowest in that comparison. Andrew averaged 56%; it led grade 11 ACT ELA and grade 9 and 10 PreACT math, and had the highest graduation rate at 98%. Stagg averaged 55%, the lowest of the three, but still exceeded the state in every measure. Its 92% graduation rate was lower than the other schools’ but above the state’s 90%.

Results declined slightly overall from the prior year: the average change was down about 1 percentage point per school-measure comparison, and the area’s advantage over the state narrowed by about 1 point. Sandburg had the largest net decline across its nine measures; Stagg’s net change was slightly positive, while Andrew’s was slightly negative. SchoolDigger ranks Sandburg 96th of 620 with 4 stars, Andrew 126th with 4 stars, and Stagg 138th with 4 stars. Student–teacher ratios are close, ranging from 14.7 at Stagg to 15.6 at Sandburg. The reported free/reduced lunch eligible shares, from 2021–2022, were 35% at Stagg, 21% at Andrew, and 18% at Sandburg; these figures offer context, not an explanation for school results.
