Elementary Schools in Geneseo CUSD 228

The three elementary schools in Geneseo CUSD 228 serve kindergarten through grade 5, with Northside Elementary School also serving pre-K; enrollment ranges from 334 to 364 students. In 2025–26, the schools’ average proficiency was 61% in English language arts (ELA) and 43% in math, compared with state averages of 56% and 40%. ELA is the stronger area overall, but results vary considerably by school. The clearest shared challenge is grade 5 math: all three schools scored below the state’s 36% proficiency rate.

Northside stands out in ELA, with 68% proficient—12 percentage points above the state—while Millikin Elementary School leads grade 5 science at 67%, 19 points above the state. Southwest Elementary School has the lowest ELA result at 51%, 5 points below the state, and the lowest grade 5 science result at 35%, 13 points below. Science results span 32 points across the schools. Math is more tightly grouped overall: Millikin’s 44.1% narrowly tops Southwest’s 44.0%, while Northside is lowest at 39%, just below the state.

Recent changes favor ELA over math: the school-average ELA score rose by 4 points from 2024–25, while the math average fell by 9 points, narrowing its advantage over the state from 13 points to 3. Science’s school average rose by 4 points, but the state rose by 7. SchoolDigger’s rankings also moved in different directions from 2023–24 to 2025–26: Millikin rose from percentile 44 to 60 and Northside from 47 to 56, while Southwest fell from 57 to 41. Millikin and Southwest have similar student–teacher ratios (13.4 and 13.6), and their 2024–25 free/reduced lunch eligible measures were 30% and 38%; these figures provide context, not an explanation for their different results.
