Summary

South Elementary School is a K–5 school in Crystal Lake, Illinois, serving 390 students in Crystal Lake CCSD 47. Its latest results show strong performance in both English Language Arts (ELA) and math: 69% of students were proficient in ELA and 58% in math. The most important finding is that the school ranks among the very best nearby in both subjects and leads the other schools in its district.

In all-grades ELA and math, the school ranks second among 11 nearby schools, including itself, behind Lincoln Prairie Elementary School. ELA proficiency is 7 percentage points above the district and 13 above the state; math is 14 points above the district and 19 above the state. Fifth-grade ELA is an especially clear strength: 79% proficiency is the highest among nearby schools, ahead of Lincoln Prairie at 71%. Math varies more by grade: fourth-grade proficiency is 64%, compared with 53% in fifth grade, though fifth-grade math still ranks second locally. Third-grade math is 58%, around the middle of nearby results.

Scores have risen over time: from 2023–2024 to 2025–2026, ELA increased 17 percentage points and math 18 points. The school’s advantage over state results widened over that period, though its math lead narrowed slightly in the latest year. SchoolDigger gives the school a 74th-percentile statewide ranking and four stars for 2025–2026, down from the 79th and 80th percentiles in the prior two years, but still second among nearby schools. Its 2024–2025 student–teacher ratio was 10.9, the second lowest among nearby schools; 27% of students were free/reduced lunch eligible that year. SchoolDigger’s statewide effectiveness ranking for Low Socio Economic Status Students rose from the 51st percentile in 2022–2023 to the 88th in 2024–2025, above the school’s overall 80th-percentile ranking that year. Its ranking for Special Education Students fell from the 69th percentile in 2023–2024 to the 48th in 2024–2025, while the overall ranking was 80th; these are rankings of how well the school serves groups, not measures of the students themselves.
