Summary:
Zip code 61030 has three schools serving preschool through grade 12 in Forrestville Valley CUSD 221, with 714 students combined. Two schools have reported test results; German Valley Grade School has 70 students but no test scores supplied. The broad picture is encouraging, especially in elementary math, but the most important exception is Forreston Junior/Senior High School’s low 10th-grade PreACT results in ELA and science.
Forreston Grade School stands out in the reported 2025–26 all-grades IAR results: 69% in ELA and 64% in math, compared with 56% and 40% statewide. The high school also exceeds state results, at 64% in ELA and 46% in math. The schools’ all-grades results differ by about 5 points in ELA and 18 in math, but they serve different grade spans, so those are not same-grade comparisons. The elementary school’s strongest results are in fifth grade: ELA is 31 points above the state, math 31 points above, and science 36 points above. The high school’s clearest weakness is 10th-grade PreACT: ELA is 25 points below the state and science 23 points below; math is 4 points below.
Recent IAR trends favor the high school: from 2024–25 to 2025–26, its ELA rose from 61% to 64% and math from 44% to 46%, while the state also improved. The elementary school’s ELA was nearly flat, moving from 70% to 69%, and math fell from 67% to 64%; its lead over the state narrowed by about 4 points in ELA and 5 in math. SchoolDigger ranks the high school at the 46th percentile in both recent years, while the elementary school is at the 81st percentile, down from the 87th. As context, 2024–25 free/reduced lunch eligible shares were 41% at the high school, 40% at the elementary school, and 29% at German Valley; student-teacher ratios were 15.3, 11, and 14.1, respectively. These figures provide context, not an explanation for achievement differences.
