Summary:
Calvin Elementary School (PK–8, 126 students) and Calvin High School (grades 9–12, 42 students) are Calvin’s two listed schools, serving 168 students across PK–12. The schools report results in English Language Arts I and mathematics, while science and U.S. History results are reported for the high school. The clearest recent bright spot is Elementary’s 2025–2026 mathematics result: 44% proficient, 19 points above the state’s 25%.
Elementary stands out in mathematics, while High School’s reported proficiency is below the state in every subject. Elementary’s math result rose 19 points from the previous year; its ELA result was 25%, just 1 point below the state. High School’s 2025–2026 all-grades results were 19% in ELA, 6% in mathematics, 6% in science, and 31% in U.S. History—respectively 7, 19, 24, and 10 points below the state. Science was its largest shortfall. Its 11th-grade results were also below state results in all four subjects. Because the schools serve different grade spans, their all-grades results are not direct same-grade comparisons.
Recent trends differ by school: Elementary’s math gap versus the state shifted from 1 point below in 2024–2025 to 19 points above in 2025–2026, while its ELA gap stayed 1 point below. High School’s average gap across its four reported subjects widened from 14 to 15 points below the state. SchoolDigger rankings offer longer-term context: High School was at the 85th percentile in 2014–2015, versus the 11th in 2025–2026; Elementary’s listed ranking went from the 57th percentile in 2009–2010 to the 15th in 2014–2015. In 2024–2025, student-teacher ratios were similar—10.1 at Elementary and 9.3 at High School—while free/reduced lunch eligible rates were 77% and 91%, respectively. These are contextual measures, not explanations for results. High School’s 2024–2025 graduation rate was 88%, 10 points above the state; both schools also had lower chronic absenteeism than the state in 2025–2026.
