Summary:
ZIP code 57301 includes eight schools in Mitchell School District 17-2: five elementary schools, one middle school and two high schools, serving students from elementary through high school. The clearest academic standout among the conventional elementary schools is Longfellow Elementary: in 2025–26, 57% of students were proficient in ELA and 63% in math, compared with state results of 49% and 44%. Its math result was 19 percentage points above the state, making Longfellow the strongest overall elementary choice in the reported results.
Mitchell Middle School also stands out, with ELA and math results 9 and 6 points above the state, plus eighth-grade science 5 points above. Among the K–5 schools, L. B. Williams Elementary and Gertie Belle Rogers Elementary are closer to one another, though L. B. Williams is ahead in 2025–26 All Grades ELA and math. Rosedale Colony Elementary is the low outlier: its results were 33% in ELA and 13% in math, respectively 16 and 30 points below the state. At Mitchell High School, 11th-grade ACT ELA and science were above the state, while math was slightly below. Abbott House Elementary had sharply mixed eighth-grade results in 2024–25—100% in ELA and science, but 0% in math—among just 13 students. Because grade spans and, for Mitchell High, the test differ, these figures are not a single like-for-like ranking; Abbott House High School has no school test results in the supplied data.
Results improved unevenly over time: Longfellow’s ELA rose 9 points from 2024–25 to 2025–26, while Rosedale’s fell 13 points; across five schools with comparable results, the average ELA result rose 1 point and math fell 2 points. SchoolDigger gives Longfellow four stars and places it at the 71st percentile. It also had the lowest reported chronic absenteeism among the larger schools, at 6%, versus 16% districtwide and 20% statewide. Among the three K–5 schools, Longfellow’s 2024–25 free/reduced lunch eligible share was 46%, compared with 41% at each of the other two; its student-teacher ratio was 9.6, versus 12 at L. B. Williams and 13.7 at Gertie Belle Rogers. These are useful points of comparison, not explanations for student results.
