Summary:
ZIP code 54436 in central Wisconsin is home to exactly one high school: Granton High, which serves grades 7 through 12 with 112 students and belongs to the Granton Area School District. Since there is only one school here, parents cannot compare local high school options against each other; the most useful comparison is how this school performs against Wisconsin averages and against its own past results. Roughly half of students (49.11%) qualify for free or reduced lunch, per-pupil spending is $18,584, and the student-teacher ratio is a relatively low 12.4 to 1.
The strongest parts of Granton High's profile are completion and attendance. The school reports a 100% graduation rate and a 0% dropout rate, both better than Wisconsin's 92% and 1.1%. Chronic absenteeism is 8.3%, less than half the state's 17.3%, though it is higher than the district's own 5.4%. Academically, 10th grade social studies is the clearest bright spot, scoring above the state in both reported years (54.55% vs. 48.25% in 2025–26, and 52.94% vs. 47.67% in 2024–25). Eighth grade science was above state in 2024–25 (54.55% vs. 50.04%) but fell to 30% in 2025–26, so it is not yet a stable strength.
Most other proficiency results fall below state averages, with mathematics the broadest concern: 8th grade math was 0% in 2024–25 and 10% in 2025–26 against a state rate near 53–54%, while 7th grade math was 25% and 33.33%. ACT ELA was notably low at 12.5% versus the state's 48.47%. The school's state ranking has also slipped, from the 47th percentile in 2022–23 to the 26th percentile in 2025–26, and the district ranks in the 7th percentile. With only 112 students, single-year percentages can shift sharply, so parents should watch multi-year trends; note too that 2024–25 test data includes 6th grade, outside the current 7–12 grade span.
