Summary:
ZIP code 54840 contains one elementary school, Grantsburg Elementary, a PK–3 building at 475 E James Ave, Grantsburg, WI, with 250 students in the Grantsburg School District. Since it is the only elementary school in the ZIP, there are no within-ZIP peer schools to compare; the useful comparisons are to its district and to Wisconsin statewide averages.
The school stands out for 3rd-grade Forward Exam proficiency that exceeds both its district and the state in every provided comparison. In 2025–2026, ELA was 78.57% proficient at the school, compared with 66.67% in the district and 52.08% statewide, while math was 75.00% at the school, 63.77% in the district, and 54.75% statewide. In 2024–2025, ELA was 75.44% at the school versus 66.67% in the district and 52.14% statewide, and math was 82.46% at the school versus 72.73% in the district and 55.00% statewide. ELA improved by 3.13 percentage points year over year, while math declined by 7.46 points but remained 20.25 points above the state. This is notable because the district ranks 302 of 432 in Wisconsin, at the 30th percentile with 2 stars, so the school’s 3rd-grade results are much stronger than the district-wide rating might suggest.
For 2024–2025, chronic absenteeism at the school was 12.0%, lower than the state’s 17.3% but higher than the district’s 6.0%. About 48.4% of students qualified for free/reduced lunch, per-student spending was $16,046, and the student-teacher ratio was 10.8:1. Because the school serves PK–3 and the test data cover only 3rd grade, these proficiency results should not be generalized to other grade levels.
