Summary:
Zip code 54162 is home to exactly one elementary school: Glenbrook Elementary, a PK–5 building at 145 W Green Bay St in Pulaski, Wisconsin, serving 519 students as part of the Pulaski Community School District. Because Glenbrook is the only elementary school in the zip, there is no in-town peer to compare it with — the useful comparisons are against its own district and against the state of Wisconsin.
The school's standout strength is attendance. Its chronic absenteeism rate of 6.8% is far lower than the district's 11.4% and the state's 17.3%, and it is the only measure where Glenbrook clearly outperforms both. Fifth grade is another bright spot: Math 5 reached 72.62% proficient in 2024–2025 — 20 points above the state and the highest single score in the data set — and ELA 5 has run 9 to 12 points above the state in both years. Overall, Glenbrook beat the state average in 12 of 16 grade-subject-year records.
The concerns are real, though. Glenbrook trails its own high-performing district in 13 of 16 records, and in 2025–2026 it trails the district in every subject and grade. Its state rank slipped from the 74th percentile (4 stars) in 2023–2024 to the 60th, then the 55th (3 stars) in 2025–2026. Science is the clearest weak point — the only subject where it scored below the state in 2025–2026 (49.33% vs. 53.46%) — and Grade 4 posted the school's lowest reading and science results. For context, 28.9% of students qualify for free or reduced lunch, per-student spending is $17,066, and the student-teacher ratio is 10.7 to 1. In short: a mid-pack school inside a strong district, with excellent attendance, a strong fifth grade, and room to grow in science and fourth grade.
