Summary:
The Port Washington-Saukville School District serves about 2,415 students across five schools in Ozaukee County, Wisconsin — three elementary schools (PK–4), one middle school (5–8), and one high school (9–12). It is a 4-star district ranked 51st of 432 Wisconsin districts (88th percentile), and every school in the district scores above the state average in essentially every subject tested over the past two years.
Among the elementaries, Dunwiddie Elementary is the strongest, holding 5 stars in each of the last two years and ranked 74th of 1,039 statewide, with the district's biggest average margin over state (+22.7 points). Thomas Jefferson Middle is steady at 4 stars, highlighted by an 8th-grade social studies jump of 12.2 points, though 6th grade is the district's tightest spot — its margins over state are roughly a quarter the size of any other grade. Port Washington High is a top-50 Wisconsin high school (43rd of 533) with a 95.8% graduation rate and 0.5% dropout rate, but it also has the district's highest chronic absenteeism at 15.4%. Saukville Elementary has climbed three years running (445th to 217th), while Lincoln Elementary has slipped three years running (82nd to 198th) despite posting the district's lowest absenteeism at 4.5%.
Two patterns matter for families choosing a school. First, money and poverty don't predict results here: elementary spending sits within about $860 per pupil, yet proficiency margins range from +15.3 to +22.7, and Dunwiddie achieves the best outcomes with the highest poverty indicator (32.7%). Second, 4th-grade science is the widest-spread subject — 54.00 at Saukville to 81.36 at Dunwiddie, a 27.4-point gap. The one clear warning sign is high school math, down 5.89 points year over year.
