Both elementary schools outperform the state overall, but they differ in subject strengths: Lincoln is slightly stronger in ELA, while Dunwiddie is substantially stronger in math, social studies, and science.

At the middle and high school levels, Thomas Jefferson Middle ranks in the 78th percentile with 4 stars, up from 73rd, and has the lowest student-teacher ratio at 12.2. Its 8th grade social studies and science results are strong, though 6th grade ELA and math have narrower margins over state. Port Washington High is a 5-star, 92nd-percentile school with a 95.8% graduation rate and a 0.5% dropout rate, both better than state.

Recent math and science results declined, while social studies improved. All Port Washington scores exceed state averages, with Dunwiddie Elementary and Port Washington High the clearest standouts, Thomas Jefferson Middle improving, and Lincoln Elementary still above state despite a declining rank.
