Summary:
Johnston’s seven public schools serve 2,984 students from early childhood through grade 12: five elementary schools, one middle school and one high school. The schools are in Johnston, Rhode Island, and reported student–teacher ratios range from 10.3 to 12.2. The clearest area-wide concern is that elementary proficiency averages trail state rates by roughly 9 to 11 percentage points, although middle-school English language arts is nearly at the state level.
Brown Avenue School leads elementary English language arts at 27.5%, while Thornton School leads math at 30.0% and science at 27.6%; Brown is close behind in math at 29.7%. At the other end, Winsor Hill School has the lowest elementary English language arts result, 19.4%, and Sarah Dyer Barnes School has the lowest math result, 12.2%—17.8 points below Thornton. Nicholas A. Ferri Middle is close to the state in English language arts (33.0% versus 33.1%), but trails by 12.6 points in math. Johnston Senior High has a 94.0% graduation rate, above the district’s 93.0% and state’s 85.5%, despite below-state results on its supplied tests.
Recent results are mixed, with elementary averages falling from 2024–2025 to 2025–2026 by 3.9 points in English language arts, 7.9 in math and 2.3 in science; Thornton and Brown are close in current math, but Brown’s rate dropped 17.7 points year over year. Barnes also had the sharpest reported SchoolDigger statewide percentile decline among these schools, from 32 to 13; Brown fell from 56 to 37. Income measures do not neatly track results: Thornton has the highest reported free/reduced-lunch rate among tested elementary schools, 68.82%, while leading in math and science, whereas Brown has the lowest rate, 43.03%, and leads in English language arts. These figures are context, not an explanation for school results.
