Summary:

Dublin, California, has 15 schools—8 elementary, 2 middle, 4 high, and 1 alternative—serving students from elementary through high school, including specialized programs. Of the 13 schools with reported 2025–26 all-grades scores, unweighted averages were 74% in ELA, 70% in math, and 59% in science, compared with California’s 49%, 38%, and 36%. York Alternative Learning Center’s test figures are suppressed, while Dublin Unified Transition Program has no test-score entries. The main takeaway is that Dublin’s averages are well above state results—by 25 points in ELA, 31 in math, and 23 in science—but school results vary widely, with ranges of 59, 88, and 65 points, respectively.

Harold William Kolb leads all three subjects, with 87% in ELA, 88% in math, and 77% in science; SchoolDigger ranks it 49th of 5,804 elementary schools, in the 99th percentile. At the other end, Valley High (Continuation) scored 29% in ELA, 0% in math, and 12% in science. Among middle schools, Eleanor Murray Fallon leads Wells Middle by 16 points in ELA, 19 in math, and 40 in science. Among the comprehensive high schools, Emerald High leads Dublin High in 11th grade by 8 points in ELA, 7 in math, and 12 in science. Frederiksen Elementary has the lowest scores among the K–5 schools, but remains above state results in all three subjects.

Year-to-year results are mixed: across 12 schools with scores in both years, average ELA rose 1 point, math was essentially unchanged, and science fell 2 points, while state science scores rose 3 points. Kolb improved in every subject—by 4 points in ELA, 2 in math, and 10 in science—while J. M. Amador Elementary fell by 5, 4, and 15 points. Valley’s 20-point ELA gain drove the group’s increase; without it, the other schools’ average was essentially flat. Other measures also do not sort schools neatly: among K–5 schools, Kolb has the highest student–teacher ratio at 26.1, while Murray Elementary has the lowest at 21.6. In 2024–25, free/reduced lunch eligible figures were 15% at Kolb and 25% at Frederiksen, yet Kolb scored higher in all three subjects.
