Summary:
Zip code 94568 has nine elementary schools serving grades K–5 or K–8; eight are in Dublin Unified, and one is in a separate district. In 2025–26, the eight Dublin schools averaged 78% in ELA, 79% in math and 66% in science, compared with California averages of 49%, 38% and 36%. Those strong area averages mask a meaningful difference between schools: the most important finding is that results vary widely, including among schools serving the same grades.
Harold William Kolb led the eight schools in all three subjects, with 87% in ELA, 88% in math and 77% in science. Frederiksen Elementary had the lowest results: 62% in ELA, 59% in math and 54% in science. The gaps between them were 25, 29 and 23 percentage points, respectively. Same-grade comparisons reinforce the contrast: in Grade 3 ELA, Kolb scored 92% and Frederiksen 54%; in Grade 4 math, J. M. Amador Elementary led at 89%, while Frederiksen had 56%. Cottonwood Creek also stands out, with scores of 84% in ELA, 84% in math and 69% in science, and the area’s lowest chronic absenteeism at 7%.
Recent changes were mixed rather than a uniform rise or fall: the eight-school average was nearly unchanged in ELA and math from 2024–25, while science fell 2 percentage points. Murray Elementary improved by 4 points in ELA and 5 in math; J. M. Amador Elementary fell 5 points in ELA, 4 in math and 15 in science. SchoolDigger ranked Kolb 49th of 5,804 statewide and Frederiksen 1,118th. Student-teacher ratios among the eight schools ranged from 21.6 at Murray to 26.1 at Kolb, without matching a simple pattern in scores. The reported measure for all nine schools is free/reduced lunch eligible (2024–25): among the Dublin schools, it ranged from 7% at Amador to 25% at Frederiksen; Knowledge Enlightens You (KEY) Academy reported 82%. KEY’s latest scores are from 2024–25, so it is not included in the current-year comparisons.
