Summary:
ZIP code 91791 has six elementary schools: five serve K–5 and Wescove serves K–2; Wescove has no test results in the supplied data, so the achievement comparison covers the other five. Those five schools all scored above the state average in English language arts (ELA), four of five were above the state in math, and three of five were above in science. The most important takeaway is that schools’ results vary widely, especially in math and science.
Merced Elementary stands out in ELA and math, with 69% proficient in ELA and 71% in math—13 and 22 percentage points above the other four schools’ averages, respectively. Its results were also 20 points above the state in ELA and 33 points above in math. Mesa Elementary leads in science at 58%, 22 points above the state. At the other end, Workman Avenue Elementary is lowest in ELA (51%) and math (38%); its math result is 21 points below the other schools’ average and 1 point below the state. Vine Elementary has the lowest science result, 27%—17 points below the other schools’ average and 9 points below the state.
Recent changes are mixed: from 2024–25 to 2025–26, the five-school average rose by 1 point in ELA, was essentially unchanged in math, and fell by 3 points in science; the group’s science lead over the state narrowed from 11 points to 5. Workman’s ELA improved by 6 points, while science rose 15 points at Mesa but fell 15 at Grovecenter Elementary and 16 at Vine. SchoolDigger ranked Merced highest among these schools at the 88th percentile, followed by Mesa at the 82nd, Grovecenter at the 73rd, Vine at the 64th, and Workman at the 56th. The reported low-income measure is free/reduced lunch eligible for school year 2024–25: figures range from 54% at Mesa to 86% at Workman, while Merced is at 77% despite leading ELA and math; these are observations, not explanations of results. Merced’s student–teacher ratio is 29.3, compared with 21.3 at Vine, another difference that does not by itself explain performance.
