Summary

Decker Elementary is a K–6 school in Pomona, California, serving 437 students in Pomona Unified. In 2025–26, its proficiency rates were below both district and state averages in English language arts, math, and science. The most important takeaway is that the school’s test results are low across all three subjects, not just one.

Math is Decker’s strongest subject relative to the district and state, while science is its weakest compared with nearby K–6 schools. In 2025–26, Decker’s proficiency was 22% in math, 3 percentage points below the district and 16 below California; in ELA it was 31%, 7 points below the district and 18 below the state. Science proficiency was 19%, 4 points below the district and 17 below the state. Compared with averages of 43% in ELA, 32% in math, and 30% in science across nine nearby K–6 schools, Decker was behind by 11, 10, and 11 points, respectively. It ranked fourth-lowest locally in ELA and math, and second-lowest in science.

Results have declined from Decker’s 2022–23 levels: ELA fell 7 percentage points, math 4, and science 3, while California’s results rose in each subject. SchoolDigger placed Decker at the 22nd statewide percentile with 1 star in 2025–26, the fourth-lowest percentile among 11 nearby schools. Its 2024–25 student-teacher ratio was 19, the lowest among nearby schools with a reported ratio. Decker reported 76% free/reduced lunch eligible in 2024–25; that is context, not an explanation for its results. One notable exception to its overall ranking is special education: SchoolDigger placed Decker at the 64th statewide percentile for this group in 2025–26, compared with the 22nd percentile overall.
