Summary

La Tercera Elementary is a 295-student K–6 school in Petaluma, part of the Old Adobe Union district. Its clearest strength is English language arts (ELA), while math is the main area to watch in comparison with its district. Most important, in 2025–26 La Tercera scored above the California average in all three reported subjects: ELA, math, and science.

Compared with the state, La Tercera was ahead by 9 percentage points in ELA, 6 in math, and 6 in science. Its district comparison is more mixed: ELA was 4 points above the district, while math was 5 points below and science 1 point below. Against nearby schools with 2025–26 results, La Tercera ranked 4th of 9 in ELA and 5th of 9 in both math and science. Its scores were 9 points above the nearby-school average in ELA and 5 points above in science, but 5 points below the average in math. This makes math the clearest relative weakness, despite being above the state average.

Results have improved substantially: from 2022–23 to 2025–26, ELA rose from 30% to 58%, math from 30% to 44%, and science from 22% to 42%. Over that period, the school’s gap against the state improved by 25 points in ELA, 10 in math, and 14 in science. SchoolDigger rates La Tercera at the 69th percentile and 3 stars, up from the 39th percentile and 2 stars in 2022–23; its nearby standing is 4th of 9 schools with a current rank. The 2024–25 student-teacher ratio was 23.6, near the middle of the nearby range. SchoolDigger’s statewide effectiveness percentile for White students rose 27 points, from 26 to 53, but remains below the school’s overall 69; the percentile for Hispanic students is 52. These are measures of how well SchoolDigger ranks the school in serving those groups.
