Summary:
Zip code 95524 has one listed school, Jacoby Creek, serving kindergarten through 8th grade and enrolling 455 students. With no other listed schools, families are comparing this school with California’s results and looking at differences between grades, rather than choosing among local schools. The clearest overall finding is that Jacoby Creek’s 2025–26 proficiency was above the state in every reported subject: about 77% in English language arts (ELA), 66% in math, and 61% in science, compared with 49%, 38%, and 36% statewide.
Jacoby Creek is both the highest- and lowest-performing school in this list by default, so that does not indicate a lead over local peers. Its advantage over California was about 28 percentage points in ELA, 28 points in math, and 25 points in science. Results also varied by grade, especially in math: proficiency ranged from 46% in 6th grade to 81% in 7th, a 35-point spread. Both were above their same-grade state results, but by about 9 points in 6th grade and 43 points in 7th. ELA ranged from 63% in 3rd grade to 83% in 5th and 8th; science ranged from 52% in 8th grade to 70% in 5th.
All-grade results improved slightly from 2024–25 to 2025–26: ELA rose about 1 point, math about 1 point, and science by less than 1 point. California also improved, so the school’s advantage widened by about 1 point in ELA, stayed essentially unchanged in math, and narrowed by about 3 points in science. SchoolDigger ranked Jacoby Creek in the 87th percentile in both 2024–25 (785 of 5,857) and 2025–26 (781 of 5,804), down from the 90th percentile in 2023–24 (614 of 5,869); those rankings offer a different comparison from the subject scores. As context, the student–teacher ratio was 20.5 in 2024–25, and 35% of students were reported as free/reduced lunch eligible in 2024–25. These figures describe the school but do not establish what explains its results. Since this ZIP code has only one listed school, the data cannot show how Jacoby Creek compares with local peers.
