Summary:
Zip code 91024 has one middle school, Sierra Madre Middle, serving grades 6–8 and enrolling 597 students. Its 2025–26 proficiency rates were above California’s in all three reported subjects: 67% in English language arts (ELA), 58% in math and 50% in science. The most important finding is that the school remains well ahead of state results, with its largest lead in math.
Since the list contains only one school, there is no within-zip-code top or bottom comparison. Against the state, Sierra Madre Middle was ahead by 18 percentage points in ELA, 20 in math and 14 in science; it also exceeded Pasadena Unified by 20, 21 and 14 points, respectively. Grade-level results were above state rates in all six reported subject-and-grade comparisons. Grade 8 ELA is the relative weak spot: 56% of students were proficient, a 6-point lead over the state, compared with leads of 21 points in grade 7 ELA and 25 points in grade 7 math.
The school’s proficiency rates fell from 2024–25 to 2025–26, while state rates rose or changed little, narrowing the school’s advantage by 2 points in ELA, 2 in math and 9 in science. Science had the sharpest school decline, down 5 points, while its state rate rose 3 points. SchoolDigger still gives the school four stars and ranks it at the 86th percentile statewide, down 4 percentile points from 2023–24. Other context includes a 23.5 student–teacher ratio in 2024–25 and 39% free/reduced lunch eligible that year; these figures describe the school but do not establish why results differ or change.
