Summary

Sandburg Middle in Glendora, California, serves grades 6–8 and enrolls 695 students in an area with several nearby middle-school options. The most important finding is that its 2025–26 test results were above California’s average in English language arts (ELA), math and science, but below Glendora Unified in all three subjects.

ELA is Sandburg’s strongest result relative to the state, while science is closest to the state average; math has the largest gap with the district. Sandburg had 58% proficient in ELA, compared with 49% statewide and 61% districtwide; in math, it had 43%, versus 38% statewide and 52% districtwide. Science results were 37%, compared with 36% statewide and 40% districtwide. Against nearby schools serving grades 6–8, Sandburg is in the middle: fourth of nine in ELA and fifth in math and science. Its ELA result is close to the peer average, while its math and science results are below those averages.

Results have improved over the longer term, but the state comparison has shifted by subject: Sandburg’s ELA lead over California widened from 6 to 8 points between 2022–23 and 2025–26, while its math lead narrowed from 6 to 5 points and its science lead from 4 to 1. Math and science also dipped in the latest year. SchoolDigger ranks Sandburg at the 72nd percentile statewide and gives it four stars; its recent percentile has stayed between 70 and 73, below its 82nd-percentile peak in 2015–16. SchoolDigger’s effectiveness ranking for “Low Socio Economic Status Students” rose from the 48th to the 64th percentile from 2024–25 to 2025–26.
