Summary:

Reed Union Elementary has three schools serving kindergarten through grade 8: Reed Elementary (K–2), Bel Aire Elementary (grades 3–5), and Del Mar Middle (grades 6–8). Together, they enroll 1,043 students. Test scores are available for Bel Aire and Del Mar, but not Reed. The strongest overall finding is that both tested schools scored above state results in all three subjects in 2025–26, with school-to-state gaps ranging from 30 to 43 points.

Del Mar Middle stands out in English language arts and science: it scored 82% in ELA, 3 points above Bel Aire, and 79% in science, 13 points above Bel Aire. Bel Aire Elementary narrowly led in mathematics, scoring 79%, 1 point higher than Del Mar. Attendance offers another distinction: Reed Elementary had the lowest chronic absenteeism rate, at 6%, while Del Mar had the highest, at 11%; Bel Aire was at 7%. Del Mar’s rate was below the state’s 18%, but above the district’s 8%.

Recent score trends differ: from 2024–25 to 2025–26, Bel Aire rose 1 point in ELA, 3 in math, and 2 in science; Del Mar fell 2 points in ELA and 3 in math, while rising 7 points in science. SchoolDigger’s percentile ranking for Bel Aire increased from 91 to 96 across the three reported years; Del Mar’s went from 96 to 98, then 97. In 2024–25, student–teacher ratios were 17.7 at Bel Aire and 11.6 at Del Mar. Their reported free/reduced lunch eligible (FRL) figures for 2024–25 were 8% and 5%, respectively; Reed’s was 3%. These measures provide context, not an explanation for score differences. All-grades scores compare schools with different grade spans, and Reed has no test scores supplied.
