Summary:
Sweetwater Union High includes 28 schools—17 high schools and 11 middle schools—with programs serving middle- and high-school grades, as well as some wider-grade-span or alternative programs.

The most important takeaway is that a family’s academic picture can look very different depending on the school and subject.

Recent changes differ by grade group: regular high-school averages fell 1 point in ELA, rose 1 in math and 7 in science from the prior year, while middle-school averages rose 1, 2 and 3 points, respectively. SchoolDigger’s own ratings also vary: Eastlake High received 5 stars in 2025–26, compared with 1 star for Palomar High. Results can also differ by subject within a school: Mar Vista Senior High had 62% ELA proficiency but 17% in math. It falls within a group of regular high schools where 76.9%–84.4% of students were reported as free/reduced lunch eligible in 2024–25, a useful context measure but not an explanation for scores. Alternative programs also have distinct profiles: Launch Virtual Academy had 50% ELA and 41% math proficiency, alongside 70% chronic absenteeism.
