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. Results vary substantially from school to school: among regular high schools, the gap between the highest and lowest results is 38 points in ELA, 44 in math and 49 in science; among middle schools, it is 38, 37 and 34 points, respectively. The most important takeaway is that a family’s academic picture can look very different depending on the school and subject.

Eastlake High is the clearest regular high-school standout, with 82% proficiency in ELA, 56% in math and 72% in science—33, 18 and 36 points above the state rates. Its ELA result is 7 points above the next-highest regular high school, Otay Ranch Senior High; its science result leads Bonita Vista Senior High by 22 points. At the lower end, San Ysidro High has the lowest regular-high-school ELA and science results, at 44% and 22%; Chula Vista Senior High has the lowest math result, at 12%. Among middle schools, Rancho del Rey Middle leads in ELA at 68%, while Eastlake Middle leads in math and science at 52% and 46%. Castle Park Middle has the lowest ELA and science results; Mar Vista Academy has the lowest math result.

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.
