San Diego County has 764 public schools serving a population of 3.29 million, making it the second-largest school county in California by school count. The county's school landscape runs from some of the highest-scoring public high schools in the state to schools performing well below the California average of 47.1% reading proficiency. For families making housing decisions in the San Diego metro, the score data across specific schools and districts tells a clearer story than neighborhood reputation alone.
This breakdown organizes metro San Diego's public high schools by test score performance on state reading assessments, with district context, enrollment, and rent data for each corridor. All proficiency figures are from SY 2024-25 California state assessment data available on each school's scores page.
The Top Tier: Schools Above 80% Reading Proficiency
Five public high schools in San Diego County post reading proficiency rates above 80%, placing them among the strongest large public high schools in Southern California and well above the state average.
Canyon Crest Academy in San Diego leads the county at 91.9% reading proficiency with 2,183 students enrolled. The Canyon Crest Academy scores page shows multi-year consistency at this level, driven by the school's position in the affluent Carmel Valley neighborhood and its dual-enrollment partnership with UC San Diego. Canyon Crest operates as a choice school within San Dieguito Union High School District, meaning students from outside the immediate attendance zone can apply, though demand is high and access competitive.
Westview High School in the Rancho Penasquitos area posts 92.0% reading proficiency with 2,186 students, just above Canyon Crest. Westview sits within Poway Unified School District, which serves 34,755 students across 39 schools. The Westview High scores page reflects the demographics of Rancho Penasquitos, one of the more affluent master-planned communities in North San Diego, with a high concentration of technology and biotech workers from the Sorrento Valley and Torrey Pines science corridors.
Scripps Ranch High School in the Scripps Ranch community posts 84.2% reading proficiency with 1,920 students, also within Poway Unified. Scripps Ranch has built a strong academic reputation over three decades as one of San Diego's most family-oriented planned communities, and the school consistently performs among the top campuses in the district.
Del Norte High School in the 4S Ranch area of Poway Unified posts 83.2% reading proficiency with 2,564 students. Del Norte serves the newer development in the northeastern part of the district and has quickly established itself alongside Westview as one of Poway Unified's top two academic performers. The Del Norte High scores page shows the upward trajectory of a school whose demographics have solidified as the surrounding community has matured.
Sage Creek High School in Carlsbad posts 84.2% reading proficiency with 1,358 students, making it the smaller but academically competitive counterpart to Carlsbad High within Carlsbad Unified School District. Sage Creek opened in 2013 as a STEM-focused campus and has developed a strong academic culture in a relatively short time. The Sage Creek scores page shows consistent performance above 80% across multiple years.
Torrey Pines High School in Del Mar posts 81.6% reading proficiency with 2,644 students, the largest campus in San Dieguito Union High School District. Torrey Pines is one of the most recognized high schools in San Diego County, combining strong academics with one of the better-known athletics programs in Southern California. The school's attendance zone covers Del Mar and the western portion of Carmel Valley, keeping its demographic profile consistently high-income. The Torrey Pines High scores page reflects decades of sustained academic investment.
Eastlake High School in Chula Vista is the notable outlier in this tier, posting 83.2% reading proficiency within Sweetwater Union High School District, a district whose overall profile is significantly below the county average. Eastlake serves the newer, more affluent development in eastern Chula Vista and its performance reflects the demographic divergence between that part of the district and the district's National City and western Chula Vista campuses. The Eastlake High scores page makes this contrast visible against the district average.
The Strong Tier: 70% to 80% Reading Proficiency
A second cluster of San Diego County high schools posts reading proficiency between 70% and 80%, still well above the state average and representing strong academic environments across multiple corridors of the county.
Rancho Bernardo High School in Poway Unified posts 79.4% proficiency with 2,278 students, rounding out a district whose four main high school campuses all perform in the top quartile of San Diego County. Rancho Bernardo has a long-established reputation as one of North San Diego's premier communities, and the high school reflects the sustained community investment that has characterized the area since its development in the 1970s and 80s.
Mt. Carmel High School in the Sabre Springs and Rancho Penasquitos area of Poway Unified posts 74.0% proficiency with 1,831 students. Mt. Carmel has a strong fine arts and performing arts program alongside solid academic performance, making it a notable option for families whose students have interests beyond pure academic metrics.
Otay Ranch Senior High School in Chula Vista posts 70.3% proficiency with 2,546 students within Sweetwater Union. Like Eastlake, Otay Ranch serves the newer eastern Chula Vista development and performs dramatically above the district average, representing the school quality available in this corridor for families who do their research rather than making assumptions based on the district name.
Bonita Vista Senior High in Chula Vista posts 70.7% proficiency with 2,049 students, also within Sweetwater Union. Bonita Vista serves the older, more established western Chula Vista neighborhoods and has maintained solid performance despite serving a more economically diverse student population than Eastlake or Otay Ranch.
Olympian High School in Chula Vista posts 78.4% proficiency, one of the stronger scores in the county, reflecting the newer development it serves in the eastern Chula Vista corridor.
San Dieguito Union High's other campuses fill out this tier. San Dieguito High School Academy in Encinitas posts 71.4% proficiency with 1,954 students. The school has a distinctive project-based learning culture and significant choice enrollment from outside its immediate zone. La Costa Canyon High School in Encinitas posts 69.7% proficiency with 1,768 students, serving the inland Encinitas and La Costa communities with consistent performance above state averages.
The Middle Tier: Near or Somewhat Above State Average
Carlsbad High School within Carlsbad Unified posts 67.8% proficiency, strong in absolute terms but below its newer sibling Sage Creek, reflecting the broader demographic profile of older Carlsbad versus the newer eastern development that Sage Creek serves.
Valhalla High School in El Cajon posts 67.5% proficiency, one of the stronger results in the East County corridor where most schools perform closer to or below state averages. San Marcos High School posts 53.2% and Mission Hills High School 56.1%, both above state average and reflecting the mixed but improving demographic profile of the San Marcos corridor in North County inland.
El Camino High School in Oceanside Unified posts 47.9% proficiency, near the state average in a district serving 15,274 students where the economic profile of the student population is more mixed than the coastal location might suggest.
The Lower Tier: Below State Average
San Diego Unified, the county's largest district serving the urban core of the city, has significant variation between its campuses. Madison High School in the Linda Vista neighborhood posts 39.9% proficiency, below the state average and reflecting the economic and demographic profile of the communities it serves. Several other San Diego Unified campuses serving lower-income neighborhoods perform in similar or lower ranges.
Sweetwater Union's campuses serving National City and western Chula Vista neighborhoods perform well below the district's eastern campuses. The contrast between Eastlake at 83.2% and National City campuses at a fraction of that figure within the same district illustrates how misleading district-level averages can be for families trying to understand what specific schools actually provide.
The Poway Unified Story: The County's Most Consistently Strong Large District
Poway Unified deserves specific attention as the strongest large district in San Diego County. The district serves 34,755 students across 39 schools in Poway and the North San Diego communities of Rancho Bernardo, Rancho Penasquitos, Scripps Ranch, 4S Ranch, and Sabre Springs. Its five high school campuses, Westview, Del Norte, Scripps Ranch, Rancho Bernardo, and Poway High, all post proficiency rates between 62.6% and 92.0%, giving the district a floor well above the state average even at its lowest-performing campus.
The geographic spread of the district across multiple planned communities in North San Diego creates a situation where most of the housing in the district's footprint produces strong school placements. Unlike Orange County's Sweetwater or San Diego Unified, where address selection within the district boundaries determines whether a family lands at a top or bottom-quartile school, Poway Unified's range is narrow enough that most addresses within it produce an outcome families would consider strong.
Rent in the Poway Unified footprint varies by community. Poway itself is one of the more affordable cities in the district. The Carmel Valley and Rancho Penasquitos communities within the district carry higher rent that reflects both school demand and the communities' proximity to the Sorrento Valley tech corridor.
San Dieguito Union High: The Coastal North County Premium
San Dieguito Union High School District serves 12,341 students across 10 schools in the coastal North County communities of Del Mar, Carmel Valley, Encinitas, and Solana Beach. The district's four main high schools, Torrey Pines, Canyon Crest Academy, San Dieguito High School Academy, and La Costa Canyon, all post proficiency rates between 69.7% and 92.0%.
The district's small size and coastal location produce some of the highest rents in San Diego County. Del Mar, which feeds into Torrey Pines High, has some of the most expensive housing in the region. Encinitas, feeding into La Costa Canyon and San Dieguito Academy, is more accessible but still carries a coastal premium. Families who want this district specifically should expect to pay accordingly. Del Mar rent is among the highest in the county.
The Sweetwater Surprise: Chula Vista's Eastern Corridor
Sweetwater Union High School District's overall reputation understates what's available in its eastern Chula Vista attendance zones. The district serves 34,445 students across 29 schools, and its district-wide average is pulled down significantly by the National City and western San Diego campuses. Families who look at Sweetwater Union as a district and dismiss it miss that Eastlake High at 83.2% and Olympian High at 78.4% are within that same district, accessible from eastern Chula Vista addresses at rent levels meaningfully lower than comparable school quality would cost in Poway or North County coastal communities.
Chula Vista rent is among the more affordable options in San Diego County for families who want strong schools. The key is verifying the specific high school attendance zone before committing to an address, since the difference between an Eastlake zone and a Sweetwater High zone within the same city is the difference between 83% and roughly 40% proficiency.
Carlsbad Unified: Two High Schools, Two Different Profiles
Carlsbad Unified serves 10,795 students across 16 schools entirely within the city of Carlsbad. The district's two high schools tell different stories. Sage Creek High at 84.2% serves the newer eastern development and has a STEM-focused culture with strong college preparation. Carlsbad High at 67.8% serves the older, more established coastal and central Carlsbad neighborhoods and still performs well above state averages despite a slightly more diverse economic profile than Sage Creek's attendance zone.
Carlsbad is one of the few cities in San Diego County where a family can get above-state-average schools from both high school campuses regardless of which attendance zone they land in. The city's overall school quality is high enough that address selection within Carlsbad is a secondary concern compared to the choice between Carlsbad and lower-performing surrounding cities. Carlsbad rent is lower than Del Mar or Carmel Valley and represents one of the better overall value propositions in the North County coastal corridor for families focused on school quality.
How to Find Your School's Scores Before You Sign a Lease
Every public school in San Diego County has a scores page on allk12 at the school's URL plus /scores, showing four-year reading proficiency history with grade-level breakdowns and comparisons against state, district, and county averages. The scores pages for Westview High, Canyon Crest Academy, Del Norte High, Torrey Pines High, Scripps Ranch High, Eastlake High, and Sage Creek High give the clearest picture of sustained performance at the county's top schools.
For any address you're considering, verify the specific high school attendance zone directly with the district rather than relying on neighborhood reputation or a landlord's description. Attendance zones in growing parts of the county, particularly eastern Chula Vista and parts of the Carlsbad-San Marcos corridor, have been redrawn as new schools have opened, and a zone that was accurate eighteen months ago may have changed.
