IUSD Ranks No. 1 in California Again — Why a Decade at the Top Still Matters for Great Park & Portola Springs Values

The short version: On 2026 state test results, Irvine Unified School District ranked No. 1 in California in math, science and English language arts among districts with 35,000 or more students. It's the 10th year in a row that IUSD has ranked among the top-performing districts in both the state and Orange County. For homes in Great Park and Portola Springs, that consistency is a big part of why buyers keep choosing addresses inside IUSD boundaries.

Every fall, when CAASPP results come out, I get the same text from past clients: "Did we hold the top spot?" This year IUSD did. The district announced the 2026 results on October 15. The headline is nice, but the numbers underneath it are what I'd look at if I were buying.

What the 2026 IUSD Ranking Actually Says

CAASPP, the California Assessment of Student Performance and Progress, is the state's standardized test. Students in grades 3 through 8 and grade 11 take the math and ELA tests, and science is tested in grades 5, 8 and once in high school. Here's how IUSD compared in 2026, using the percentage of students who met or exceeded the standard:

• Math: IUSD 71%, Orange County 50%, California 38%
• Science: IUSD 65%, Orange County 46%, California 36%
• English language arts: IUSD 74%, Orange County 59%, California 49%

That puts IUSD 32 points above the state in math, 29 in science and 25 in ELA. The district serves more than 36,000 TK-12 students, so it's competing with California's largest districts, not a handful of small ones.

One accuracy note. The "10th consecutive year" refers to IUSD ranking among the top-performing districts in the state and county since CAASPP launched. In recent years that has meant No. 1 in its size category, including in 2025. Earlier years in the run included No. 2 finishes. A decade at or near the top is the real story, and it's an impressive one.

Which IUSD Schools Serve Great Park and Portola Springs?

The newer villages have some of the newest schools in the district, many of them built alongside the neighborhoods:

• Great Park Neighborhoods: Beacon Park K-8 (opened 2016), Cadence Park K-8 (2018) and Solis Park K-8 (2022), according to IUSD's facilities records.
• Portola Springs: Portola Springs Elementary and Loma Ridge Elementary, which opened in 2019.
• High school: Portola High School opened in 2016 within Great Park Neighborhoods. It serves Great Park, Portola Springs and nearby communities.

Attendance boundaries change as new tracts open, and a specific address can be zoned differently than the school down the street. I always tell buyers to confirm the assignment for the exact address with IUSD before they write an offer. I walk through that village by village in which Irvine schools come with your house.

Not Every Irvine Address Is in IUSD

This catches people every year. An Irvine address does not guarantee IUSD. Parts of north Irvine, including much of Orchard Hills, are in Tustin Unified. That's a well-regarded district too, but it's a different district, with different schools, boundaries and calendars. If IUSD specifically is part of why you're buying, verify the district before you fall in love with a floor plan.

Why This Keeps Showing Up in Home Values

I'm careful here, because school rankings get oversold in real estate marketing. A test-score headline doesn't add a set dollar amount to a home's price, and I'd be skeptical of anyone who tells you it does.

What I can tell you from working in Great Park and Portola Springs every day is this. For a large share of the families I work with, IUSD is a hard requirement. They aren't weighing it as a nice extra. That steady demand from school-focused buyers has helped these villages through slower markets, because the pool of buyers who want in doesn't go away. A ten-year track record makes it easier for those buyers to commit, and that consistency is worth more to them than any single year's ranking.

If you're selling, it's worth highlighting. If you're buying, plan on competing with families who have the same priority you do.
