California to Texas is the largest state-to-state migration corridor in the United States. According to Texas Realtors' 2024 Relocation Report, approximately 102,000 Californians moved to Texas in 2022 alone, and HireAHelper's analysis of 18 million moves between June 2024 and May 2025 found California still accounts for 14% of all new Texas residents, more than any other state. The reasons are familiar: housing costs, no state income tax, more space, and job opportunities in Austin, Dallas, and Houston.
But families with school-age children have a question that the cost-of-living math doesn't automatically answer: what happens to their kids' education? California and Texas have very different school systems, very different assessment standards, and very different experiences depending on which specific district you land in. This comparison covers what relocating families actually need to know.
The State-Level Data: Who Performs Better?
Comparing California and Texas schools at the state level requires acknowledging upfront that each state uses different assessments, different standards, and serves student populations with different demographic profiles. A raw comparison of state test scores is not a fair apples-to-apples measure of school quality.
On the National Assessment of Educational Progress, known as NAEP, the only common measure that applies the same test in every state, the most recent 2024 results show Texas 4th graders scoring 241 in math versus a national average of 237, according to the Texas Education Agency's January 2025 announcement. California 4th graders scored 233 in math, below the national average of 237, according to EdSource's analysis of 2024 NAEP results.
In 8th grade math, both states saw declines mirroring national trends, but Texas's English Learner students ranked first in the nation in 8th grade reading and math, a notable bright spot in otherwise challenging post-pandemic data. The Learning Policy Institute's May 2025 analysis of demographically adjusted NAEP scores found both California and Texas among nine states that showed large gains between 2019 and 2022, though progress in many states has stalled since.
The Urban Institute's 2024 demographically adjusted NAEP rankings, which control for student poverty rates, racial composition, and other demographic factors to measure school system effectiveness independent of student background, place Texas ahead of California on adjusted 4th grade math. On reading, the gap is narrower. Neither state is in the top tier nationally on adjusted measures, but Texas performs somewhat better than California when controlling for demographics.
What this means practically: on the best available common measure, Texas schools are producing slightly stronger outcomes for comparable student populations than California schools. The difference is real but not dramatic at the state level. Where the comparison gets far more significant is at the district and school level.
The Assessment System Difference: CAASPP vs STAAR
One of the biggest practical surprises for families moving from California to Texas is that the school grading and testing systems are completely different, and the proficiency thresholds are set differently enough that a score that seemed average in California may look different against Texas standards.
California uses the CAASPP assessment system based on Smarter Balanced tests aligned to Common Core standards. Proficiency is reported as the percentage of students meeting or exceeding grade level. In 2024, 44% of California 4th graders scored at or above proficient in English Language Arts on the state assessment, and 36.7% met grade-level standards in math. These numbers look concerning, but California's Smarter Balanced test is widely considered one of the more rigorous state assessments in the country, meaning a California proficient designation is a demanding standard.
Texas uses the STAAR, or State of Texas Assessments of Academic Readiness. The state average for high school ELA on STAAR sits around 55% meeting grade level. The Texas system also assigns A through F accountability ratings to districts and campuses based on achievement and growth, which gives families a quick snapshot of school performance that California's dashboard-based system doesn't replicate as simply.
The key practical implication: don't try to directly compare your child's California test scores to Texas STAAR results. The tests measure different things at different thresholds. A student who was performing at grade level in California may score differently on STAAR initially not because their skills changed but because the assessment is structured differently. Most families report a brief adjustment period before their children's performance stabilizes on Texas assessments.
What California Families Will Gain
Families moving to the Texas suburbs that draw the most California migrants, the Dallas-Fort Worth suburbs, the Houston suburbs, and the Austin-Round Rock area, will often find school quality that is comparable to or better than what they left, particularly if they are coming from average California districts rather than from the state's elite suburban schools.
Texas suburban districts like Katy ISD, Frisco ISD, Plano ISD, and Round Rock ISD consistently post STAAR ELA scores in the 80% to 91% range at their top campuses. The strongest California suburban districts, like those in Orange County or the San Diego north county corridor, also post scores in this range. But the average California district performs below the national average on NAEP, and a family moving from a mid-tier California district to a top-tier Texas suburban district will typically see stronger academic outcomes for their children.
The student-to-teacher ratio is a specific area where Texas often outperforms California. Texas schools have significantly more staff per student than California schools. A report from EdSource found that California has roughly 66% as many staff as Texas for comparable school sizes, meaning a 1,000-student school in California would have about 48 teachers versus a higher number in Texas. Families accustomed to California's larger class sizes often notice the difference in Texas suburban schools.
Texas also has no state income tax, which indirectly affects schools by keeping more money in families' pockets and by making Texas competitive at recruiting higher-income households who contribute to the tax base. Property taxes in Texas are high compared to most states, which is how schools get funded, and high-property-value suburban districts benefit from this structure considerably.
What California Families May Miss
California spends more per pupil than Texas. California K-12 schools spend $18,020 per pupil annually, compared to Texas's lower per-pupil spending. That investment shows up in some areas: California maintains the highest average starting teacher salary in the country at $58,409 and an average teacher salary of $101,084, significantly higher than Texas's teacher pay. Families moving from California to Texas will find teachers earning considerably less, which affects who is attracted to the profession and retained in it over time.
California's diversity is also a feature of its schools that Texas suburban schools don't always replicate. California's public schools serve the most diverse student population of any large state, with large numbers of English language learners, recent immigrants, and students from dozens of language backgrounds. For families who value that diversity as part of their children's educational experience, the more homogeneous demographics of many Texas suburban districts may feel like a loss. The Fort Bend ISD area near Sugar Land is an exception, with one of the most demographically diverse suburban districts in Texas, but it's not representative of the Texas suburbs broadly.
Arts and enrichment programming in California has historically been more developed in some districts, though this varies enormously by specific school. California's larger per-pupil spending has supported programs in some districts that their Texas counterparts don't match. And California's extended school day and year in some districts gives students more instructional time than comparable Texas schools.
The Part That Actually Matters Most: Which Specific School
The state-level comparison is useful context but it shouldn't drive your decision. The variation within each state dwarfs the variation between them. The difference between a top Frisco ISD campus and an average Dallas ISD campus is far larger than the difference between the Texas and California state averages. The same is true in California: the difference between a Irvine Unified school and a Los Angeles Unified school is enormous despite being in the same state.
The most important school research step for families relocating from California to Texas is identifying the specific district and specific campus their children would attend at the address they're considering. The top Texas suburban districts, Katy ISD, Frisco ISD, Plano ISD, Allen ISD, Round Rock ISD, and Williamson County districts near Austin, post scores that compete with California's best suburban districts. The weakest Texas urban districts post scores similar to the weakest California urban districts.
Here's a rough mapping by California origin that might help:
Families leaving Orange County or San Diego's north county suburban corridor are moving from some of California's strongest school zones. They should target Frisco, Plano, Allen, Katy ISD's Seven Lakes or Tompkins zones, or the Westlake area of Austin to find comparable quality. Moving to an average suburban Texas district without this research could mean a step down from what they had.
Families leaving the Bay Area's mid-tier suburban districts, places outside the elite Palo Alto or Piedmont zones, will typically find comparable or better schools in the strong Texas suburban corridor. Round Rock ISD and Williamson County schools around Austin draw significant Bay Area migration and are well-suited to families from that background.
Families leaving Los Angeles Unified or other large urban California districts will almost certainly find stronger schools in suburban Texas, sometimes dramatically so. Texas's suburban districts near Dallas, Houston, and Austin consistently outperform LAUSD-equivalent urban districts on STAAR, often by margins of 30 to 40 percentage points.
The Curriculum and Culture Shift
Beyond test scores, California and Texas schools differ in curriculum emphasis and school culture in ways that families should anticipate.
Texas's social studies standards, particularly at the high school level, have been shaped by state-level politics in ways that produce a different historical and civic education than California's. The content covered in Texas history and government classes reflects the state's conservative-leaning curriculum standards. Families coming from California's more progressively oriented curriculum may notice differences in how topics like race, history, and civics are taught. This is not a quality issue in either direction but a genuine content difference worth being aware of.
Texas high school football culture is also a real thing, not a stereotype. In many Texas suburban communities, Friday night football is the central social institution of high school life in a way that has no real California equivalent. This is a feature for many families and a cultural adjustment for others. UIL, the University Interscholastic League governing Texas high school athletics and academics, runs the most comprehensive system of competitive academic events alongside sports of any state in the country, which is a genuine benefit for students who participate in academic competition.
Texas also requires a new personal financial literacy graduation requirement starting with the 2026-27 ninth-grade class, something California has not mandated. Students transferring in will need to account for this credit requirement when planning their schedules.
How to Research Schools Before You Move
The Texas Education Agency's school accountability ratings are publicly available at the district and campus level and give a quick A through F grade based on STAAR performance, growth, and closing achievement gaps. For any Texas address you're considering, you can look up the specific high school, middle school, and elementary school accountability rating before you commit.
On allk12, every Texas school has a scores page showing STAAR performance history with grade-level breakdowns and comparisons against state, district, and county averages. Browse schools by city across the major Texas metros: Frisco, Plano, Allen, Katy, Sugar Land, The Woodlands, Round Rock, Cedar Park, and Leander to see score histories and what parents in those communities are saying in the discussion boards. The community knowledge about what a school is actually like from the inside, from parents who moved from California and can make the direct comparison, is often the most useful information available.
