East County School Districts: A Family's Guide

For most families moving to East County, the school district is a top-three decision factor — often the top decision factor. And it should be: good schools shape your child's day-to-day experience for the next decade-plus, drive your social network, and meaningfully affect your home's resale value. In Contra Costa County, school zones can change pricing by 10–20% across an arbitrary line, with otherwise-identical homes selling for sharply different prices on either side.

Below is a practical district-by-district overview. None of this replaces actually visiting the schools you're considering, talking to current parents, and confirming current attendance boundaries (boundaries shift periodically) — but it's a strong starting point.

Why school districts matter — beyond academics

Three reasons school districts matter in East County, in order of importance for most buyers:

1. Day-to-day quality of your child's education. Strong districts have lower class sizes, better-trained teachers, more extracurriculars, and stronger college-prep programs. Top-rated zones translate directly into measurably better outcomes — graduation rates, AP enrollment, college acceptance rates.
2. Your child's social network. School determines who your kid grows up with, who their parents are, and what kinds of activities surround them. This is hard to quantify but matters enormously.
3. Resale value. Homes in top-ranked East County zones sell 8–15% higher than otherwise-identical homes in lower-ranked zones. They also sell faster. If you're a buyer who might move within 5–10 years, district has a direct dollar impact.

Liberty Union High School District

Communities served: Brentwood, Discovery Bay, Bethel Island, parts of Oakley, parts of Byron.

Liberty Union is the standout high school district in East County. It serves Brentwood, Discovery Bay, and surrounding rural East County, and consistently ranks among the strongest public high school districts in Contra Costa County.

Notable schools:

• Heritage High School (Brentwood) — flagship comprehensive high school, strong academics, robust athletics.
• Liberty High School (Brentwood) — older, established high school with strong arts and athletic programs.
• Freedom High School (Oakley) — Oakley families' default high school under Liberty Union.
• Independence High School — continuation/alternative program.
• La Paloma High School — alternative program.

Strengths: high school graduation rates, AP course offerings, college acceptance numbers. Heritage in particular has built a reputation as a strong feeder into UC and CSU systems.

If schools are your decision driver, Brentwood and Discovery Bay's draw is largely Liberty Union.

Brentwood Union School District (Elementary/Middle)

Communities served: Brentwood, parts of Discovery Bay, parts of Bethel Island.

Brentwood Union covers TK through 8th grade for the families inside Brentwood city limits. The district has been one of the highest-performing in Contra Costa for years, with multiple schools earning California Distinguished School designations.

Notable schools:

• Garin Elementary — frequently ranked the top elementary in East County.
• Mary Casey Black Elementary — newer, strong test scores and engaged parent community.
• Adams Middle School — solid academic and athletic programs.
• Bristow Middle School — strong music and STEM offerings.

If you're moving to Brentwood for the schools, this is the elementary/middle district that completes the picture alongside Liberty Union for high school.

Mt. Diablo Unified School District

Communities served: Concord, Pleasant Hill, Clayton, Bay Point, parts of Walnut Creek, parts of Martinez.

Mt. Diablo Unified is the largest district in Contra Costa County and serves much of Central County plus East County's Bay Point. Quality varies dramatically across schools — some of the strongest individual schools in the East Bay are within Mt. Diablo Unified, and so are some of the weakest. School-by-school evaluation matters more here than district-level.

Standout schools:

• Northgate High School (Walnut Creek) — consistently ranked among the strongest public high schools in California.
• Walnut Creek Intermediate — feeds into Northgate; strong academics.
• Walnut Heights Elementary — top elementary in Walnut Creek.
• College Park High School (Pleasant Hill) — strong academic and athletic profile.
• Strandwood Elementary (Pleasant Hill) — repeatedly top-ranked.
• Clayton Valley Charter High School (Clayton) — top-ranked charter, popular with Clayton and Concord families.
• Mt. Diablo Elementary (Clayton) — top elementary in Clayton.

Weaker pockets exist in parts of Concord (some elementary and middle schools have struggled with consistency), and the Bay Point–served schools have generally lower test scores than the Central County schools. Boundary research is critical here.

Antioch Unified School District

Communities served: Antioch.

Antioch Unified covers the city of Antioch from K through 12. The district has improved meaningfully over the past decade, with newer schools in the Hillcrest and Lone Tree corridor showing strong academic results, while older central Antioch schools have had a more uneven record.

Notable schools:

• Dozier-Libbey Medical High School — selective specialized high school focused on health science careers; one of the highest-rated public high schools in the East Bay.
• Lone Tree Elementary, Diablo Vista Elementary, Carmen Dragon Elementary — newer schools in the Hillcrest/Lone Tree area, generally well-regarded.
• Deer Valley High School — large comprehensive high school with strong athletics.
• Antioch High School — older comprehensive high school, recently invested in.

Antioch is genuinely a value play if you're thoughtful about specific schools and zones. The Hillcrest corridor schools punch well above the district average.

Oakley Union Elementary School District

Communities served: Oakley, Bethel Island.

Oakley Union covers TK–8 for Oakley and Bethel Island. It's a smaller, locally-focused district with a few strong elementary schools and a generally well-regarded middle school program. Oakley high schoolers feed into the Liberty Union district (Freedom or Heritage), which is one of the upsides of buying in Oakley.

Notable schools:

• Vintage Parkway Elementary — well-regarded, strong parent community.
• Iron House Elementary — newer school, good test scores, popular with Magnolia Park / Summer Lake families.
• O'Hara Park Middle School — reliable middle school.
• Delta Vista Middle School — newer middle school, strong academics.

For families willing to look slightly outside Brentwood, Oakley offers a real package: Oakley Union for K–8 plus Liberty Union for high school, often at meaningfully lower home prices than Brentwood proper.

Pittsburg Unified School District

Communities served: Pittsburg.

Pittsburg Unified covers all grade levels in Pittsburg. The district has had a more uneven track record than its neighbors but has invested significantly in newer facilities (the new Pittsburg Center BART–adjacent schools, in particular) and strong athletic programs. Pittsburg High School is well-known regionally for its sports programs (football and basketball especially) and has strong CTE (career-technical education) offerings.

For first-time buyers prioritizing affordability, Pittsburg can work — it just requires more careful school-by-school due diligence than the higher-rated districts.

Private and charter options

East County's private and charter scene has expanded significantly. A few to know:

• Heritage Christian School (Brentwood) — K–12, faith-based, well-regarded academically.
• Liberty Christian School (Antioch) — K–8, established.
• Holy Rosary School (Antioch) — K–8, Catholic.
• Hilltop Christian Schools (Antioch) — K–12, Christian.
• Clayton Valley Charter High School (Clayton) — large public charter, very popular with Clayton/Concord families.

Private school tuition runs roughly $12,000–$25,000 annually for elementary/middle, and $20,000–$40,000 for high school. Some families also commute to private schools in Walnut Creek or Lafayette (Athenian, Bentley, College Preparatory) — drives are typically 30–45 minutes each way during peak times.

How school zones affect home value

In a typical East County market, two otherwise-identical 4-bedroom homes can sell for materially different prices based on which side of a school district line they sit on. Examples we see regularly:

• Brentwood homes inside top elementary zones (Garin, Mary Casey Black) often command $50,000–$100,000 premiums vs. similar homes in lower-ranked zones across town.
• Walnut Creek homes inside the Northgate High attendance zone routinely sell 10–15% higher than otherwise-comparable homes in adjacent (technically Walnut Creek but different attendance) zones.
• Antioch homes inside the Dozier-Libbey lottery feeder zone get a measurable premium.

When you're evaluating homes, always confirm the current attendance boundaries with the district directly — boundaries shift, magnet/lottery rules change, and real estate listings sometimes reference boundaries from 2 or 3 years ago.

A practical recommendation

If schools are a top decision driver:

1. Decide on the top 2–3 districts based on your priorities.
2. Identify the specific schools your kids would attend (use the district's GIS/boundary tool or call the office).
3. Visit the schools in person if possible — even from the parking lot during dismissal, you'll learn things from the energy.
4. Talk to 2–3 current parents at each school. Ask about teacher quality, parent involvement, and what they wish they'd known.
5. THEN start looking at homes inside those specific zones.
