Southlake's 76092 ZIP code holds the highest school score in the Dallas-Fort Worth metro at 92 out of 100, according to NeighborScore's stored ZIP-level scoring data. Flower Mound's 75022, Frisco's 75033, Colleyville's 76034, and Plano's 75024 round out the top five, each combining strong K-12 outcomes with the low crime rates that define these suburbs. Every ZIP below is ranked by NeighborScore's composite index, which blends crime and school performance into a single 0-100 number.

Best School Districts Dallas Fort Worth Suburbs Offer, Ranked

These five ZIPs post the highest school scores among Dallas-Fort Worth suburbs with complete NeighborScore data, ordered from strongest to weakest school performance:

1. Southlake (76092) — school score 92/100, overall composite 94/100. Carroll ISD anchors this ZIP, and its crime score of 95 is among the highest in the metro.
2. Flower Mound (75022) — school score 86/100, overall composite 91/100. Lewisville ISD campuses in this ZIP post some of the strongest reading proficiency rates in the ranking.
3. Frisco (75033) — school score 84/100, overall composite 90/100. Frisco ISD elementary campuses here report math proficiency above 80%.
4. Colleyville (76034) — school score 83/100, overall composite 89/100. Grapevine-Colleyville ISD elementary schools in this ZIP cluster in the 74-82% math proficiency range.
5. Plano (75024) — school score 84/100, overall composite 82/100. Plano ISD's westernmost ZIP has a lower crime score (80) than the other four, which pulls down its overall composite despite comparable school performance.

Southlake's lead is not close. A 92 school score puts 76092 six points ahead of the next-best ZIP, and its overall composite of 94 makes it the highest-scoring residential ZIP code in the entire Dallas-Fort Worth metro on NeighborScore's data, not just among schools. Flower Mound and Frisco cluster tightly behind it, separated by two points of school score, while Plano's 75024 shows that a strong school score alone does not guarantee a top overall ranking once crime is factored in.

How NeighborScore's Composite Index Rates DFW School ZIPs

NeighborScore's composite index is a weighted blend of two component scores: overall_score = crime_score × 0.53 + school_score × 0.47. Safety and school quality are the only two inputs; there is no hedging in that formula, and no other factor moves the headline number. A third component, the affordability or value score, is calculated and displayed on every ZIP profile, but it is intentionally excluded from the overall composite — it exists purely as context for how a ZIP's home prices compare to the Texas state median, not as a quality grade.

That distinction matters in this ranking. All five ZIPs above carry a value score between 16 and 27, well below the Texas statewide median value score of 50, which means every one of them is priced at a premium relative to a typical Texas ZIP. Southlake's 76092 and Colleyville's 76034 are the most expensive of the group, yet neither loses ranking position for it, because affordability plays no role in the school-district ranking itself. A family comparing DFW suburbs on school quality alone should weight the school_score column above, and treat the value score as a separate budgeting input.

What NCES Data Shows in Southlake and Flower Mound Schools

Individual campus data backs up the ZIP-level scores. According to the National Center for Education Statistics's Common Core of Data and EDFacts proficiency files (NCES / EdFacts), Old Union Elementary in Southlake's 76092 ZIP reports 92% math proficiency and 92% reading proficiency, the strongest combined result of any campus in this ranking. Eubanks Intermediate and Carroll Middle, also in 76092, each report 92% math proficiency, showing the strength is not confined to one school but runs across Carroll ISD's elementary and middle grades in that ZIP.

In Flower Mound's 75022, Wellington Elementary posts 82% math and 84% reading proficiency, while McKamy Middle reports 83% math proficiency — both comfortably ahead of the district-wide averages that feed the school_score for that ZIP. The gap between a ZIP's best campus and its weakest one is also worth watching: 76092's Florence Elementary reports 78% math proficiency, nearly 15 points below Old Union in the same ZIP, which is a reminder that a strong ZIP-level score is an average, not a guarantee for every individual school.

Parents cross-checking a specific campus before enrolling should pair this ZIP-level view with a school-by-school lookup on GreatSchools, which layers in parent reviews and state test-score trends alongside the same federal proficiency data.

Home Prices Across the Top DFW School ZIPs

Top school scores in DFW carry a real price tag. Southlake's 76092 has the highest median home price in this group at $1.375 million, with a median rent near $6,000 a month, homes selling in about 20 days, and a sale-to-list ratio of 98.4% — evidence that demand is still outpacing supply even at that price point. Colleyville's 76034 is close behind at roughly $1.02 million, also moving in about 24 days.

Frisco's 75033 and Flower Mound's 75022 sit in a more moderate band, at roughly $704,000 and $775,000 median price respectively, with days on market stretching to the low-to-mid 40s in Frisco — a sign of slightly less competitive bidding than Southlake or Colleyville. Plano's 75024 is the most accessible entry point of the five at around $670,000, though its median rent of roughly $1,744 is also the lowest, reflecting a different, less owner-occupied housing mix; homeownership in that ZIP runs near 38%, compared with 85-97% in the other four.

Bottom Line

Southlake's 76092 is the best-rated school ZIP in the Dallas-Fort Worth suburbs, scoring 92/100 on schools and 94/100 overall on NeighborScore's crime-and-school composite. Flower Mound, Frisco, Colleyville, and Plano fill out a tight second tier, each scoring between 82 and 91 overall, and each commands a premium home price well above the Texas median. Families prioritizing school quality alone should look first at the school_score column; those weighing budget should treat the lower value scores here as the cost of that quality, not a flaw in the ranking.
