DuPage County has 279 public schools serving roughly 141,500 students, and an outsized number of them rank among the best in Illinois. If you're relocating to the western suburbs or just trying to figure out whether your property taxes are doing anything useful — they are, actually — here's a data-backed breakdown of where the strongest districts are and what makes them worth the hype.
Why DuPage County Consistently Produces Top-Ranked Schools
DuPage isn't a fluke. The county regularly dominates statewide school rankings from Niche, U.S. News & World Report, and GreatSchools, and the reasons are structural:
Funding and property tax base. DuPage is one of the wealthiest counties in Illinois. High assessed property values translate directly into well-funded schools — better facilities, more AP offerings, competitive teacher salaries.
Community engagement. Districts here benefit from unusually high parent involvement and active school boards. That's not a soft metric. It shows up in graduation rates, extracurricular participation, and long-term college readiness.
Teacher retention. Competitive pay and well-maintained buildings mean DuPage districts attract and keep experienced educators at a higher rate than the state average.
The result: seven of the top ten school districts in DuPage County hold an A+ overall grade from Niche's 2026 rankings, based on U.S. Department of Education data, state test scores, college readiness, and graduation rates.
The Top-Ranked Public School Districts in DuPage County
Here are the highest-rated districts in DuPage County according to the Niche 2026 Best School Districts rankings, cross-referenced with U.S. News & World Report and Chicago Parent's 2025 reporting.
1. Hinsdale Township High School District 86 — Hinsdale
Niche grade: A+
Schools: 3 | Students: 3,765
Address: 5500 S. Grant St., Hinsdale
Hinsdale 86 has held the top spot in DuPage for years, and it's not hard to see why. Hinsdale Central High School ranks #9 in all of Illinois per U.S. News. The district has operated since 1887 and is known for exceptional college admission rates, deep AP course offerings, and a culture that emphasizes both academic achievement and character development. If you want the highest-ceiling public high school experience in the county, this is it.
2. Indian Prairie Community Unit School District 204 — Aurora
Niche grade: A+
Schools: 34 | Students: 25,950
Address: 780 Shoreline Drive, Aurora
Indian Prairie is the largest district on this list by a wide margin, and it still manages an A+ grade across 34 schools. Established in 1972, it's known for strong community involvement and tailored learning strategies. Metea Valley High School ranks #32 in Illinois. The district covers parts of Aurora, Naperville, Bolingbrook, and Plainfield — a genuinely diverse footprint by suburban standards.
3. Naperville Community Unit School District 203 — Naperville
Niche grade: A+
Schools: 22 | Students: 16,071
Address: 203 W. Hillside Road, Naperville
District 203 is basically synonymous with "good schools" in the Chicago suburbs. It offers rigorous AP coursework, strong STEM programs, and two highly ranked high schools: Naperville North (#26 in Illinois) and Naperville Central (#22). The district has grown alongside Naperville itself and continues to invest heavily in educational infrastructure. Parents here are not casual about academics, and the results reflect it.
4. Elmhurst School District 205 — Elmhurst
Niche grade: A+
Schools: 13 | Students: 8,330
Address: 162 S. York St., Elmhurst
Elmhurst 205 balances strong academics with well-regarded music, arts, and athletics programs. York Community High School ranks #37 in Illinois, making it one of the highest-performing individual schools in the county. The district emphasizes creativity and critical thinking alongside traditional college prep, which gives it a slightly different character than the more test-score-driven districts above.
5. Community High School District 99 — Downers Grove
Niche grade: A+
Schools: 2 | Students: 4,708
Address: 6301 Springside Ave., Downers Grove
District 99 runs two high schools — Downers Grove North (#59 in Illinois) and Downers Grove South — and both carry strong reputations. The district is known for award-winning arts programs, competitive athletics, and a genuine emphasis on student wellness. It's smaller and more focused than the mega-districts higher on this list, which some families see as a feature, not a bug. If you're weighing it against nearby Elmhurst 205, we did a full side-by-side for families.
6. Community Unit School District 200 — Wheaton
Niche grade: A+
Schools: 20 | Students: 11,632
Address: 130 W. Park Ave., Wheaton
District 200 covers Wheaton and Warrenville, operating two strong high schools: Wheaton North (#45) and Wheaton Warrenville South (#69). Formed from the consolidation of smaller districts in 1969, it offers honors and AP courses, robust extracurriculars, and strong athletic programs. The district leans into leadership development and community service — very on-brand for Wheaton.
7. Glenbard Township High School District 87 — Glen Ellyn
Niche grade: A+
Schools: 4 | Students: 7,747
Address: 596 Crescent Boulevard, Glen Ellyn
Glenbard 87 operates four high schools, and Glenbard West ranks #27 in Illinois — among the highest individual school rankings in the county. Founded in 1916, the district invests heavily in technology and career readiness. Each of its four schools has a distinct identity and specialized programs, which gives families more options than a typical single-school district.
What to Look for Beyond the Rankings
Rankings are useful. They're also incomplete. Here's what they won't always tell you about a DuPage County school district:
Class sizes and student-to-teacher ratios. A district can have a great overall grade but still pack 30 kids into a classroom. Check the numbers for specific schools, not just district-wide averages.
Special education and support services. If your child needs an IEP or 504 plan, the quality of support varies significantly between districts. Community Unit School District 201 in Westmont (Niche grade: A+, 1,333 students) is notably well-regarded for personalized learning and strong special education services — worth a look if that's a priority.
Extracurricular depth. Some districts offer deep benches in music, theater, robotics, and athletics. Others are academically strong but thinner in programming. Talk to current parents, not just the brochure.
School culture and diversity. DuPage County's demographics are shifting. Districts like Indian Prairie 204 serve a significantly more diverse student body than some of the historically whiter western suburbs. That matters for a lot of families.
How School Districts Affect DuPage County Home Values
We should be honest: school districts are one of the single biggest drivers of home prices in DuPage County. It's not subtle. Homes within the boundaries of Hinsdale 86, Naperville 203, and Elmhurst 205 consistently command higher price-per-square-foot values than comparable homes in lower-ranked districts — sometimes by tens of thousands of dollars. For a fuller picture of what you'll actually pay, check the latest DuPage County home price data. A few things to keep in mind:
District boundaries don't always follow city lines. A home in "Naperville" might feed into Indian Prairie 204 or Naperville 203 depending on the specific street. Always verify the district assignment before making an offer.
Elementary feeder patterns matter. Two homes in the same high school district can feed into very different elementary and middle schools. If you care about the full K–12 pipeline, dig into the feeder structure — we ranked the best elementary schools across the suburbs separately.
Tax rates vary. Higher-ranked districts often (but not always) come with higher property tax rates. DuPage County property taxes are already among the highest in the state — though some suburbs are considerably cheaper than others — so factor this into your monthly housing budget realistically.
The bottom line: buying into a strong district is a real investment, both in your kid's education and in your resale value. But don't overpay for a zip code without checking what specific schools your address actually feeds into.
Final Thoughts
DuPage County's public schools are, on the whole, genuinely excellent. Seven of the county's top ten districts earned an A+ from Niche in 2026, and several individual high schools rank in the top 40 statewide. That doesn't happen by accident — it's the product of strong funding, engaged communities, and decades of institutional investment. But "best" depends on what your family actually needs. A district that's perfect for a high-achieving high schooler gunning for a selective college may not be the best fit for a younger child who needs robust support services or a creative arts program. Do your homework — the schools certainly will.
