The sources you should trust
District 303 attendance boundaries
Use the district’s interactive tool to confirm the assigned elementary, middle, and high school for a specific address. Start here: District 303 attendance boundaries.

Illinois Report Card (ISBE)
ISBE provides official annual data on proficiency, graduation rate, summative designations, student groups, spending, and more. In ISBE terms, “proficiency” means the percent of students meeting or exceeding state standards. Read about the latest statewide release and what it includes: Illinois Report Card release summary.
NCES and community context
The National Center for Education Statistics lists enrollment, student‑teacher ratios, and district snapshots. It is helpful for broad comparisons and trend checks: NCES District 303 profile.
Local reporting and board materials
Local media recap board decisions that affect homeowners, including the annual tax levy. For 2024, D303 approved a levy near $199.5 million with a projected district component tax rate estimate around 4.808 percent. See the recap: Shaw Local coverage of the 2024 levy.

Key metrics to decode
Attendance boundaries and assigned school
Attendance zones determine which schools serve a specific address. Because D303 updated maps for 2024–25, always confirm assignment using the district boundary tool and review the boundary updates page if you are near a border. This is usually the most important step for families.
Summative designation and proficiency
ISBE’s summative designations (such as Exemplary or Commendable) summarize multiple indicators, while proficiency shows the percentage meeting or exceeding standards in each tested subject. Compare the same school across several years to spot trends. Learn what the state release includes here: Illinois Report Card overview.
Graduation rate and on‑track
Graduation rate reflects the percentage of students who finish in four years, and ISBE also reports 9th‑grade on‑track indicators. Recent local summaries have cited D303 graduation rates near the low 90s. Check the latest report year when you compare schools: Report Card context via IASB.
Per‑pupil spending and the tax levy
Per‑pupil spending shows how much the district spends per student across instruction and support. Local coverage has placed D303 spending in the high‑teens to around $20,000 per student depending on the reporting year. For homeowners, the annual levy matters too. In December 2024, D303 approved a levy just under $200 million and projected a district component tax rate estimate near 4.808 percent. Final tax bills depend on Kane County’s equalized assessed value and tax extensions. See: Shaw Local levy recap.
Student demographics and services
ISBE and third‑party aggregators show district demographics, including the share of students who are economically disadvantaged, receive special education services, or are English learners. Aggregators have reported D303’s economically disadvantaged percentage in the mid‑teens; always note the source and year and cross‑check with ISBE. For a supplemental snapshot, see Niche’s D303 overview.
Student‑teacher ratio and staff experience
NCES lists student‑teacher ratios for the district, which have been about 13 to 14 students per teacher in recent reporting. Ratios vary by grade level and course. Review the current profile here: NCES District 303 profile.
Capacity, crowding, and boundary changes
Boundary revisions are often tied to capacity. D303’s 2024–25 updates addressed overcrowding, so if a home is near a boundary line, factor in the possibility of future adjustments. Start with the district’s boundary updates overview.
Transfers within or into D303
D303 accepts intra‑district transfer requests during posted windows. Students must register first, approvals depend on space, and families are generally responsible for transportation. See the current process and dates: Intra‑district transfer policy. Interdistrict transfers are not guaranteed and depend on agreements and capacity; check both districts for rules.
How to use school data in your search
- Confirm the assigned schools for each listing by entering the full property address in the District 303 boundary tool. Screenshot or save the results for your records.
- Pull the latest ISBE data for the assigned schools and note the year on each metric. Use the statewide release summary as a guide to what you will find on those pages: Illinois Report Card overview.
- Compare proficiency and summative designations across several recent years instead of relying on a single snapshot.
- Visit schools, attend public events, and review newsletters to understand programs, schedules, and student supports.
- Estimate taxes with care. The district’s 2024 levy is summarized here: Shaw Local levy recap. Final homeowner impact depends on Kane County’s assessed values and tax extensions.
- If you are targeting a specific school but a listing sits outside its zone, review the intra‑district transfer policy and decide whether the timing and transportation requirements work for your family.
A quick note on neighborhoods and taxes
School taxes are a major part of local property tax bills in St. Charles.
