Illinois School Districts: Complete Guide to 851 Districts, Jobs & Salaries (2026)

With 851 public school districts, a $55,000 minimum teacher salary, and $45 million in state funding to fight the teacher shortage, Illinois is one of the most active states for education hiring in 2026.

Whether you're searching for your first teaching job in Illinois or considering a move to the Prairie State, this guide covers everything you need to know — from district organization to salary data and where to find open positions.

Illinois School Districts: By the Numbers

Illinois has 851 public school districts as of 2025, making it one of the states with the most districts in the country. According to ISBE and Ballotpedia, here's how they break down:

| District Type | Count | Grades Served | |--------------|-------|---------------| | Elementary Districts | 367 | PreK-8 | | Unit Districts | 387 | PreK-12 | | High School Districts | 96 | 9-12 | | Other (Juvenile Justice, Co-ops) | 3 | Varies | | Total | 851 | |

This three-tier structure is unique to Illinois. In most states, a single district covers all grades. In Illinois, your elementary school and high school may be in entirely different districts with different administrations, tax bases, and pay scales.

Why Does This Matter for Job Seekers?

  • More districts = more job opportunities. Each district has its own hiring process, salary schedule, and benefits package
  • District boundaries cross county lines — don't limit your search to a single county
  • Elementary districts hire PreK-8 staff only — if you want to teach high school, you'll need to apply to a unit or high school district
  • Pay can vary dramatically between adjacent districts, even in the same region

Top 10 Largest Illinois School Districts

The biggest districts dominate the state's education landscape. Here are the largest by enrollment, based on data from CPS and Niche:

| Rank | District | Enrollment | |------|----------|-----------| | 1 | Chicago Public Schools (District 299) | ~316,200 | | 2 | Elgin Area School District U-46 | ~34,550 | | 3 | Rockford School District 205 | ~27,660 | | 4 | Indian Prairie School District 204 | ~26,000 | | 5 | Community Unit School District 300 (Algonquin) | ~20,000 | | 6 | Plainfield CCSD 202 | ~18,000 | | 7 | Valley View School District 365U | ~18,000 | | 8 | Naperville CUSD 203 | ~16,070 | | 9 | Schaumburg CCSD 54 | ~15,070 | | 10 | Township High School District 211 (Palatine) | ~12,270 |

CPS context: Chicago Public Schools is by far the largest district, but enrollment dropped 2.8% (~9,000 students) in 2025-2026 after two years of modest gains, according to Chalkbeat. Despite declining enrollment, CPS continues to actively hire due to retirements and turnover.

Other major districts worth researching include Springfield SD 186, Joliet Township HSD 204, Peoria SD 150, Aurora East USD 131, and Waukegan CUSD 60.
