Community High School District 99

What Community High School District 99 does

Community High School District 99 is a public school district organized under Illinois state law and governed by a 7-member elected Board of Education, serving approximately 4,630 students in grades 9-12 (plus transition services for ages 18-21) across two comprehensive high schools — Downers Grove North High School and Downers Grove South High School — and the Transition 99 Center in Downers Grove, Illinois. The district's geographic attendance boundaries cover Downers Grove, Woodridge, and portions of Bolingbrook, Darien, Lisle, Oak Brook, and Westmont, with a service population of more than 65,000 residents. Revenue is generated primarily through local property taxes and Illinois state education funding, supplemented by minor student activity fees, fiduciary funds, and out-of-district summer school tuition ($210 per course in-district; $420 out-of-district; $670 for out-of-district Driver's Education).

The district's technology stack is standard K-12 EdTech procurement: Infinite Campus serves as the student information system, ParentSquare as the family communication platform (with translation capabilities), BluePoint as a rapid emergency response system with hardware pull-stations, Finalsite as the website platform, and Renaissance STAR as the assessment tool. Proprietary operational programs include a Relationship Mapping process (identifying on average 7 positive student-staff connections that triple by a student's 4th year) and the PATH (Pause, Act, Think, Heal) behavioral intervention program with recidivism rates of 14% (North) and 17% (South). The district maintains four office locations totaling over 1 million square feet, supported by 700+ full-time staff including specialized roles in equity and inclusion, special education, mental health, and student support services. The district was established on February 17, 1923, celebrated its centennial in 2023, and is not a traditional investable entity — it has no parent company, no institutional investors, and is not publicly traded.

• Township High School District 211: Illinois township high school district serving Palatine and surrounding suburbs with multiple comprehensive high schools of similar scale.

• Indian Prairie Community Unit School District 204: K-12 district serving Aurora and Naperville with extensive STEM, language immersion, and AP programming. Comparable on suburban Chicago demographics, high-achieving outcomes, and programming depth; a peer for benchmarking district-wide initiatives like equity and biliteracy.
• Township High School District 214: Large Illinois township high school district in Arlington Heights serving multiple communities with comprehensive high schools and specialized programs. Directly comparable to D99 in operating model, scale, and DuPage-adjacent Chicago suburb context, often cited as a regional peer on outcomes and CTE programming.
• Hinsdale Township High School District 86: Neighboring DuPage County high school district serving Hinsdale and Clarendon Hills. Directly comparable on demographics (affluent Chicago suburb), product (grades 9-12 public education), and funding model; the most local head-to-head competitor for families at district boundaries.
• Evanston Township High School District 202: Single-school Illinois township high school district north of Chicago. Comparable on the township-HS-district structure, comprehensive programming, and equity-and-inclusion focus; often referenced in Illinois policy discussions alongside D99.
• Naperville Community Unit School District 203: Large K-12 community unit district in the western Chicago suburbs operating multiple high schools.

Broad incumbents

• Stride Inc. Publicly traded provider of online and blended K-12 education programs, including full-time virtual schools and career-learning offerings. Overlaps with D99's high school product but as a broader, multi-state operator and alternative-format competitor rather than a single-site district.

Emerging players

• KIPP Public Schools: National network of public charter schools operating college-prep programs primarily in urban communities. Comparable on public-school mission, college-readiness focus, and wraparound student supports, but serves a fundamentally different demographic and operates under charter-authorization governance rather than as a traditional district.
