Illinois Mathematics and Science Academy
organization in Aurora, United States

The Illinois Mathematics and Science Academy, or IMSA, is a three-year residential public secondary education institution in Aurora, Illinois, United States, with an enrollment of approximately 650 students.
Enrollment is generally offered to incoming sophomores, although younger students who have had the equivalent of one year of algebra and a 9th-grade science equivalent are eligible to apply. All applicants undergo a competitive admissions process involving the review of transcripts, teacher and counselor evaluations, student essays, and SAT or ACT scores. Historically, approximately one-third of applicants in any given year are admitted. Due to its nature as a public institution, there are no charges related to tuition, room, and board; however, there is an annual student fee that may be reduced or waived based on family income.
Most people accepted to IMSA live in the state of Illinois; however, a limited number of out-of-staters are accepted each year. They are primarily from neighboring states, such as Wisconsin, Indiana, and Kentucky.
History
The school's founding president was former Batavia Superintendent Stephanie Pace Marshall, who was involved with the project from the start and, with the school's first legal counsel Richard L. Horwitz, helped form IMSA's original legislation, governing bylaws, and slogan. Marshall retired from the position on June 30, 2007, and was later named President Emerita by the Board of Trustees.
Although the school received a budget cut in financial year 2002, its budget has since increased with the support of House Minority Leader Tom Cross.

Why this record matters
“Illinois Mathematics and Science Academy” is worth following because a concise public description often conceals a longer documentary argument. Here, Illinois, Mathematics and Science provides the most credible route into that argument.
The record creator and administrative purpose are central evidence, because official documentation reflects both action and institutional priorities. The source revision retrieved here is dated Aug 9, 2026. The linked authority identifier is Q5999555. VIAF identifies the subject as 128196288. The Library of Congress control number is no2004096965. Authority coordinates are 41.786, -88.355. 4 of 5 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 2007 and 2002.
Later summaries often reconcile disputed chronology or motive more neatly than the contemporary record permits. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
