Biennial Report

The Biennial Report of the Illinois School for the Deaf in Jacksonville served as an essential administrative and public accountability document. Published regularly throughout the 19th and 20th centuries, these reports were designed to communicate the institution's operational status, enrollment statistics, and pedagogical advancements to the Illinois General Assembly and the public. They reflect the evolving educational philosophies regarding deaf education in the United States, transitioning from early institutional models to more formalized academic and vocational curricula.

These volumes often feature detailed accounts of the campus infrastructure, financial expenditures, and the academic progress of the student body. The design was typically utilitarian, prioritizing clarity and archival integrity to serve as a legislative record. While intended primarily as an official report for state oversight, the documents now function as significant primary sources for historians researching the history of disability, institutional care, and the development of American Sign Language within specialized educational settings.
