Where this comes from
Illinois State Board of Education, Teacher Salary Study publishes Every district's salary schedule in reference points (Teacher Salary Study 2025-26), which every Illinois district files each year. The full step-and-lane grid is published by the district itself; this page carries the figures the state collects, which is what the salary-estimate sites do not have.
