The 2005 Illinois State Board of Education's 2005 Illinois District Report Card ISBE 2005 Report Card shows that the Seneca High School was strongly funded - in large part through payments made by Commonwealth Edison's power generation plant located approximately ten miles south of Seneca. For example, the above cited 2005 high school district Report Card shows the Illinois State average instructional expenditure per pupil at $5,216, but Seneca was able to provide $8,647 in instructional expenditures per pupil. Similarly, while the state average operating expenditure per pupil was $8,786, Seneca was able to dedicate $17,305 per pupil, which is reflected in the grade school, middle school, and high school facilities. These payments made by Commonwealth Edison have since decreased along with the impact they once had.
