The latest data from the U.S. Department of Education shows that public colleges dedicate an average of 28% of their spending to student instruction. Taxpayer funding of higher education currently amounts to 80% of all spending by public and private colleges on functions that directly contribute to the education of students and the general public. This includes instruction (like teaching salaries and classrooms), public services (like informational conferences), and academic support (like libraries and information technology).
