Credit is the foundation of US higher education because:
- it’s the building block of curriculum for the institution and diploma for the students.
- An institution develops its budget, majors, faculty ranks, etc based on the offering of credit courses.
- Accreditation of universities and colleges, articulation between institutions, transfer, conferring of degrees are all based on credits, wherever and however they are accumulated, within standards.
- AP and IB can be regarded as a practical extension of the use of credits
