Accreditation is a cornerstone of quality assurance in higher education, particularly in technical and professional disciplines where consistency, rigor, and industry relevance are essential.

This chapter explores ABET’s origins and evolution, its influence on engineering technology education, and the distinctions it draws between engineering and engineering technology curricula.
