The AACSB claims that its accreditation provides evidence of business school quality in a variety of areas. This paper reviews and synthesizes existing research on the value of AACSB accreditation on four key topics of importance to schools, prospective students, and employers: effect on obtaining quality students, students' job placement, faculty recruitment, and teaching quality. The very limited research comparing AACSB to other business accreditation is also examined. Overall, the analysis indicates very mixed support, at best, for the claims of AACSB schools' superiority in these areas. This analysis should be useful for business schools, employers, and prospective business students.
