Most brick-and-mortar MBA programs at state schools (for example, Michigan State, Arkansas State, University of Florida) are AACSB accredited. Some brick-and-mortar schools offer online degrees as well. If you want to see if a particular program is AACSB accredited, the first place to look is the AACSB website. Their website has a list of all accredited programs.
Some schools may not have the accreditation but can still be members of the AACSB. It is crucial to visit the AACSB website to ensure that a program is accredited if such accreditation is crucial to your future plans.
