Call the admissions office of the college or university you are interested in and ask if they are accredited with AACSB or ACBSP. The school should know what accreditation they hold, and should be able to answer this for you. If you doubt their information, or have other concerns, you can research the accreditation yourself. You can also find this information online by looking at the school's website and searching for the accreditation information.
Go online to ACBSP's website. Select the "About ACBSP" tab and select the "Accredited Programs" option. This will give you a list of accredited programs. Look for your school's name on this list and the specific program you are inquiring about. If they are on this list, then they are accredited.
Go online to AACSB's website. Select the ''AACSB-Accredited Institutions" link and see if your school is on the list. Schools are categorized by accreditation in business or business and accounting. Look for your school to verify if your school is accredited.
Call the offices of the AACSB or ACBSP accreditation directly and ask them to verify if your school is accredited. You may also want to clarify any discrepancy you find, or voice any concerns you have. You can call AACSB at (813) 769 6500, and ACBSP at (913) 339-9356.
