How important is AACSB or ACBSP accreditation?

[innen_oda]

Is it really important or not really?

It generally matters to two groups:

1. Universities that need something to put in their advertising brochures to convince you to give them money.
2. Students who need something to convince themselves their university choice was the right one.

The first one frequently begets the second one, for obvious reasons.

If your university offers some sort of additional accreditation, that's great, but I would value a multitude of other factors (quality of instruction, how much debt you'll go into to pay for the degree, resources offered to students, convenience of the coursework and schedule in your life, etc etc) LONG before I considered this as a deciding factor.

You're probably not going to put this on your CV unless you REALLY have nothing else to offer, mentioning it during an interview looks desperate, and I've never seen a private-sector job adverts specifying any of these business accreditations. They probably exist somewhere, and perhaps the public sector, somewhere, in some county, requires them - but I've yet to see them myself.
