Every school is certified or accredited by someone. The questions to ask are:
- do you want your MBA to be accepted by an organisation that requires high standards, like the triple crown, or average standards, like national academic accreditation. IBAS has neither.
- why would you want a degree without those credentials if one with it was available.

ACBSP is not a particularly strong accreditation.

for sure, i don`t like to waste time or money for non useful certification and i am not looking for low standards to follow.
i just wanna know, if i joined that academy, am i gonna become qualified enough to work and apply MBA rules in my work, and is it certified enough to work in any business company??
and what are the standards that i should consider when i take my decision to choose specific school to study MBA

Obviously, this depends on your work and the company you want to work for. IBAS claim their fees are CHF 24,800. I doubt that many students are paying even half that amount. There is no reason to study at IBAS when so many less costly schools exist with one or more of the Triple Crown accreditations (e.g., Deakin or Hull) or national accreditation allowing them to issue academic degrees (UoP, Amity). For the same amount you could take a world-class MBA like Illinois or Boston universities.

[quote]What is the difference between academic accreditation and professional accreditation?[/quote]

In a nutshell: imagine you want to be a barber. You don't go to university to become a barber. You go to a vocational or technical school. That's professional education. Generally, when a organisation in Europe wants to try to operate legally as a diploma mill, they will get certified as a provider of vocational education, and then they will get certified as a training centre below the university level, and then find some foreign organization that isn't well respected to accredit them.
