Haas School of Business at UC Berkeley is highly reputable (regularly ranks in the top 10 of all US MBA programs). There are a lot of universities (and low-level colleges) offering degrees in business administration, but not many schools have the same cachet carried by a name like UC Berkeley. Employers know and trust UC Berkeley because of their reputation for academic rigor and selectivity. That means, when faced with applicants (all other qualities equal) with credentials from University of Phoenix versus UC Berkeley, the employer is much more likely to go for the applicant with the education from UC Berkeley.How good is Business administration certification for changing career in UC Berkeley Extension?
First of all, its great to get exposure to the language and structures of business. If nothing else, its a great way to show an employer that you're serious about changing your career. I would highly recommend it. If you decide to go back for an MBA, it will also give you a leg up in business school and look great on your applications!
