One of this site's most useful innovations is its top ten lists to show which schools are most effective at getting students into specific roles: http://find-mba.com/lists

What's notable is that many of these schools don't support formal concentrations or specialisations that are recorded on transcripts or formally noted.

It's different in India and Pakistan, where the MBA has two distinct forms: not only a degree centred on the core general management body of knowledge (as an MBA is in the west); but also a specialised masters degree which is mostly composed of specialised content (like a master of science degree in the west).

Many applicants, especially those from Asia, feel that they need to select only from the business schools that offer the specialisation they want to take, and also that they need to choose a specialisation in advance of applying. Both of these are mistaken.

Business schools may or may not offer formal concentrations or specialisations. As a rule of thumb, mainstream MBA employers don't care about them too much. If two strong students have taken similar courses and performed similarly well at schools that don't have majors, like Harvard or Dartmouth, no-one will select an average student from Wharton just because he has a major in a topic.

So, if you want to move into a particular direction in your career then take a look at the schools that are best able to place alumni into the schools you want to attend, rather than to focus only on those with formal specialisations. LinkedIn is a great resource here (see How to use LinkedIn to find the best school www.find-mba.com/board/33571).

Furthermore, don't forget that many students change direction either in their MBA or later in their career. Having an MBA that puts you into tracks early has advantages. For example at Cornell you can (painfully) do all the core courses in one semester, and then take a concentration in the second semester (https://www.johnson.cornell.edu/Two-Year-MBA/Curriculum/Immersion-Learning). That allows students to hit the ground running in their summer internships. That is great for people who know in advance that the vast range of opportunities presented by the MBA will not change their mind about where their passion is. Of course, the whole point of the MBA is that it broadens your choices. I have seen many students change direction during their MBAs, and others feel locked in because their specialised MBA mispositions them as a functional specialist rather than a general manager.

So, focus on the school that will get your the choices and outcomes you want, and not just te formal specialisations.

Duncan, what about compare two alumni from one university, for the same position?)
Also, for MBA with concentration you should pay more, for example, in The University of Texas Permian Basin it starts from $12900:

But the usual MBA fee is $11700, you can choose only one marketing course:

Actually, 3 credits cost $1100, so the difference should be $2200. I'm curious is if possible to save one grand and learn something from Marketing research course if you just buy and thoroughly read the following  textbook:
Marketing research: Using analytics to develop market insights (Rev: 12th ed.)Publisher Wiley (2021)Author McDaniel, C., Jr., & Gates, R.ISBN 9781119716310Price $94.70

I don't think there is any evidence to suggest that people with MBA specializations are paid more than those without. 

PS Your question about UTPB isn't really relevant to this thread.
