As a current student of the charter class of the GMBA at JHU Carey, I can attest to many advantages and disadvantages of this program... and I wouldn't mind discussing them with you personally if you wish (these will of course be my personal opinion and cannot be comparative to other schools since my experience is limited to this school).
At the moment, the entire class is engaged in our Innovation for Humanity project. We were all given a choice of four countries (Kenya, Rwanda, India, and Peru), we were asked to rank them by preference and also rank our areas of interest (Micro finance, Healthcare, Energy, and Entrepreneurship). Based on your choices they did their best to meet your interests and create groups of 5-6 students to go to these countries and work with locals developing specific projects for 3 weeks. At the moment I am in Rwanda (Kigali) and have been here for close to two weeks. Our projects have been very intense and we have been working a lot, this has been an outstanding experience and for this I do have a comparison to make with other top B-schools.
Harvard and other schools have come here to do similar projects since the beginning of the year, and we have met with many of the same people (Government Ministers, Chamber of commerce, businessmen, tour operators, drivers, etc) and they have all told us that we are a stark contrast to the other schools. They all seem to agree that we have a very different attitude about being here, that we are here to work, not vacation, and that we don't mind getting our hands dirty and work out problems from the bottom up. The other 'better' schools seem to only want to deal with very high level people and are disconnected from the reality of the people. Oh yeah, and we are much friendlier...
Needless to say, we are all very happy and proud to hear these comments, but we believe this is part of the spirit Carey is trying to create in its students. We don't think we 'deserve' anything, we don't think that people owe us anything for being here. We work very hard everyday and believe it is our privilege to be here, we are here to help and learn, not to do anyone a favor.
Therefore, I think that at least as far as these types of projects are concerned, I think we are learning more and getting a lot more out of this experience than the other schools are.
Oh, by the way, all of our expenses (flight, hotel, cash packets, tours, meals, etc) are included in the tuition... I don't know about other schools, but students from Harvard told us that it cost them more than 5k each out of pocket to come.
The internet is really unstable here, so I have tried to upload the message a few times unsuccessfully, I hope I am not flooding the board with the same message 5 times... if I did, my apologies...
My two cents...
