Northcentral offers undergraduate and graduate programs on master and doctorate levels, and specializes in online one-on-one format. Most professors are very knowledgeable and helpful. The online format can be isolating and restricting in some courses--compared to other online universities, if the professor has not specialized in interdisciplinary studies. Collaboration with peers is rare, which detracts from learning and involvement in a discipline that is crucial in today's globalization. The online curriculum is built for/on already established, busy professionals' needs, to attain an advanced degree. It is a private, expensive, research university. Researching however, is very rewarding with well-trained research librarians.
