The US doctoral system is one that requires coursework and a dissertation. Some systems outside the US, some in SA being an example, require only a dissertation. We see regular questioning of rigor and pedagogy addressed to several US institutions that require coursework and dissertations. We can make biased assumptions about one system or the other, but without hard data, this would just be conjecture and opinion. Some might say that these "foreign" programs are more rigorous on their dissertations, but the data would need to be supplied in a variety of ways to support this hypothesis. My question is, if a 250-page dissertation from a US institution matches a 250 page dissertation from a "dissertation only" institution in quality and rigor, then how do we see the extra coursework required in the US system. One might ask, is the rigor of the course work relevant at all if it is leading to dissertation that is critiqued and judged by a panel of legitimate scholars anyway? If we se the rigor of course work to be a significant and important part of the doctoral process, why do we not question the lack of this component for non-US universities? What if the NCA started accrediting new for-profit universities that required dissertation only? What sort of reaction might this engender?
