No, requiring 10 papers for a Ph.D. is generally not a reasonable or standard requirement. While publications are highly valued and can enhance a Ph.D. student's research record, they are not universally mandatory for graduation.if you publish 10 or more reasonable articles from your PhD studies, you should be assured a reasonable shot at a faculty position. R1 (doctorate-granting) universities have this as a rough guideline for their Assistant Professor searches. Of course, if these articles are mostly from leading journals it improves your odds still more.Those students who have met my guidelines have been able to launch successful academic careers. Those who haven’t have had a harder time. In particular, there is no guarantee that a post-doc will work out. I have had students who went on to two or more post-docs with little in the way of published output. But because they published so much from their graduate studies, they were able to survive that dangerous chasm.
