Postdocs most commonly, but not always, have a temporary academic appointment, sometimes in preparation for an academic faculty position. According to data from the US National Science Foundation, the number of holders of PhD in biological sciences who end up in tenure track has consistently dropped from over 50% in 1973 to less than 20% in 2006.WEB, Weissmann, Jordan, 2013-02-20, The Ph.D Bust: America's Awful Market for Young Scientists—in 7 Charts,weblink 2023-07-29, The Atlantic, en, They continue their studies or carry out research and further increase expertise in a specialist subject, including integrating a team and acquiring novel skills and research methods. Postdoctoral research is often considered essential while advancing the scholarly mission of the host institution; it is expected to produce relevant publications in peer-reviewed academic journals or conferences. In some countries, postdoctoral research may lead to further formal qualifications or certification, while in other countries, it does not.Postdoctoral research may be funded through an appointment with a salary or an appointment with a stipend or sponsorship award. Appointments for such a research position may be called postdoctoral research fellow, postdoctoral research associate, or postdoctoral research assistant. Postdoctoral researchers typically work under the supervision of a principal investigator. In many English-speaking countries, postdoctoral researchers are colloquially referred to as "postdocs".WEB,weblink NationalPostDoc.org, National Postdoctoral Association: Career Development Resources,weblink" title="web.archive.org/web/20150316003026weblink">weblink 2015-03-16, Job security in academia Due to the nature of their work in some fields,BOURNE > FIRST1 = P.

Post-doctoral appointments that were traditionally optional have become mandatory in some fields as the degree of competition for tenure-track positions in academia has significantly increased over previous decades. In fact, the small supply of the professional positions in academia compared to the growing number of postdoctoral researchers makes it difficult to find tenure-track positions. In 2008, the proportion of postdoctoral researchers who got a tenure or tenure-track position within 5 years after they received a doctoral degree was about 39%; nearly 10% of postdoctoral researchers were over 40 years old in 2003weblink {{webarchive |url=https://web.archive.org/web/20120323153949weblink |date=23 March 2012 }}{{full citation needed|date=September 2018}}{{full citation needed|date=September 2018}}On the other hand, 85 percent of engineering doctoral degree holders are likely to initially go into business or the industry sector.WEB,weblink Pathway Through Graduate School and Into Careers, Under the circumstances, providing doctoral students as well as postdoctoral researchers with necessary skills for nonacademic positions has become one of the important roles for graduate schools and institutions.
