Around 20 % of PhD candidates drop out before the defence – Statistisk sentralbyrå data tracking cohorts from 2005 shows roughly one‑fifth have not completed a dissertation, while the number of outright rejected theses remains low [3][2].
Employment outcomes vary widely for non‑defenders – Among those who started a doctorate between 2005‑2015 and were still undisputed by 2021, about 25 % work in academia, 40 % in other sectors, and 33 % are outside Norway, many having emigrated [3].
Recent entrants face higher attrition – SSB’s December 2025 table indicates that 49 % of candidates who began a PhD contract in 2019 had not defended by the latest count [6].
UiO monitors at‑risk scholars with internal tools – Vice‑rector Mathilde Skoie says the decline in stipendiat numbers occurs before the defence stage and that the university uses employee‑talks and other measures for those on university contracts [1].
Other universities report similar pressures – NTNU pro‑rector Toril Nagelhus Hernes notes many candidates receive tempting industry offers mid‑programme, while Nord University pro‑rector Ketil Eiane says long‑standing candidates lacking progress are typically written out [1].
NIFU highlights funding and motivation gaps – The NIFU report stresses that qualified, motivated stipendiat are essential, points to challenges in maths, natural sciences and technology where industry pulls candidates away, and recommends a fourth‑year extension for those on schedule [7].
