The Licentiate of Engineering is an intermediate postgraduate degree used only in a few countries, among them Sweden and Finland, and can be seen as an academic step halfway between a Master's and a PhD. In Swedish, it is called Teknologie Licentiat , usually abbreviated as Tekn. Lic. , and in Finnish, tekniikan lisensiaatti , abbreviated as TkL . The Licentiate of Engineering corresponds to 120 ECTS credits (80 workweeks (old credits)), or nominally two years of full-time work, whereas a PhD amounts to 240 ECTS credits (160 workweeks (old credits)), or a nominal period of four years of full-time work (one old credit equals one week of full-time studies). However, as a result of the differences in requirements and individual performance, the time to complete a Licentiate of Engineering degree varies. For the thesis, 2–3 peer-refereed articles (or an equivalent monograph) is usually required, and there is no requirement for original research per se . In contrast, a doctoral thesis requires 4–6 articles and must demonstrate original research.
