Diplomi-insinööri (DI) (Swedish: diplomingenjör) is a Finnish Master's level academic degree with a nominal length of 300 ECTS credits. The official English translation of the degree is Master of Science (Technology). The Finnish name derives from the old German degree called Diplom-Ingenieur. In both the new and the old system the degrees are classified into "pass" and "with distinction" (oivallisesti) categories. The rare "with distinction" classification (less than 10% of the graduates) requires a grade point average of at least 4.00/5 and a thesis with grade of at least 4/5.
