Degrees in mechanical engineering are offered at various universities worldwide. Mechanical engineering programs typically take four to five years of study depending on the place and university and result in a Bachelor of Engineering (B. Eng. or B. E. ), Bachelor of Science (B. Sc. or B. S. ), Bachelor of Science Engineering (B. Sc. Eng. ), Bachelor of Technology (B. Tech. ), Bachelor of Mechanical Engineering (B. M. E. ), or Bachelor of Applied Science (B. A. Sc. ) degree, in or with emphasis in mechanical engineering. In Spain, Portugal and most of South America, where neither B. S. nor B. Tech. programs have been adopted, the formal name for the degree is "Mechanical Engineer", and the course work is based on five or six years of training. In Italy the course work is based on five years of education, and training, but in order to qualify as an Engineer one has to pass a state exam at the end of the course. In Greece, the coursework is based on a five-year curriculum and the requirement of a 'Diploma' Thesis, which upon completion a 'Diploma' is awarded rather than a B. Sc.
