A Bachelor of Engineering (BE or BEng) or a Bachelor of Science in Engineering (BSE) is an academic undergraduate degree awarded to a student after three to five years of studying engineering at an accredited college or university.
In the UK, a B.Eng. degree will be accredited by one of the Engineering Council's professional engineering institutions as suitable for registration as an incorporated engineer or chartered engineer with further study to masters level. In Canada, a degree from a Canadian university can be accredited by the Canadian Engineering Accreditation Board (CEAB). Alternatively, it might be accredited directly by another professional engineering institution, such as the US-based Institute of Electrical and Electronics Engineers (IEEE). The B.Eng. contributes to the route to chartered engineer (UK), registered engineer or licensed professional engineer and has been approved by representatives of the profession.
Most universities in the United States and Europe award the Bachelor of Science Engineering (B.Sc.Eng.), Bachelor of Engineering (B.Eng.), Bachelor of Engineering Science (B.Eng.Sc.), Bachelor of Science in Engineering (B.S.E.) or Bachelor of Applied Science (B.A.Sc.) degree to undergraduate students of engineering study. For example, Canada is the only country that awards the B.A.Sc. degree for graduating engineers. Other institutions award engineering degrees specific to the area of study, such as B.S.E.E. (Bachelor of Science in Electrical Engineering)  and B.S.M.E. (Bachelor of Science in Mechanical Engineering).
In French-speaking Canada, mainly Québec, the Bachelor of Engineering is referred to as B.Ing (Baccalauréat en ingénierie).
A less common and possibly the oldest variety of the degree in the English-speaking world, is Baccalaureus in Arte Ingeniaria (B.A.I.), a Latin name meaning Bachelor in the Art of Engineering. Here Baccalaureus in Arte Ingeniaria implies excellence in carrying out the 'art' or 'function' of an engineer. Some South African universities refer to their engineering degrees as B.Ing. (Baccalaureus Ingenieurswese, in Afrikaans).
A Bachelor of Engineering degree will usually be undertaken in one field of engineering, which is sometimes noted in the degree postnominals, as in BE (Aero) or BEng (Elec). Common fields for the Bachelor of Engineering degree include the following fields:

In Australia, the Bachelor of Engineering (BE or BEng - depending on the institution) is a four-year undergraduate degree course and a professional qualification.
The title of “engineer” is not protected in Australia, therefore anyone can claim to be an engineer and practice without the necessary competencies, understanding of standards or in compliance with a code of ethics. The industry has attempted to overcome the lack of title protection through chartership (CPEng), national registration (NER) and various state registration (RPEQ) programs which are usually obtained after a few years of professional practice.
In Canada, degrees awarded for undergraduate engineering studies include the Bachelor of Engineering (B.Eng. or B.E., depending on the institution); the Baccalauréat en génie (B.Ing., the French equivalent of a B.Eng.; sometimes referred to as a Baccalauréat en ingénierie); the Bachelor of Applied Science (B.A.Sc.); and the Bachelor of Science in Engineering (B.Sc.Eng.).
The Canadian Engineering Accreditation Board (CEAB), a division of the Engineers Canada, sets out and maintains the standards of accreditation among Canadian undergraduate engineering programs. Graduates of those programs are deemed by the profession to have the required academic qualifications to be licensed as professional engineers in Canada. This practice is intended to maintain standards of education and allow mobility of engineers in different provinces of Canada.
A CEAB-accredited degree is the minimum academic requirement for registration as a professional engineer anywhere in the country and the standard against which all other engineering academic qualifications are measured. Graduation from an accredited program, which normally involves four years of study, is a required first step to becoming a professional engineer. Regulation and accreditation are accomplished through a self-governing body (the name of which varies from province to province), which is given the power by statute to register and discipline engineers, as well as regulate the field of engineering in the individual provinces.
Graduates of non-CEAB-accredited programs must demonstrate that their education is at least equivalent to that of a graduate of a CEAB-accredited program.
