The Bachelor of Engineering , abbreviated as B.E. , B.Eng. , or B.A.I. (in Latin form) is an undergraduate academic degree awarded to a student after four to five years of studying engineering at an accredited 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 a incorporated engineer or chartered engineer with further study to masters level. In Canada the degree from a Canadian university can be accredited by the CEAB. Alternatively, it might be accredited directly by another professional engineering institution, such as the U.S based Institute of Electrical and Electronics Engineers (IEEE). The B.Eng is mainly a route to chartered engineer, registered engineer or licensed professional engineer , and has been approved by representatives of the profession.
A B.E. has a greater emphasis on technical engineering aspects, for example, electronics and electrical circuits, than the B.Sc. However, topics covered in B.E. can overlap with B.Sc.
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 BSME (Bachelor of Science in Mechanical Engineering). 
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 an excellence in carrying out the 'art' or 'function' of an engineer. The degree is awarded by the University of Dublin (its Trinity College Dublin has had a School of Engineering since 1841), and also by the constituent universities of the National University of Ireland (N.U.I.), but in everyday speech it is more commonly referred to as Bachelor of Engineering , and the N.U.I. graduates also use the post-nomials translated into English, B.E., even though the actual degree and its parchment is in Latin.
Some South African Universities refer to their Engineering degrees as B.Ing. ( Baccalaureus Ingenieurswese - Afrikaans).

In Australia , the Bachelor of Engineering (BEng) is a four-year undergraduate degree course and a professional qualification. It is also available as a six-year sandwich course (where students are required to undertake a period of professional placement as part of the degree) or an eight-year part-time course through some universities. The Institution of Engineers, Australia ( Engineers Australia ) accredits degree courses and graduates of accredited courses are eligible for membership of the Institution. Bachelor of Engineering graduates may commence work as a graduate professional engineer upon graduation, although some may elect to undertake further study such as a Master's or Doctoral degree. Chartered Professional Engineer (CPEng) status or the various State registration requirements are usually obtained in later years. Graduates with formal engineering qualifications in Australia are often referred to as Professional Engineers to distinguish them from other professions where the term "Engineer" is used loosely.
In Bangladesh there are two types of degree are offered in University. One is Bachelor of Science in Engineering B.Sc(Engg) and another is Bachelor of Science on Engineering subjects B.Sc. (Honors). these are four year under-graduation university degree.Eligibility for entry is 12 years of school education under science background. Generally the first year (first two semesters) is common to all branches, and has the same subjects of study. Courses divert after first year. The medium of instruction and examination is English. Generally, universities in Bangladesh offer engineering degree in the following branches: Civil Engineering , Mechanical Engineering , Electrical & Electronics Engineering , Mechatronics Engineering , Electrical and Telecommunication Engineering, Industrial and Production Engineering , Computer Science & Engineering , Information & Communication Engineering, Material Science & Engineering, Nuclear Engineering , Petroleum & Mining Engineering, Applied Chemistry & Chemical Engineering, Textile Engineering , Glass & Ceramic Engineering, Aeronautical Engineering , Production Engineering , Biomedical Engineering , Genetic Engineering , Food engineering and Agricultural Engineering . The Ministry of Education , the UGC and the Government of Bangladesh are responsible for approving engineering colleges and branches/courses. Only those universities which have been approved by these bodies can award degrees which are legally valid and are accepted as qualifiers for jobs in the government and in the private sector.
In Canada , degrees awarded for undergraduate engineering studies include: the Bachelor of Engineering (B.Eng. or B.E., depending on the institution); 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. 
In Germany , the Bachelor of Engineering was introduced as part of implementation of the Bologna process . However, this degree is in fact mostly offered by German Fachhochschule -institutions Universities of Applied Sciences . German technical universities award a Bachelor of Science in engineering rather than the BEng degree.
The situation is similar in Finland as in Germany. Universities of applied sciences ( ammattikorkeakoulu ) grant professional bachelor's degrees ( insinööri (amk) ). The degree does not traditionally prepare for further study, but due to the Bologna process, a completely new degree of ylempi insinööri (yamk) has been introduced for engineers who wish to continue studying after some work experience. Before 2005, academic universities (see Education in Finland ) did not make an administrative distinction between studies on the Bachelor's and Master's level, and the Master's level diplomi-insinööri was the first degree to be received. Due to the Bologna process , an intermediate "Bachelor of Science in Engineering" ( tekniikan kandidaatti ) has been introduced.
In Pakistan, Bachelor of Engineering (BE) or Bachelor of science in Engineering (BS/BSc Engineering) is a four years undergraduate professional university degree which includes the study of engineering courses and research. The prerequisite for this program is a two years FSc pre-engineering or a three years Diploma of Associate Engineer (DAE) in specific fields e.g. Chemical Engineering, Electronics Engineering, Electrical Engineering, Mechanical Engineering and Civil Engineering etc. Pakistan Engineering Council (PEC) accredits the undergraduate engineering degrees and regulates the engineering profession in Pakistan. PEC is a full signatory of Washington Accord .
In the Netherlands the Bachelor of Engineering was also introduced as part of implementation of the Bologna Process , the same as in Germany. The degree is only offered by Dutch Hogeschool -institutions and is equivalent to the Dutch engineer's degree "ingenieur" (ing.). A Dutch BEng involves a rigorous study of four years and is only awarded in the field of aeronautical engineering , mechanical engineering , software engineering , industrial engineering , or electrical engineering . Completion of a Dutch engineer's study in the field biochemical engineering , biomedical engineering , chemical engineering , environmental engineering , material engineering is however awarded with a Bachelor of Applied Science degree. Dutch technical universities award a Bachelor of Science in engineering (BSc) instead of the BEng degree.
In India, the Bachelor of Engineering degree is a professional engineering undergraduate degree awarded after completion of four years of engineering study and research. Institutes of national importance, like Indian Institute of Technology (IIT) and National Institute of Technology (NIT), offer Bachelor of Technology (B-Tech) degree since the courses they offer are exclusively engineering related. Some Indian universities, mainly private institutes which are affiliated to regional universities, offer engineering degree under the name of Bachelor of Engineering (B.Eng); but whichever name is used, the degree course follows the standard curriculum laid down by the All India Council for Technical Education (AICTE) and the University Grants Commission (India) (UGC).
In general Universities offer B Tech and colleges affiliated to Universities will offer as BE, however there is no difference in the programme objectives and learning outcomes of B.E or B.Tech. Eligibility for entry is 12 years of school education. Generally the first year (first two semesters) is common to all branches, and has the same subjects of study. Courses divert after first year. The medium of instruction and examination is English. Generally, universities in India offer engineering degree in the following branches: Civil Engineering , Mechanical Engineering , Electrical (and Electronics ), Electronics (and Communications or Telecom) Engineering, Instrumentation and Control Engineering, Computer Science Engineering , Information Technology , Chemical Engineering , Biotechnology Engineering , Metallurgical Engineering , Aerospace Engineering , Production Engineering , Systems Science , Biochemical Engineering , Biomedical Engineering , Genetic Engineering , Tool engineering and Agricultural Engineering . The AICTE , UGC and the Indian Government are responsible for approving engineering colleges and branches/courses. Only those universities which have been approved by these bodies can award degrees which are legally valid and are accepted as qualifiers for jobs in the central/state government and in the private sector.
In South Africa , the Bachelor of Engineering or Bachelor of Science in Engineering (BEng/BIng (for Afrikaans Universities) or B.Sc. Eng.) is awarded to a student who has completed four years course in engineering which consists of eight semesters. The degree is regulated by ECSA (Engineering Council of South Africa). In South Africa, the B.Tech is awarded by Universities of Technology and Comprehensive Universities - as distinct from Traditional Universities - and is generally practice or career oriented, as opposed to academically oriented. Relatedly, it is often offered in areas in which there is no corresponding B.Sc. or BComm (e.g. B.Tech: Forestry Management, B.Tech: Explosives Management ).
The degree is obtained after 4 years of study, and is usually offered as a 1-year programme, following completion of a relevant three-year National Diploma.
The B.Tech (often) carries the same points as other bachelor's degrees in terms of South Africa's National Qualifications Framework. At the same time, however, due to its orientation, it does not usually grant admission to the corresponding M.Sc. or MComm program, and students instead pursue the Master of Technology (M.Tech.) and Doctor of Technology (D.Tech.) degrees; it does grant admission to MBA programmes (see List of business schools in South Africa). In some cases, however, admission may be granted, once demonstrated that the student meets the necessary academic level to complete the requirements of the M.Sc or MComm.
