The early years (1934 -1947) were the years of Yaba Higher College on the same grounds now occupied by Yaba College of Technology. The moving out to Ibadan of the Higher College to form University college Ibadan in 1948 saw the use of the premises vacated becoming Yaba Technical Institute.
Yaba Technical Institute then took on a national assignment of training engineering assistants for various Government Departments in Nigeria.

The courses run at Yaba Technical Institute were then essentially of three types, namely:
Technical, which meant technician courses in Building, Civil, Mechanical and Electrical Engineering.
Commercial for business oriented courses and printing courses for personnel of government in various printing trades.

In this array of courses, the technical courses formed the core of the Institute with others as periphery. These technical courses were therefore the humble beginnings of Engineering on the Campus.
During those days, there were not more than twenty four (24) students admitted into each major course, and almost all the staff was British. The students were then prepared for external examinations of the City and Guilds of London Institute.

Eventually in 1963, the Technical Institute again changed name to become Yaba College of Technology. By this time, all courses had expanded and two Engineering Departments existed, namely:
1. Civil Engineering
2. Mechanical and Electrical Engineering

By 1970, two departments mentioned above had grown into three: Department of Civil Engineering. Department of Mechanical Engineering and Department of Electrical Engineering.

By 1981, further growth occurred occasioned by the beginning of the School System which saw Yaba College of Technology having five Schools: School of Applied Sciences, School of Art, Design and Printing Technology, school of Engineering, School of Environmental Studies and school of Management and Business Studies. Engineer A. A. Fashina was the first director of the School of Engineering.

The School of Engineering is primarily designed to train able manpower as technicians and technological engineers who are:

1. To install, commission, operate, use, maintain, oversee, supervise and manage engineering plants, systems and projects.
2. To supervise various engineering staff.
3. To evolve and modify designs of plants and projects
4. To engage in various creative engineering endeavours.
5. To acquire various technical skills and theories relevant to their various disciplines.
6. To acquire management skills that can orientate them towards various industrial businesses and other employment climates.
7. To inculcate in them good conduct expected of responsible citizenry.

From the yearly admission population of twenty four (24) students in the fifties, the school now admits not less than five hundred (500) students into its various courses annually. It could in fact admit much more except for the constraints of physical space. The following courses are offered in the School of Engineering:

1. National Diploma (ND) Courses in Civil, Electrical, Mechanical, Computer, Metallurgical, Industrial Maintenance, Marine, Welding and Fabrication and Agric & Bio-Environmental Engineering.
2.Higher National Diploma (HND) Courses: These are for candidates with National Diploma and with at least one year relevant industrial experience. Higher National Diploma courses are available in the following fields: Civil Engineering, Mechanical Engineering with options in main factory Engineering, Power Plant Engineering and Electrical/Electronics Engineering with options in either Electrical Power (i.e. heavy current) and Electronics also called light current, Industrial Maintenance Engineering, Metallurgical Engineering and Computer.

All the ND and HND courses mentioned above have been duly accredited by the National Board for Technical Education (NBTE). Since the inception of the College, the various Departments of Engineering have produced distinguished men and women who have made their marks in Engineering and allied fields. Amongst these are university professors, senior engineers, distinguished architects, surveyors and builders as well as soldiers.

The achievements of the School are largely based on an elegant mix of theory and practices.
In the years ahead, projections are as follow:
1. To start Higher National Diploma Courses in Marine Engineering, and Instrumentation Engineering. Proposals for these are being studied by the Academic Programmes Implementation Committee (APIC) of the College for tidying up of details before being proposed to the College Government Council for ratification.
2. To start National Diploma and licentiate programmes in Aircraft Maintenance Engineering. For this, approval is needed from the College Government Council and clearance not only from NBTE but from the Ministry of Aviation and the Air Registration Board. Also Chemical Engineering and Mechatronics Engineering programmes are up-coming.
3. To start a programme in general maintenance engineering and high quality engineering fabrication.

This programme is to be in three phases namely: Machine Welding Maintenance: Machine Maintenance: Electrical, Electronic and Computer Maintenance. Maintenance Engineering Programme is a technical assistance programme of the French Government. Its expected advantage is in high quality fabrication repair and maintenance of various items of equipment.
The first phase of the Welding Centre programme was scheduled to take off on April 26, 1989. By September 1989, five (5) members of staff of Yaba College of Technology were trained in French for the various welding processes. Two French experts were in Nigeria to see to the successful take off. All necessary equipment are already installed and in full swing and usage. These equipments include: Metal Inert Gas (MIG) sets, Tungsten Inert Gas Welding (TIGW), and Plasma cutting sets, etc.

In terms of further education, the school of Engineering also intends to float post HND programmes and some courses for various cadres of Engineering Personnel. It intends to help the College to generate revenue by services that its various workshops/laboratories can offer the nation by means of consultancy services. Such revenue yielding (commercial) activities will, no doubt, help to put the equipment to greater practical use, and, in addition, stimulate the primary assignments for training the students.

The School of Engineering has the following departments.

1. Mechanical Engineering
2. Industrial Maintenance Engineering
3. Electrical and Electronics Engineering
4. Computer Engineering
5. Mechatronics Engineering
6. Welding and Fabrication Engineering
7. Metallurgical Engineering
8. Civil Engineering
9. Marine Engineering
10. Chemical Engineering
11. Agricultural and Bio-Environmental Engineering
12. Mineral and Petroleum Resources Engineering
