Engineering (Mechanical) Diploma

Full TimePart Time

Mechanical Engineers design and develop power-producing and power-using machinery, from simple mechanisms to more complex machines. They are also involved in operating and maintaining them. These machines include electric generators, internal combustion engines, steam and gas turbines, and refrigeration and air-conditioning systems. Mechanical engineers also design machines inside buildings, such as elevators and escalators.

Using an understanding of core concepts such as kinetics and thermodynamics (the application of heat and mechanical power), Mechanical Engineers are able to create this wide variety of machines and analyse mechanical processes to suit and sustain the manufacturing and operating goals of an organisation.

The UniCollege difference

  • A minimum of 40 contact (face-to-face) hours for each full-time subject and 36 contact hours for each part-time subject
  • At UniCollege, you can study an additional 5th subject each year if you are a full-time student
  • A workplace readiness programme before each level

Accreditation and Certification

Students write national examinations which are set and administered by the DHET. Successful students achieve the following certification which is conferred and issued by the DHET:

  • National Certificate: N4 Engineering Studies (SAQA ID: 66881)
  • National Certificate: N5 Engineering Studies (SAQA ID: 66960)
  • National Certificate: N6 Engineering Studies (SAQA ID: 67005)

Once you have successfully achieved all three N4-N6 certificates and have worked for 2 years (minimum of 2 670 hours) in an engineering environment, your logbook will be submitted to the DHET.

On receiving DHET approval, you are awarded the highly respected National N Diploma: Engineering Studies (SAQA ID: 67043).

Entrance Requirements
