Electrotechnics N4: where the marks actually are
Knowledge and skills used in the electrical industry — solving electrical problems and working to safety standards. The entry subject of the Electrotechnics ladder.
N4 is being phased out. DHET is closing the NATED Report 191 programmes and replacing them with occupational qualifications. Its teach-out schedule (DHET TVET Circular TC 0134, 24 July 2025) gives the last national N4 examination for Engineering Studies as Trimester 2 2026. The last cohort gets a first sitting in Trimester 1 2026 and one repeat trimester — two chances, not the usual open-ended ones.
This is not a reason to stop. The National N Diploma can still be awarded up to 30 June 2029. Complete before 30 June 2026 and you receive the certificate exactly as now; after it, a DHET Statement of Results, which still counts toward the diploma. The Minister confirmed in June 2026 that qualifications already achieved stay valid and enrolled students should carry on.
Check your own dates with your college. The Department has since issued a revised circular, TC 0134(b), which it has not published, and further extensions were gazetted in June 2026 — so the date above is what DHET last put in writing publicly, not a promise about your intake.
What the exam is worth, module by module
These are DHET's own weight values. The syllabus states that a module's weight value gives the time to be spent teaching it and its share of the marks in the final exam — so this table is, in effect, the mark allocation of your paper. It totals 100.
| Module | Weight | |
|---|---|---|
| Principles of Electricity | 30 | |
| DC machines | 20 | |
| AC Theory | 20 | |
| Transformers | 10 | |
| AC machines | 10 | |
| Generation and supply of AC power | 5 | |
| Measuring Instruments | 5 |
How to spend your time
- Principles of Electricity alone is 30 marks — nearly a third of the paper, and the single heaviest module in any subject on this site. It is not optional.
- Principles, DC machines and AC Theory are 70 marks together. Secure those three and you are already past the pass mark before touching anything else.
- Generation and supply and Measuring Instruments are 5 each. Ten marks for two whole modules — revise them last, and briefly.
The paper is 100 marks in 3 hours — about 1.8 minutes a mark. If a question is worth 10 marks and you are 25 minutes in, you are losing marks elsewhere by staying on it.
Getting in
You need one of these:
- Completed National N3 certificate with Electrotechnology N3 or Electrical Trade Theory N3
- Passed Grade 12 with at least level 4 (50%, D symbol) in Mathematics and Natural Science or electrical subjects
- Completed NC(V) Level 4 in any engineering programme
- Passed senior certificate for adult learners with at least level 4 (50%, D symbol)
Full time: 7.5 hours per week. Also offered part time.
How you are assessed
Two things have to go right, and students lose the year on the first one more often than the second.
1. Your college (ICASS) mark
You need at least 40% to qualify to write the final exam at all. Your final mark is 40% college mark plus 60% exam, so what you do before the exam is 40% of the subject.
2. The final examination
3 hours, closed book, out of 100 marks. You pass at 40%.
- Your promotion mark is 40% of your ICASS mark plus 60% of your exam mark, so college work counts for two fifths of the subject.
- Scientific calculators are allowed. Programmable calculators are not.
