Maintenance skills and retention: what the pipeline is producing
The constraint on maintenance performance in this region is increasingly people, not systems. The training data explains why, and it is not encouraging.
- Vocational programmes accounted for 1.8% of lower-secondary enrolment in sub-Saharan Africa, and under 15% at upper secondary. [1]
- Vocational enrolment declined at both levels between 2000 and 2022. [1]
- In South Africa, the share of firms struggling to recruit artisans rose from 10% in 2024 to 22% in 2025. [2]
- The ILO-recommended mix is one engineer to five technicians to twenty-five craftspeople; actual African skill-mix data is seriously lacking. [3]
Every maintenance improvement discussed in this series assumes someone competent to carry it out. That assumption is getting harder to make, and the reason is visible in enrolment statistics rather than in anything specific to maintenance.
What the pipeline looks like
Official statistics put vocational programmes at just 1.8% of total enrolment at lower-secondary level in sub-Saharan Africa, against 3.4% in North Africa, with several countries offering no vocational option at that level at all. At upper-secondary level, fewer than 15% of students in sub-Saharan Africa were enrolled in vocational education, compared with 31.2% in North Africa. Enrolment declined at both levels between 2000 and 2022. [1]
The picture inverts at post-secondary non-tertiary level, where 84.7% of students across twenty-seven countries were in vocational programmes, and in twenty-one of those countries all students at that level were. [1] Technical training is happening, but late and in a narrow channel.
What employers report
The sharpest employer data comes from South Africa, and applies to South Africa — we flag that rather than generalising it. The share of companies struggling to recruit artisans more than doubled in a year, from 10% in 2024 to 22% in 2025, with electricians, millwrights, fitters and instrumentation technicians hardest to fill. The average artisan is reported to be in their mid-fifties. Even at its peak, throughput on the National Certificate (Vocational) at technical colleges reached 14% in 2024, with most of the 2.6 million students who entered over five years dropping out or falling behind. [2]
Those four trades are precisely the maintenance trades. An ageing artisan population with a 14% training throughput is a maintenance capacity problem before it is an education problem.
The structural picture
Reviewing engineering capacity in sub-Saharan Africa, the World Bank cited the ILO-recommended ratio of one engineer to five technicians to twenty-five craftspeople, and noted that data on the actual skill mix across African countries is seriously lacking. [3] A joint African Development Bank and ILO study surveying sixteen countries, including Kenya, Tanzania and Zambia, found technical and vocational systems struggling to meet labour-market demand for want of effective links between training institutions and industry. [4]
Context from Uganda illustrates the labour market these systems feed: an ILO country report put the informal sector at 91% of employment, while the World Bank has estimated sub-Saharan Africa needs 25 million new jobs a year to keep pace with its labour force. [5] Formal technical employment is a small channel in a very large flow.
What an employer can actually do
- Assume you are training, not hiring. Budget for it as an operating cost rather than treating each vacancy as a recruitment event.
- Write down what your experienced technicians know, in the maintenance record, while they are still employed — the average artisan being in their mid-fifties is a documentation deadline.
- Design work so competence is not a prerequisite for a correct record: short forms, structured checklists, photographs, offline capture.
- Build relationships with a specific technical college rather than with the training system in general; the AfDB and ILO finding is that the missing element is the link, not the institution. [4]
- Measure retention as a maintenance KPI. Turnover in a maintenance team shows up eighteen months later as asset history nobody can interpret.
The systems argument follows from the workforce argument rather than replacing it. Where competence is scarce and mobile, the case for keeping maintenance knowledge in a shared record rather than in individual heads stops being an administrative preference and becomes a continuity requirement.
