In the October SAIRAC Johannesburg Centre online Tech Talk hosted by Air Conditioning and Refrigeration Academy (ACRA) owner Grant Laidlaw, the future of air conditioning and refrigeration training was a central theme. With the legacy trade tests already phased out since June 30, 2024, the discussion focused on the transitional landscape and emerging qualifications in the industry.
This is the transcript of the presentation, edited by Eamonn Ryan, and is Part 6 of a 9-part article.

Future trade testing process
Looking ahead, Laidlaw discussed potential changes to the Independent Trade Assessment (ISA) process, which aims to streamline qualification verification. The proposed system includes an advocacy phase to ensure all documentation is correct, followed by a technical panel evaluation of a portfolio of evidence.
This segment highlighted the complexities and bureaucratic hurdles in the current qualification and trade testing landscape, underscoring the need for clearer pathways and streamlined processes to better prepare apprentices for successful careers in the refrigeration and air conditioning industry.
The trade testing process typically involves an assessor, a moderator, and, if necessary, a subject matter expert. Candidates undergo an interview and evaluation to provide feedback on their readiness for testing. An upcoming addition is a theoretical test, which may take place at a TVET college rather than a trade center, though specifics are still unclear.
If the interview outcome is favourable, candidates will proceed to the ISA trade test. If not, they may need to address gaps in their experience, particularly in areas like electrical work, through accredited training from skills development providers or workplace training centers. The knowledge assessment, practical assessment, and workplace evaluation form part of the Recognition of Prior Learning (RPL) toolkit, which is still under development by NAMB.
External Integrated Summative Assessment (EISA)
The EISA, or external integrated summative assessment, will lead to the issuance of an occupational certificate. This assessment spans three days, incorporating both theoretical and practical components. Candidates must present a portfolio of evidence that includes knowledge questionnaires and practical observation checklists. While the training provider manages the theoretical components, workplaces need to maintain logbooks that document all qualifications and competencies achieved.
The new structure introduces four distinct trade tests, expanding from the previous categories. The main trade test outcomes are:
- Air Conditioning and Refrigeration Mechanic: Covers central plant air conditioning, duct balancing, and air handling units. The associated tests will include generic knowledge and specialized air conditioning aspects
- Fluorinated and Flammable Refrigerants: This includes both theoretical and practical components, focusing on the relevant safety and technical skills
- Carbon Dioxide Refrigerants: Similar structure to the fluorinated category, with specific attention to CO₂ plant and equipment
- Ammonia Refrigeration Mechanic: This includes practical testing on ammonia plants, with insights from industry experts to ensure the test meets international standards. The new assessment will be more comprehensive than previous tests, expanding from 12 tasks to around 25, providing a broader scope of evaluation
