We do realize that the ability to make meaningful decisions and solve problems effectively is based on both skill and experience. We therefore recognize that any level of accreditation needs to embody a combination of skills acquired through training and the application of training within the work environment. The accreditation is not based on any specific problem-solving methodology. The requirement is that candidates must be able to demonstrate their ability to determine the reason/cause for a simple problem and also to recommend a realistic solution for the same scenario.
