I have been asked this again. In short the answer is maybe, it depends, but it is not recommended.

ISO 18436 does make allowances for previous learning and permits people to move directly to Level 2 in certain circumstances. Every case is really assessed individually. It is likely that if you recently completed a degree that had a strong emphasis on heat transfer then it might be permitted if you had also gained a lot of thermography experience. Otherwise the answer is really NO. In my experience, people that have tried to move directly to Level 2 really struggle with the exam, and find it an extremely difficult course. I have never met anyone that did Level 2 directly and found it easy. I do not recommend this to people even though they might consider their own knowledge and experience to be sufficient, as it is the case that most people overestimate their own knowledge, and underestimate the difficulty of Level 2 thermography courses.
