Elicitation requires experts to make probabilistic judgements, such as median and quartiles, that are difficult and unfamiliar tasks for most experts. Training is always given in a SHELF workshop, but it takes time for experts to understand the judgements required and to make them reliably. The idea of the e-learning course is for experts who will take part in a SHELF elicitation workshop to get exposure to the kinds of judgements they will be required to make, before the workshop itself, and in a relaxed, self-paced way. The course takes about two hours to complete.
