Certainty-marked assessment is highly applicable to workplace learning. Whatever learning challenge you face, there is great value (for both organisations and learners) in understanding the level of knowledge held. Typical 10-question quizzes bolted onto the end of e-learning modules rarely provide a useful insight into learning.
If you would like to work with me on a corporate project that incorporates certainty-marked assessment (or indeed any corporate work) you will need to go through my daytime employer. You will get the benefit of a solution created and delivered by e-learning specialists to the exact requirements of your organisation.
