Designing an assessment module may sometimes be more crucial than designing the eLearning course itself. This is because determining the objectives and takeaways of a module and testing learners to check if they can retain any of the takeaways is complex. Especially when the subject is vast with multiple levels of depth.
To begin with, you first must determine what your learners must understand or learn. Then you need to determine the level of their understanding or learning (how well do they know a topic). And finally, you must determine what percent of the training should the learner successfully retain in order to qualify.
