The use of web‐based education has increased significantly. As a result there is a need to focus on methods, employed to evaluate teaching and learning outcomes, when technology is used to enhance learning. This chapter provides an overview of what, how, and why to assess, test and measure learning. The use of technology facilitates a combination of different perspectives within an evaluation process. Not only the knowledge and skills of students but also the learning arrangements are the focus of assessment. Evaluation generates information which can be used for different purposes e.g. planning, implementing and guiding teaching and learning processes timely and for the future as well. Based on experiences of teaching health informatics, an evaluation model for web‐based courses is described. The risks of dishonesty and misbehavior related to web‐based education are recognized.
