part of the process x?". Because all answers but one name correct steps the performer obtains a maximum of correct information - an essential design principal to transfer knowledge by the assessment itself. For each question a "negative feedback" (in case the selected answer is not correct) additionally refers to the source of knowledge - in order to enforce the impression that the required information for a correct answer is available effortless. For each question a "positive feedback" confirms and amplifies the gained knowledge. Efficiency and efficacy The efficiency of a Knowledge Transferring Assessment results from the combination of knowledge transfer together with the knowledge assessment and thereby with the minimization of the required training effort. Specifically individuals with a certain level of know-how and knowledge benefit from the approach. The independency of location, time, mobility, resource availability, etc. are e-Learning benefits and advantages in general and Online assessments specifically. The efficacy depends on: The relevance and completeness of the assessment questions. The form of the assessment questions which must enable to provide a maximum of relevant knowledge (only one answer amongst may is garbage). The online availability of both, the assessment itself and all required knowledge material The coherence between the assessment questions and the structure and design of the knowledge material and its coherence.. Secondary (general) design principals The below are considerable properties of an Online Assessment. However, they are depending on the used authoring tool. Which of the properties and features is given a certain value should be part of the tool selection process. Many of the below properties increase the value of the tool and thus finally also the value of the provided Knowledge Transferring Assessment. The Assessment itself does not store any user relevant data and thus provides no conflicts with any data privacy rules. As a result, an assessment has to be finished within one session The final result is presented with the answer of the last question. The result indicate how many question had been answered correctly and/or how many points of a possible maximum had been reached. Only the first chosen answer counts for the result and secondary choices are impossible. I.e a trial and error approach is impossible not even to find out the correct answer for a subsequent performance. Each assessment start not only presents the questions in a random order but also the answers belonging to a question. Thus
