Driver education in some countries has recently come to include drivers' risk awareness and evaluation of their own knowledge and abilities instead of focusing only on drivers' knowledge and abilities, measured by tests or expert judgements. Drivers' selfassessment has also been in focus in a new curriculum for driver education in Sweden. When this new curriculum is introduced, the driving-license test will have to be altered according to the new goals of the curriculum and new strategies for measuring drivers' self-assessment have to be employed. There is limited knowledge of how self-assessment of driver competence should be measured. Therefore, the overall purpose of this literature study was to examine how self-assessment in general is measured in different fields. In addition, the purpose was to investigate how self-assessments of driver competence have been measured and also whether the methods used for self-assessment in general and for self-assessment of driver competence could be applied to the driver education system in order to measure the goals of the curriculum.
