Abstract: Skill is a task-specific ability that is influenced by task demands to achieve a task proficiently. Motor skills consist of both movement and interactions as an observable, goal-directed action and have a sequence that constitutes a routine. While skills are performed in a routine sequence, they are linked together by individualized habits. The assessment of skills has significant importance because, as with skills, task demands and physical and social environment can affect habits. Motor skills may be evaluated with non-standardized and standardized methods. Nonstandardized methods are informal evaluation based on observation of the performing of any task. After the observation is completed, the relevant motor skill is investigated carefully and systematically. Standardized methods are objective and well documented. This chapter aims to explain this wide variety of evaluation methods.
