Definition of Assessment: In psychology, assessment refers to the process of collecting and evaluating information about an individual's psychological attributes, such as intelligence, personality, aptitude, or psychopathology. It aims at understanding a person’s psychology, in order to make diagnoses, or to plan treatments.
Use of Multiple Methods: The assessment process often involves using multiple methods, such as tests, interviews, observations, and case studies, to get a complete understanding of the person.
Comparison to Standards: Evaluation is done using different methods by comparing the gathered information against specific standards or norms. This provides context to the data and allows to draw interpretations.
