Intelligence is the global capacity to understand the world, think rationally, and use available resources effectively when faced with challenges. Intelligence tests provide a global measure of a person's general cognitive competence including the ability to profit from schooling. Generally, students having low intelligence are not likely to do so well in school related examinations, but their success in life is not associated only with their intelligence test scores. Aptitude refers to an individual's underlying potential for acquiring skills. Aptitude tests are used to predict what an individual will be able to do if given proper environment and training. A person with high mechanical aptitude can profit from appropriate training and can do well as an engineer. Similarly, a person having high language aptitude can be trained to be a good writer. Interest is an individual's preference for engaging in one or more specific activities relative to others. Assessment of interests of students may help to decide what subjects or courses they can pursue comfortably and with pleasure. Knowledge of interests helps us in making choices that promote life satisfaction and performance on jobs. Personality refers to relatively enduring characteristics of a person that make her or him distinct from others. Personality tests try to assess an individual unique characteristics, whether one is dominant or submissive, outgoing or withdrawn, moody or emotionally stable. Personality assessment helps us to explain an individual's behaviour and predict how she will behave in future. Values are enduring beliefs about an ideal mode of behaviour. A person having a value sets a standard for guiding his actions in life and also for judging others.
