What is the difference between aptitude and achievement tests?
Aptitude tests are typically used in an effort to predict how well a person might perform in a school or employment situation. Aptitude tests tend to examine a broader range of knowledge and experiences than achievement tests, which usually only measure recent learning in specific subjects.
The Wechsler Individual Achievement Test–Third Edition (WIAT-III), an individually administered measure of oral language, reading, written language, and mathematics, is used in schools, clinics, private practices, and residential treatment facilities.
- The WIAT is an individually administered test that takes from 30 to 90mintes to administer. An achievement test measure how an individual is going in certain areas of academic school work. The WIAT gives a good overall summary of functioning in the following areas: reading, maths, written language and oral language.
- The test takes 45–90 minutes to administer depending on the age of the participant. The mean score for the WIAT-II is 100 with a standard deviation of 15, and the scores on the test may range from 40 to 160.

The IQ test consists of a number of tasks measuring various measures of intelligence including short-term memory, analytical thinking, mathematical ability and spatial recognition. Like all IQ tests it does not attempt to measure the amount of information you have learned but rather your capacity to learn.
- Genius IQ is generally considered to begin around 140 to 145, representing ~.25% of the population (1 in 400). Here's a rough guide: 115-124 - Above average (e.g., university students) 125-134 - Gifted (e.g., post-graduate students)
- Intelligence is the ability to think, to learn from experience, to solve problems, and to adapt to new situations. The intelligence quotient (IQ) is a measure of intelligence that is adjusted for age. The Wechsler Adult lntelligence Scale (WAIS) is the most widely used IQ test for adults.

Need for achievement (N-Ach) refers to an individual's desire for significant accomplishment, mastering of skills, control, or high standards. The term was first used by Henry Murray and associated with a range of actions. These include: "intense, prolonged and repeated efforts to accomplish something difficult.
- A theory proposed by David McClelland that describes how a person's life experiences changes individual needs over time. Classified into three groups; achievement, affiliation or power, these needs are shaped by the experiences of the individual.
- McClelland's Theory of Needs. In his acquired-needs theory, David McClelland proposed that an individual's specific needs are acquired over time and are shaped by one's life experiences. Most of these needs can be classed as either achievement, affiliation, or power.
- The Technical Definition. Goal-setting theory refers to the effects of setting goals on subsequent performance. Researcher Edwin Locke found that individuals who set specific, difficult goals performed better than those who set general, easy goals.
