The Wechsler Intelligence Scale for Children, or WISC, can be used for teenagers up to age 16 years and 11 months. The WISC is generally used to evaluate school placement and to identify children for school gifted programs or with mental limitations. Children and teenagers who take the WISC are compared with children in the same age group for consistency. Verbal and performance skills are tested over a period of 50 to 75 minutes, with tests measuring vocabulary, arithmetic, comprehension, picture arrangement, coding and mazes. A score of 100 on the WISC is considered "average" intelligence.
The Stanford-Binet Intelligence Test can be used for teenagers up until mature adulthood. Like the WISC, the Stanford-Binet is generally used to evaluate school placement, giftedness or mental limitations. The Stanford-Binet test is administered by a psychologist in a school or clinical setting. The test is about 45 to 90 minutes in length, depending on the age of the participant. Four areas of intelligence and cognition are reviewed: verbal, visual and quantitative reasoning skills, as well as short-term memory. Scores are compared against the standard age score for the teenager's chronological age. As with the WISC, a score of 100 is considered average.
The Scholastic Aptitude Test, or SAT, is used to measure a teenager's skill level for the purpose of college admissions. Divided into three main sections, the SAT tests a teenager's reading, writing and arithmetic skills. The test is given over a three and a half hour time period. Scores are calculated for each section on a scale of 200 to 800, with 500 being average. A percentile ranking is given along with the score, indicating how well you did compared to other test-takers. The SAT can be taken more than one time to increase your score and chances of being accepted to your ideal college.
The Wonderlic IQ test is used to measure the intelligence of prospective employees or team members. The Wondelic IQ test measures verbal, spatial and numerical reasoning skills. The test has been deemed a quick IQ test, since in generally takes around 15 minutes to complete. The person administering the test does not have to have any special training. The Wonderlic IQ test has been used since 1970 to test the potential of prospective players in the National Football League. A score of 20 or more indicated average intelligence and potential success in job and social skills.
Culture Fair Intelligence Tests were developed to assist people with limitations from being unfairly labeled. Developed in 1920 by Raymond B. Cattell, the CFIT measures non-verbal abilities, such as reasoning and analysis. The CFIT uses mazes, pictures and other classifications believed to be consistent over all cultures. CFIT consists of three scales, with scales two and three used for teenagers. The CFIT scores have been shown to correlate with the scores of the WISC, Stanford-Binet and other general intelligence tests.
