What are the 11 types of the IQ Test?

One of the most important mental abilities that people are measured for is intelligence quotient or IQ. IQ is a score on a standardized test that is used to measure intelligence. IQ tests are often administered to children, but they can also be used to measure adults. This article will provide the 11 branches of IQ tests.

  • Stanford-Binet Intelligence Scale
  • Universal Nonverbal Intelligence
  • Differential Ability Scales
  • Peabody Individual Achievement Test
  • Wechsler Individual Achievement Test
  • Wechsler Adult Intelligence Scale
  • Woodcock-Johnson III Tests of Cognitive Disabilities
  • Raven’s Progressive Matrices

What is IQ?

IQ stands for intelligence quotient. It is a measure of the capacity of an individual to reason, plan, solve problems, think abstractly, comprehend complex ideas, learn quickly, and learn from experience. 

IQ is divided into three categories: verbal, mathematical, and spatial. The verbal IQ is the ability to understand language, including words, sentences, and paragraphs. 

The mathematical IQ is the ability to understand numbers and symbols such as fractions and decimals. The spatial IQ is the ability to understand images and shapes.

IQ is a score based on a standardized test that is used to measure human intelligence. IQ is usually measured using a scale of 100-160.  IQ tests are also used to evaluate the intelligence of animals, such as dogs and horses.

Although IQ tests are typically used to determine educational placement, they are also used to help diagnose learning disabilities and other intellectual disabilities.

Stanford-Binet Intelligence Scale

The Stanford-Binet Intelligence Scale is an individually administered measure of intelligence. The test is scored on a scale from 0 to 160 and it has a standard deviation of 15. 

The test consists of multiple verbal subtests, including vocabulary, comprehension, arithmetic, and reasoning, as well as a performance subtest. 

The Stanford-Binet Intelligence Scale can be used for a variety of purposes, including assessment, counseling, and remedial programs. 

Universal Nonverbal Intelligence

The Universal Nonverbal Intelligence Test (UNIT) is a collection of nonverbal intelligence tests. These tests have been developed to help determine people’s intelligence in the absence of verbal or written language. 

The test consists of 14 different tests that are based on nonverbal intelligence, including emotional intelligence, personal and social intelligence, and spatial intelligence.

Differential Ability Scales

The Differential Ability Scales Test is a test used to measure how someone is able to identify and compare the difference between two things. For example, a person might be asked to identify the difference between a red and blue color. 

The Differential Ability Scales Test (DAST) is used to help diagnose learning disabilities such as dyslexia, dyscalculia, and dysgraphia. The test consists of eight subtests that are designed to measure the following skills:

Peabody Individual Achievement Test

The Peabody Individual Achievement Test is a test that measures cognitive skills and is designed to be completed by students in grades three through eight. 

It is one of the most widely used tests in the United States and it is given to measure students’ abilities in math, reading, and writing. The Peabody Individual Achievement Test is a series of tests that measure a student’s ability to think critically and solve problems. 

It is composed of four tests that are given in different subjects. These tests have been around since 1947, and it is still one of the most popular standardized tests for students.

Wechsler Individual Achievement Test

The Wechsler Individual Achievement Test (WIAT) is a standardized intelligence test used to assess a child’s general cognitive ability and achievement. 

It is the most widely used intelligence test in the United States. It is given to children between the ages of 6 and 16 years old. The test consists of a number of subtests, including vocabulary, block design, object assembly, matrix reasoning, picture completion, digit span, digit symbol substitution, and similarities. 

The WIAT is typically administered by a psychologist or school administrator. The WIAT is also often used to assess the cognitive abilities of people who have been diagnosed with intellectual disabilities or developmental disorders.

Wechsler Adult Intelligence Scale

The Wechsler Adult Intelligence Scale (WAIS) is a widely used intelligence test designed to measure the intellectual functioning of adults and older adolescents. 

The WAIS-III is a revision of the WAIS-II, and it was first published in 1987. It is typically used in clinical and educational settings. The WAIS-III is composed of several subtests that cover a wide range of cognitive abilities, including working memory, processing speed, vocabulary, and perceptual organization. 

Woodcock-Johnson III Tests of Cognitive Disabilities

The Woodcock-Johnson III Tests of Cognitive Disabilities are a series of tests that assess your cognitive abilities. They are used to diagnose cognitive disabilities such as Attention Deficit Hyperactivity Disorder (ADHD), dementia, and Alzheimer’s disease. The test consists of tests such as the Boston Naming Test, Symbol Search, and Block Design.

Raven’s Progressive Matrices

The Raven’s Progressive Matrices is a test of cognitive ability. It is a nonverbal and self-paced test that measures fluid intelligence. The test is composed of three subtests: Similarities, Vocabulary, and Arithmetic. The test is widely used in research on fluid intelligence and personality traits.

Multidimensional Aptitude Battery II

The Multidimensional Aptitude Battery II is a personality test that assesses the different dimensions of personality and interests. The test measures the different abilities in six different areas. These areas are verbal reasoning, quantitative reasoning, perceptual speed, spatial ability, working memory, and fluid intelligence.

Reynolds Intellectual Assessment Scales

The Reynolds Intellectual Assessment Scales (RIAS) is a standardized test that is used to measure an individual’s intellectual functioning. 

There are five scales that can be used to measure intelligence, including verbal comprehension, perceptual reasoning, working memory, processing speed, and verbal fluency. The test is scored on a scale from 1-20, with higher scores indicating better performance.

Thurstone’s Primary Mental Abilities

Thurstone’s Primary Mental Abilities is a test that measures intellectual ability in children between the ages of 3 and 16. The test consists of two parts, one is the Primary Mental Abilities Test, which measures general intelligence, and the other is the Primary Mental Abilities Test-Revised, which measures specific abilities. The tests have been used to identify gifted children in the past.

Conclusion

IQ or intelligence quotient is a score derived from an individual’s ability to perform mental tasks such as reasoning, comprehension, memory, and problem-solving. IQ is typically measured with a standardized test called the Stanford-Binet Intelligence Scales. The Stanford-Binet Intelligence Scales is widely used because it is considered to be an unbiased and reliable measure of intelligence. IQ scores can be interpreted in a variety of ways, but they are typically categorized into three groups: low average, average, and high average. IQ tests can be a good indicator of how someone performs in school or work.
