Wide Range Intelligence Test

The WRIT is one of many short-form IQ tests developed since the Wechsler-Bellevue scale, an early model for intelligence testing, was created. The popular shortening of IQ tests, especially those intended for children, is primarily due to the increasingly heavy workloads of school psychologists. Experts have historically argued that these shorter tests are less accurate. The WRIT is an attempt to optimize accuracy in a short-form IQ test that includes fewer subtests. The test was developed with a stratified sample of 2,285 people aged 4 to 85. The test was published by British testing company Pearson in 2000; its manual was written by Joseph Glutting, Wayne Adams, and David Sheslow. == Method ==

The WRIT begins with a visual subtest involving matrices. These are followed by verbal analogies, visual diamonds, and a vocabulary test. Specific administration and starting points are determined by age range. Matrices In the first portion of the test, examinees are given a limited amount of time to select an image that satisfies a relationship in a series of images. Matrices are typically a series of shapes with implied relationships in shape, shading, or transformation. This subtest is nonverbal and is completed on an easel. Verbal Analogies This test is administered verbally. The examiner provides a statement such as "A cat to a kitten is a dog to a ___." The examinee is asked to complete this statement. Verbal analogies are used to determine verbal, crystallized intelligence and demonstrate an understanding of oral language. There is no visual element to this subtest, and pronunciation guides are not provided for the administrator. Visual Diamonds Under a specified time limit, the examinee is asked to reproduce two- or three-dimensional patterns using diamond-shaped cardboard chips. This test is intended to require low physical dexterity and focus on higher spatial understanding and visual manipulation skills. The test is presented in easel format with no verbal element except initial instructions. Vocabulary Test In the vocabulary test, the examinee defines words given by the examiner. The test has no visual elements. Unlike the verbal analogies subtest, the vocabulary test provides a pronunciation guide for more difficult words. == Effectiveness and criticism ==

Standardization The standardization of the WRIT is generally deemed effective in regards to demographics. The test was developed with a demographic sample based on the 1997 U.S. census. Though some aspects of this sample are generally considered adequate, experts have criticized these trials due to educational discrepancies in some age groups. In young adult demographics, individuals with college educations were overrepresented. This has caused speculation of possible inaccuracy in the WRIT scale. Many experts also agree that the test would benefit from more extensive standardization research due to limitations in its initial trials. == References ==
