The test was developed with a stratified sample of 2,285 people aged 4 to 85. The WRIT is an attempt to optimize accuracy in a short-form IQ test that includes fewer subtests. Experts have historically argued that these shorter tests are less accurate. The popular shortening of IQ tests, especially those intended for children, is primarily due to the increasingly heavy workloads of school psychologists. The WRIT is one of many short-form IQ tests developed since the Wechsler-Bellevue scale, an early model for intelligence testing, was created. It is designed for easy administration among trained psychologists, which is accomplished using a hierarchical model that frequently occurs in psychological testing. The WRIT is intended to assess those aged 4 through 85. It was created alongside the Wide Range Achievement Test 3 (WRAT3), a measure of reading comprehension and academic ability, by Pearson Education in 2000. The test also involves only four subtests and requires fewer physical materials than a typical test. Running at approximately 30 minutes, the WRIT is shorter than traditional IQ tests. The Wide Range Intelligence test (WRIT) is an assessment of verbal ( crystallized) and visual ( fluid) IQ. This article may need to be rewritten to comply with Wikipedia's quality standards.
