grade, used to identify which students are intellectually gifted. Students will need to be able to: "Follow directions, detect likenesses and differences, recall words and numbers, classify items, establish sequences, solve arithmetic problems, and complete analogies." The test consists of a mixture between verbal and non-verbal sections, helping inform the schools of the students "verbal, nonverbal, and quantitative ability" Raven's Progressive Matrices: The Raven's Progressive Matrices is a nonverbal test consisting of 60 multiple choice questions. This test is used to measure the individuals abstract reasoning, and is considered a nonverbal way to test an individuals "fluid intelligence." Stanford–Binet Intelligence Scales: By measuring the memory, reasoning, knowledge, and processing power of the user, this test is able to determine "an individual’s overall intelligence, cognitive ability, and detect any cognitive impairment or learning disabilities." This test measures five factors of cognitive ability, which are as follows: "fluid reasoning, knowledge, quantitative reasoning, visual-spatial processing and working memory." Wechsler Adult Intelligence Scale: The Wechsler Adult Intelligence Scale (WAIS) is used to determine and assess the intelligence of the participant. This is one of the more common tests used to test an individual's intelligence quotient. Throughout its history, this test has been revised multiple times since its creation, starting with the WAIS in 1955, to the WAIS-R in 1981, to the WAIS-III in 1996, and most recently the WAIS-IV in 2008. This test helps assess the level of the individuals verbal comprehension, perceptual reasoning, working memory, and processing speed. Wechsler Intelligence Scale for Children: The Wechsler Intelligence Scale for Children (WISC) is for children within the age range of six to sixteen years old. While this test can be used to help determine a child's intelligence quotient, it is often used to determine a child's cognitive abilities. First introduced in 1949, the WSIC is now on its fifth edition (WISC-V), and was most recently updated in 2014. Similar to the WAIS (Wechsler Adult Intelligence Scale), this test helps assess the level of the individuals verbal comprehension, perceptual reasoning, working memory, and processing speed. Wechsler Preschool and Primary Scale of Intelligence: The Wechsler Preschool and Primary Scale of Intelligence (WPPSI) is used to assess the cognitive ability of children ages two years and six months old to seven years and seven months old. The current version of the test is the fourth edition (WPPSI-IV). Children between the ages of two years and six months old,
