Validity Indicator Profile (VIP)
The Validity Indicator Profile (VIP) was originally designed as a measure of malingering to be used in the detection of intentionally feigned or grossly exaggerated neuropsychological symptoms. This use has been expanded to a general assessment of response style and is intended for use in cognitive testing. It provides a broad spectrum of information about an individual's performance on an assessment battery to indicate whether the testing should be considered representative of overall capacities. The VIP can be used with individuals between 18-69 years of age who are being evaluated or treated for cognitive difficulties. It is not recommended for use with individuals who have demonstrable mental retardation or severe cognitive impairment. When the VIP indicates that the test-taker's approach to the assessment was valid, the clinician can generally have confidence that the individual intended to perform well on the test and made a concerted effort to do so. When the VIP is invalid, there is the possibility that concurrently administered tests may underestimate the test-taker's actual ability. Published by Pearson Assessments. WWW.PEARSONASSESSMENTS.COM

Vineland Adaptive Behavior Scales
The Vineland Adaptive Behavior Scales is an assessment of personal and social sufficiency of individuals from birth to adulthood. The scales are applicable to handicapped and nonhandicapped individuals. The expanded form contains 577 items that is administered in semi-structured interview format with a parent or caregiver who is familiar with the child or low-functioning adult. The Vineland measures adaptive behavior in the communication, daily living skills, socialization and motor skills domains and each of their subdomains. In addition, there is an adaptive behavior composite and a maladaptive behavior domain. Published by American Guidance Service, Inc. AGS.PEARSONASSESSMENTS.COM

Wechsler Abbreviated Scale of Intelligence (WASI)
The Wechsler Abbreviated Scale of Intelligence (WASI) was developed to meet the demands for a short and reliable measure of intelligence in clinical, psycho-educational, and research settings. The WASI is individually administered and is designed for use with individuals aged 6 to 89 years. It is nationally standardized and yields the three traditional Verbal, Performance, and Full Scale IQ scores. The scale is also linked to the Wechsler Adult Intelligence Scale, Third Edition (WAIS-III) and the Wechsler Intelligence Scale for Children, Third Edition (WISC-III) and provides tables for estimating IQ score ranges on both the WISC-III and the WAIS-III.

Wechsler Intelligence Scales for Children-Fourth Edition (WISC-IV)
The Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV) is an individually administered clinical instrument for assessing the cognitive ability of children aged 6 through 16 years old. The WISC-IV provides subtest and composite scores that represent the individual's intellectual functioning. There are 15 subtests that are divided into four specific cognitive domains: Verbal Comprehension, Perceptual Reasoning, Working Memory, and Processing Speed. The Verbal Comprehension Index measures verbal abilities utilizing reasoning, comprehension, and conceptualization and the Perceptual Reasoning Index measures perceptual reasoning and organization. The Working Memory Index measures attention, concentration, and working memory and the Processing Speed Index measures the speed of mental and graphomotor processing. These domains are calculated into a composite score that represents general intellectual ability, the Full Scale IQ. Published by The Psychological Corporation. WWW.HARCOURTASSESSMENT.COM

Wechsler Preschool and Primary Scales of Intelligence-Third Edition (WPPSI-III)
The Wechsler Preschool and Primary Scale of Intelligence-Third Edition (WPPSI-III) is an individually administered clinical instrument for assessing intelligence of children aged 2 years 6 months through 7 years 3 months. There are two separate protocols which allow for an abbreviated administration for children under the age of 4 years. The WPPSI-III includes 14 subtests that are used to obtain three IQ scores: Verbal, Performance, and Full Scale and two additional composites: the Processing Speed Quotient and the General Language Composite. The Verbal IQ score is a measure of acquired knowledge, verbal reasoning, and comprehension of verbal information. The Performance IQ score provides an indication of an individual's nonverbal reasoning, spatial processing skills, attentiveness to detail, and visual-motor integration. The overall cognitive ability is estimated by the Full Scale IQ which is an aggregate of the Verbal and Performance IQ scores. The Processing Speed Quotient is an option for individuals aged 4 through 7 years and measures the speed of mental and graphomotor processing. The General Language Composite is obtained from individuals aged 2 years 6 months up to 3 years 11 months and it measures receptive and expressive vocabulary.

Wechsler Memory Scale, Third Edition (WMS-III)
The Wechsler Memory Scale, Third Edition (WMS-III) assesses an individual’s memory functioning. The WMS-III is organized into six sections: 1) Working Memory; 2) Ability to learn and retain new material; 3) Auditory Learning; 4) Modality-specific memory; 5) Retention of information; and 6) Retrieval of information. As defined by the WMS-III, learning refers to a person’s ability to encode and store novel information while memory refers to the persistence of learned material that can be retrieved after a brief (immediate) or long (delayed) interval. The WMS–III is intended to provide information regarding learning and memory under a specific set of conditions, but is not intended to provide direct information regarding academic achievement or to reflect the more general academic usage of the term ability to learn.

Wide Range Achievement Test -- Third Edition (WRAT3)
The Wide Range Achievement Test-Third Edition (WRAT3) is used to measure the codes which are needed to learn the basic skills of reading, spelling and arithmetic. Standard scores and grade scores are supplied for each of these three subtest areas. The WRAT3 was intentionally designed to eliminate the effects of comprehension. This helps clarify if the learning disability is based on comprehension or actual mechanics. Published by Jastak Wide Range Publishing.

Woodcock Johnson Tests of Achievement, Third Edition (WJ-III)
The Woodcock Johnson, Third Edition (WJ-III) consists of two co-normed batteries: Tests of Achievement and Tests of Cognitive Abilities. The two batteries assess general intellectual ability, specific cognitive abilities, oral language, and academic achievement. The tests can be used with a population ranging in age from 2 years to 80+ years. The achievement battery is available as a standard battery comprising 12 tests or an extended battery that has 10 tests that provide more in-depth diagnostic information on specific academic strengths and weaknesses. The achievement tests are primarily organized into five broad curricular areas: reading, oral language, mathematics, writing, and academic knowledge. The test is also available in two forms, Form A and Form B, which have parallel content. Published by Riverside Publishing. WWW.RIVERPUB.COM
