The Stanford-Binet Intelligence Scales-Fifth Edition (SB5) can be used to measure intelligence/cognitive ability from the ages of 2-85+ years.
The collection of 10 subtests, providing Nonverbal, Verbal, and Full Scale IQ scores and other diagnostic indexes, offers highly reliable assessment of intellectual and cognitive abilities, based on a large normative sample. The SB5 provides a comprehensive profile of scores to document the cognitive strengths and weaknesses of children, adolescents, and adults with learning difficulties, delays, and disabilities.
The SB5 may only be administered by hand, but can be scored online via the SB5 Online Scoring and Report System (hand-scoring may also be conducted).
The SB5 Interpretive Manual provides detailed guidelines for the effective interpretation of the SB5 for a number of applications, including its use by psychologists active in school, clinical, and counselling settings.
Case studies, profile analyses, and SB5 Scoring reports provide concrete examples of interpretation. This manual also introduces an Extended IQ (EXIQ) scale that supports the calculation of Full Scale IQ scores substantially lower than 40 (e.g., to an IQ of 10) or higher than 160 (to an IQ of 225).
