The Stanford-Binet Intelligence Test
The Stanford-Binet Intelligence Scale is a widely used, individually administered intelligence
test. It's a revision of the original Binet-Simon Scale, and the current version is the Fifth Edition
(SB5), released in 2003.
The SB5 is used to assess an individual's overall intellectual ability and is often used in clinical,
neuropsychological, and psychoeducational evaluations.

The Stanford-Binet Intelligence Scales, Fifth Edition (SB5) is the latest version of the
Stanford-Binet test, released in 2003. It represents a significant update from its predecessors,
emphasizing modern theories of intelligence and improving its applicability across a broader age
range and more diverse populations.
Developed by Gale H. Roid and R. Andrew Barram
Key Features of SB5: Age Range:
Suitable for ages 2 to 85+ years.
Measurement Domains: SB5 assesses five major cognitive abilities, with both verbal and
nonverbal subtests for each:
Fluid Reasoning (FR): Problem-solving and novel reasoning (e.g., analogies, pattern analysis).
Knowledge (KN): Accumulated information and skills (e.g., vocabulary, general information).
Quantitative Reasoning (QR): Numerical problem-solving (e.g., math concepts, number
series).
Visual-Spatial Processing (VS): Understanding visual patterns and relationships (e.g., puzzles,
spatial reasoning).
Working Memory (WM): Holding and manipulating information (e.g., short-term memory,
sequencing).
Applications:
• Educational placement and assessment
• Identification of intellectual disabilities or giftedness
• Psychological and neuropsychological evaluations

• Ceiling Age The lowest year level at which the examinee fails all the subtests of the
scale.
• Mental Age Mental age is computed by adding to his basal age, the number of months
credit received for passing each subtest up to his ceiling age.
• Chronological Age is the actual age of the person based on their birthdate,
• Basal Age represents the highest level, on a test standardized in units corresponding to
mental age or age-equivalents, below which it can be assumed that all items would be
answered correctly.
• Age equivalents. refer to the estimated mental age or developmental age based on
performance on specific subtests or items.
• IQ-The full form of IQ is Intelligence Quotient. IQ is an overall score obtained from a
series of standardized measures or subtests designed to measure individual intelligence.
