Stanford-Binet 5 (SB5): Current Stanford-Binet edition

The current Stanford-Binet (5th edition, 2003). Five factors (Fluid Reasoning, Knowledge, Quantitative Reasoning, Visual-Spatial Processing, Working Memory) measured in both Verbal and Nonverbal domains. Ages 2 to 85+. Strong measure across the full IQ range, particularly useful for very low and very high IQ assessment.

About the Stanford-Binet 5 (SB5)

Stanford-Binet 5 (SB5, 2003) is the current edition of the venerable Stanford-Binet, now under Gale Roid's revision (Lewis Terman published the original 1916 and revised 1937 editions). SB5 measures 5 cognitive factors derived from CHC theory: Fluid Reasoning (Gf), Knowledge (Gc), Quantitative Reasoning (Gq), Visual-Spatial Processing (Gv), Working Memory (Gsm). Each factor is measured in both Verbal and Nonverbal domains for a 5x2 = 10-subtest core battery.

SB5 produces 8 composite scores: Full Scale IQ, Verbal IQ, Nonverbal IQ, and one IQ for each of the 5 factors. The norm sample of 4,800 individuals aged 2 to 85+ years is among the largest IQ norm samples ever collected. The test has excellent measurement at the extreme low and high ends of the IQ distribution.

SB5 is particularly used for: gifted assessment (good ceiling for IQ 150+), intellectual disability diagnosis (good floor for IQ 40-), assessment of clients with limited English (nonverbal subtests work language-free), and longitudinal studies that continue the historical Stanford-Binet lineage.

Sample Items (Illustrative)

Items are presented in a mix of verbal and nonverbal formats, with responses scored based on accuracy and adherence to the task instructions. Some items may be multiple-choice, while others require short constructed responses.

Sample 1 · Fluid Reasoning (Gf) - Verbal
What is the next number in the sequence: 2, 4, 8, 16, ...?
Example response: 32
Sample 2 · Knowledge (Gc) - Nonverbal
Point to the picture that shows a historical event.
Example response: The image depicting the signing of the Declaration of Independence.
Sample 3 · Quantitative Reasoning (Gq) - Nonverbal
Look at the shapes. If a triangle equals 3, a square equals 4, and a circle equals 5, what is the total value of two triangles and one circle?
Example response: 11
Sample 4 · Visual-Spatial (Gv) - Nonverbal
Rearrange these blocks to match the pattern shown in the picture.
Example response: The blocks are arranged to form a 3x3 grid with alternating colors.
Sample 5 · Working Memory (Gsm) - Verbal
Listen to this list of words: apple, car, house, tree. Now repeat them back to me in reverse order.
Example response: tree, house, car, apple

These are illustrative samples, not actual items from the protected test.
