The Stanford-Binet Intelligence Scales - Fifth Edition (SB5) is an individually administered intelligence test for individuals ages 2 to 89 years old. It measures five cognitive factors: fluid reasoning, knowledge, quantitative reasoning, visual-spatial processing, and working memory. The SB5 contains 10 subtests administered adaptively based on performance. It provides scores for nonverbal IQ, verbal IQ, full scale IQ, and the five factors. The SB5 has good reliability and was standardized on a sample of 4800 individuals representative of the US population.

(SB5)

2. Measurement Area
• The Stanford-Binet Intelligence Scales – Fifth Edition (SB5) is
designed to test intelligence and cognitive abilities.
• This test can be used for ages 2 years 0 months to 89 years 11
months.
• The SB5 was based on Cattell-Horn-Carroll (CHC) theory of
intellectual abilities.
• The SB5 measures five CHC factors by different types of tasks
and subtests at different levels.

3. The SB5: 10 Subtests
• Contains many of the subtests of SB4 but they have been
altered/combined.
• Represents abilities assessed by all former versions of the test.
• The Fifth Edition reintroduces the age-scale format for the body of the
test.
• Intended to provide a variety of content to:
• Keep examinees involved in the testing experience
• Allow for the introduction of developmentally distinct items across levels

4. • The short-term memory was shifted over to a working
memory model
• The other subscales remained essentially the same except
• The addition of Visual/Spatial Reasoning
• And a few changes to the names of the subscales

7. Material
• The SB5 complete kit is sold by the publisher for USD
$1,087.00 and includes:
• Scoring software (SB5 Scoring Pro, Version 1.2) is available for
USD $255.00 and an interpretive manual is also available for
USD $121.00.
• 3 Item books • Examiners manual
• Technical manual • Child card
• Layout card • Manipulatives kit
• Storage box • 25 Record forms
• A carrying case

8. Accessibility
• Available in the English language using USA norms.
• Contains cautions for testing individuals who are English
language learners or English as a second language. This caution
is particularly crucial to the verbal items.
• Considerations and cautions are also noted for those with special
needs, or who are deaf or hard of hearing, have communication
disorders, orthopedic impairments, or motor skills deficits.

9. Administration, Scoring, and Interpretation
• Graduate-level or professional training in psychological
assessment
• Interpret test results using the 7 step method described in
the manual.
• The manual contains a section on basic score
interpretation. An interpretation manual is available from
the publisher.

10. Administration of Test
• Begins with the “Object Series/Matrices” subtest, used to assess non-
verbal fluid reasoning
• This subtest is also used as a “routing” test; the score on this test
determines where the examiner begins testing on the remaining non-
verbal subtests
• Has 36 items; uses colored plastic shapes, toys, blocks, then matrices
• Examiner begins at “the estimated ability level of the examinee
(usually the chronological age of the person)”

11. •Next subtest administered is the Vocabulary
subtest, used to assess Verbal Knowledge
•This subtest is used as a routing test for all
of the remaining verbal subtests
•Starts with an identification of facial
features, then toys, then pictures, then word
definitions

12. Adaptive Testing
• Stanford-Binet has always been an “adaptive” test
• Individual responds to only that part of the test that is appropriate for his or her
developmental level
• E.g., a young child is not given difficult problems that would only lead to
frustration; similarly, an older examinee is not bored with questions that are
too easy
• Each subtest starts with very easy items & progresses to items that are more
difficult

13. • Routing tests assist examiner to begin each subtest at an
appropriate level of difficulty for examinee
• All of the test items for the SB5 are contained in 3 item
books
• Item Book 1 contains the first two (routing) subtests
• After the second subtest has been administered, the
examiner has recorded estimated ability scores designed to
identify an appropriate start point in Item Books 2 & 3

14. • Examiner administers the next four nonverbal subtests of
an appropriate level determined from Book 2
• Examiner starts at appropriate start point, & if examinee
answers items correctly, this is assumed to be the “basal
level” of ability
• Continues until examinee answers incorrectly for a certain
number of items (this is the examinee’s “ceiling level” for
that subtest)

15. • Examiner then administers the final four verbal subtests
from Item Book 3, starting at appropriate level
determined from routing vocabulary test

16. scoring
 Points are summed for each of the subtests & converted to a “scaled
score”
• Scaled subtest scores have a mean of 10 & a standard deviation of
3
 Scores can also be computed for nonverbal IQ, verbal IQ, full-scale IQ
and each of the five factors (fluid reasoning, knowledge, quantitative
reasoning, visual-spatial processing, working memory)
• These “standard scores” have a mean of 100 & a standard
deviation of 15.

17. • During test, test user can also do behavioral observation:
• Examinee’s physical appearance, mood, activity level.
Current medications, and related also be noted in
behavioral observation
• How to cope with frustration • How to respond on easy items
• Amount of support needed • General approach to the task
• How anxious • How much fatigue
• How much cooperative • Distractible
• Compulsive

20. Psychometric Properties of SB5
 Suitable for age range of 2 to 85+ years of age
 Range of possible scores runs from a low of 40 to a high of 160
 Reliability coefficients are as follows:
• Full scale IQ - .98
• Nonverbal & verbal - .95 to .96
• Factor scores - .90 to .92
 Test-retest reliabilities range from high .7’s to low .9’s depending
on age & testing interval

21. Standardization
• The SB5 was normed and standardized using an American sample of
4800 individuals (51% female, 49% male) ages 2 to 85+ years.
• Some 500 examiners from all 50 states were trained to administer the
test.
• The sample was stratified according to demographic variables such as
age, sex, race/ethnicity, SES level and geographic region.
• Demographic information is based on the 2001 United States Census
bureau data.

22. • No accommodations were made for persons wit
special needs in the standardization sample, although
such accommodations were made in separate studies.
• Persons were excluded from the standardization
sample (although included in separate validity
studies) if they had limited English proficiency,
severe medical conditions, severe sensory or
communication deficits, or severe emotional/behavior
disturbance (Roid, 2003).

23. Advantages of SB5
• More game like than earlier versions with colorful artwork, toys, and
manipulatives.
• Matches norms to 2000 U.S. Census.
• Contains nonverbal as well as verbal routing test.
• Contains both a general composite score and several factor scores.
• Shares items to maintain continuity with earlier versions.
• Covers age range of 2-0 through 85+.

24. Cont…
• Change-sensitive scores allow for evaluation of extreme performance.
• Has easel format with directions, scoring criteria, and stimuli, for easy
administration.
• Has equal balance of verbal and nonverbal content in all factors.
• Contains Nonverbal IQ.
• Has standard deviation of 15 for composite scores, allowing easy
comparison with other tests; M = 10, SD = 3 for subtests.

25. Cont…
• Uses adaptive testing (routing) to economize on administration time
and reduce examinee frustration.
• Uses explicit theoretical framework as guide for item development
and alignment of subtests within modeled hierarchy.
• Extends low-end items, allowing earlier identification of individuals
with delays or cognitive difficulties.
• Extends high-end items to measure gifted adolescents and adults.

26. Binet’s Warnings About Possible Misuse of
Intelligence Testing
1) Do not and should not be used to measure innate intelligences.
2) Intelligence testing should not be used to label individuals.
“the important concern is to describe the examinee’s skills and
abilities in detail, going beyond the label itself” (Roid, 2003c)
