Stanford-Binet Intelligence Scales, Fifth EditionCATEGORIES: Ability PURPOSE: An individually administered assessment of intelligence and cognitive abilities AUTHORS: Gale Roid, 2003, 5th Edition RANGE: Age 2 to 85+ years ADMINISTRATION TIME: varies, approximately 5 minutes per subtest Note: SB-IV Record Booklets are available for the previous edition. See the components chart at the bottom of page.
SUMMARYNew! Early SB5 kits are available for younger subjects, to age 7-0 (more information below) The Stanford-Binet Intelligence Scale, Fifth Edition (SB5) is a contemporary assessment with a rich tradition, which began in 1916 when Lewis Terman completed his American revision of the Binet-Simon Scales (1908). Through various editions, this assessment has become widely known and is acknowledged as the standard for intelligence measurement. The SB5 is a valuable update to this well-established assessment. The SB5 blends many of the important features of earlier editions with significant improvements in psychometric design. It incorporates the use of two routing subtests in the point-scale format of the 1986 edition with the functional-level design of the 1916 to 1960 editions for the remaining subtests. Modern item response theory provides a strong psychometric foundation for the routing, subtests, and functional-level design. By adapting the test to the functional level of the examinee, the routing procedure of the SB5 increases the precision of measurement by tailoring the difficulty of the items to his or her level of cognitive functioning. The use of a hierarchical model of intelligence with a global g factor and several broad factors at a second level is repeated in this edition. RESOURCES
FEATURESThe SB5 is appropriate for a broad range of 2 to 85+ years, providing one assessment for all ages. It provides comprehensive coverage of five factors of cognitive ability:
Psychologists will appreciate the new features of the SB5:
USESThe SB5 may be used to diagnose a wide variety of developmental disabilities and exceptionalities and may also be useful in:
ADMINISTRATIONTesting begins in Item Book 1 with the routing subtests. The start points for two routing subtests in Item Book 1 are determined by age or estimated ability level; Nonverbal Fluid Reasoning routes to the appropriate difficulty level in Item Book 2 (Nonverbal), while Verbal Knowledge does so for Item Book 3 (Nonverbal). The remaining eight subtests (four nonverbal and four verbal) are then measured in Item Books 2 and 3.
SCORING AND INTERPRETATIONThe SB5 can be hand-scored or scored with optional scoring software. At the most granular level of the norm-referenced scores are the ten subtest scores (scaled scores have a mean of 10, SD=3, score range 1-19). These subtest scores combine to form four types of composite scores: factor index, domain, abbreviated, and full scale (each with scaled score means of 100, SD=15, score range 40-160). Two subtests (one verbal, the other its nonverbal complement) combine to form each factor index. There are two domain scales: Nonverbal IQ (combines the five nonverbal subtests) and Verbal IQ (combines the five verbal subtests). Two routing subtests combine to form the Abbreviated Battery IQ. Finally, the Full Scale IQ combines all ten subtests. The Change-Sensitive Scores (CSSs) use item response theory scaling to convert the raw score totals on the composite scales described above into criterion-referenced levels of ability. These scales, as with the norm-referenced scores, have excellent measurement properties. Because the CSSs reference absolute levels of ability, they provide a means to compare changes in an individual's scores over time. Scores range from the 2-year-old level (about 430) to the adult level (about 520). All of the SB5 items have been calibrated to this scale, and the difficulty of each item has a location along that scale. The scores will be particularly useful for the evaluation of extreme performance levels. The SB5 also offers age-equivalent scores derived from CSSs, along with a CSS-based abbreviated battery score making use of raw scores from the Nonverbal Reasoning and Verbal Knowledge subtests. Finally, the Interpretive Manual describes a hand-scoring procedure for deriving an extended Full Scale IQ score that allows for scores below 40 and above 160. A variety of intepretive frameworks can be applied to the results of this test. Refer to the Examiner's Manual, Interpretive Manul, or the SB5 Scoring Pro software for guidance on interpretation. TECHNICAL QUALITIESNormative data for the SB5 were gathered from 4,800 individuals between the ages of 2.0 and 85+ years. The normative sample closely matches the 2000 U.S. Census (education level based on 1999 data). Bias reviews were conducted on all items for the following variables: gender, ethnicity, cultural, religion, region, and socio-economic status. Additionally, the SB5 was co-normed with the Bender-Gestalt Visual-Motor Gestalt Test, 2nd Edition. Reliabilities for the SB5 are very high. For the FSIQ, NVIQ, and VIQ, reliabilities range from .95 to .98 (average internal consistency composite reliability, across all age groups).Reliabilities for the Factor Indexes range from .90 to .92. For the ten subtests, reliabilities range from .84 to .89. Concurrent and criterion validity data was obtained using the:

SB5 SCORING PRO SOFTWAREThe SB5 Scoring Pro is a Windows-based software program that replicates the process of hand-scoring - users enter background information, age, and raw scores. This program provides consistency in raw score conversion, an extended score report, a graphical report, and a brief, narrative summary report with guidelines and suggestions based on well-established principles of assessment. The report can be exported and then imported to a word processing file for editing as necessary. Minimum System Requirements: Windows 98 / NT4.0 / ME / 2000 / XP, Pentium 200 MHz processor, 64 MB RAM (96 MB recommended), CD-ROM or DVD drive, SVGA monitor (.NET-compatible video card), 100 MB free hard disk space INTERPRETIVE MANUALThe Interpretive Manual provides detailed guidelines for the effective interpretation of the Fifth Edition of the Stanford-Binet for a number of applications, including its use by psychologists active in school, clinical, and counselling settings. Case studies, profile analyses, and SB5 Scoring Pro 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 or higher than 160. SB5 UNIVERSITY TRAINING RESOURCESThe SB5 University Training Resources contains a CD-ROM with a PowerPoint presentation, along with PDF documents for Tips for Examiners, Frequently Asked Questions, selected Assessment Service Bulletins, and other resources. This package is designed for use by university professors and training professionals to help teach others the use of the SB5. EARLY SB5 -- ESPECIALLY FOR YOUNGER SUBJECTS -- NEWFor examiners who specialize in younger subjects, to age 7-0, the Early Stanford-Binet Fifth Edition (Early SB5) is a perfect match. Please refer to the Early SB5 section in the components table below.
