The SB5 provides comprehensive coverage of five factors of cognitive ability: fluid reasoning, knowledge, quantitative reasoning, visual-spatial processing, and working memory.

Predictive scores help identify potential disabilities

  • Advances the assessment of strengths and weaknesses in the cognitive processes of students; information on special predictive composite scores for identifying disabilities in both reading and math is available in the Interpretive Manual.
  • Helpful in diagnosing a wide variety of developmental disabilities and exceptionalities and also may be useful in clinical and neuropsychological assessment, early childhood assessment, psychoeducational evaluations for special education placements, and more.

Useful for assessing a wide range of clients

  • Enhanced nonverbal/low-verbal content requires minimal or no verbal responses from the examinee.
  • Useful in assessing LEP/ELL, deaf and hard-of-hearing, and autistic populations.
  • Extensive high-end items measure the highest levels of gifted performance, while improved low-end items better measure low functioning children and adults.
  • Ideal for measuring basic psychological processes in problem-solving models like RTI.

Psychometrically sound and well normed

  • Normative data for the SB5 were gathered from 4,800 individuals whose demographics closely matched those of the U.S. Census.
  • Reliabilities for the Full Scale IQ, Nonverbal IQ, and Verbal IQ 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 10 subtests, reliabilities range from .84 to .89.
  • Concurrent and criterion validity data were obtained using the SB-IV, SB-LM, WJ® III, UNIT™, Bender®-Gestalt II, WPPSI® R, WAIS®-III, WIAT®-II, and WISC®-III.
