Normative data for the SB5 were gathered from 4,800 individuals aged 2 to 85+. The normative sample closely matches the 2000 U.S. Census. Bias reviews were conducted on all items for gender, ethnicity, culture, religion, region, and socioeconomic status. Additionally, the SB5 was co-normed with the Bender® Visual-Motor Gestalt Test, Second Edition.
Reliabilities for the SB5 are very high. For the FSIQ, NVIQ, and VIQ, reliabilities range from .95 to .98 . Reliabilities for the Factor Indexes range from .90 to .92. For the 10 subtests, reliabilities range from .84 to .89.Back to the top
