Five factors, asked two ways.

The SB5 was the first intellectual battery to measure five cognitive factors in both a verbal and a nonverbal form. The result is ten subtests, for ages 2 to 85 and over.1

ABIQ
Abbreviated Battery IQ.Just the two routing subtests: Object Series/Matrices (nonverbal) and Vocabulary (verbal). It gives a quick estimate of fluid reasoning and crystallized ability.2

IQs and factor scores have a mean of 100 and SD of 15, with a possible range of 40 to 160. Subtest scaled scores have a mean of 10 and SD of 3.6

A century of Binets

Each edition changed how scores were calculated.4,8

1905Binet-SimonThe first systematic cognitive test; mental age
1916Terman, StanfordUS adaptation; the ratio IQ
1937Terman & MerrillTwo parallel forms, L and M
1960Form L-MDeviation IQ (mean 100, SD 16)
1986Fourth editionThorndike, Hagen & Sattler; point scales, four areas
2003SB5Roid; five factors, verbal and nonverbal, CHC-based

One source lists a 2016 "sixth edition", but another says a sixth edition is still to come, and the SB5 is described as the only edition in clinical use. It isn't included above.8,9,4

Reliability coefficients (bars span .85–1.00)6
The norm sample of 4,800 was aged 2 to 96, matched to 2001 US census figures; the oldest norm group is 85+.1
The body of the test reintroduces the age-scale format of early Binets.6
Its factor model was redesigned around the Cattell-Horn-Carroll (CHC) framework.7
Its adaptive administration and high ceiling make it especially valued for identifying gifted children.3
One source gives the age range as 2 to 89, and another names ProEd rather than Riverside as publisher.6
