The Intelligence Structure Test (IST) is an intelligence test battery with a broad range of applications based on the structural model of intelligence.
Each area of intelligence is assessed through three sub-tests.
The inclusion of three sub-tests in each area means that several different types of item are used to measure each area. Thus the battery avoids the error of simply equating one particular type of item with an individual area of ability.
When all nine sub-tests are administered together, an overall score for reasoning is computed along with separate scores for each ability area and the sub-tests within that area. Sub-tests can also be administered individuallywith completion times ranging from 6-10 minutes.
This version of IST contains the verbal, numerical and figural/spatial ability modules:
The following additional components of the complete battery are currently being developed for the UK edition:
The complex structure on which the battery is based is reported in Beauducel, Brocke and Liepmann (2001) and Liepmann, Beauducel, Brocke and Amthauer (2007). The full battery also differentiates fluid intelligence and crystallised intelligence. The IST thus allows intellectual abilities to be assessed in a contemporary and well-differentiated manner.
