Inventory for testing cognitive capabilities

Please note that this product can only be administrated if you have an online VTS Basic Subscription or a local VTS version from 8.13.00 or higher.

Field of Application+

Detailed Description+

Measures general cognitive ability and specific performance indicators for logical-, verbal and numerical reasoning as well as visual-spatial ability.

The main areas of application of the INT are the areas of staff & management assessments, jobs & career placement, safety & security, and academic testing.

Test forms+

Two test forms are available. They differ regarding the presentation of the item material and the content of the item. The item material of the test forms does not overlap.

The test form S1 consists of four subtests and is intended only for supervised administration. The items are presented linearly.

The standard form S2 consists of four subtests and can be used for testing without supervision. The items of the test form can be presented in linear, randomized or adaptive form.


In the subtest Logical Reasoning the respondent’s task is to select a field from an item with nine fields that does not follow the same rules as the other eight fields.

In the subtest Numerical Ability the respondent is shown equations without any arithmetical signs. The respondent's task is to select the arithmetical signs so that the equation is correct.

The task in the Verbal Ability subtest is to correctly recognize and apply lexical relations.

In the subtest Visual-spatial ability the respondent is shown an object from two different perspectives. The respondent's task is to correctly recognize from which perspective the start view needs to be looked at to be identical to the target view.

The following main variables are scored:

General cognitive ability: A measure for the ability to recognize patterns, understand implications, and to deduce logical inferences from figurative, verbal, numerical item or visual-spatial material.

Logical reasoning: A measure of the ability to solve new problems using inductive thinking processes.

Verbal reasoning: A measure for the ability to understand the meaning of words and their underlying concepts, to relate them to one another, and to draw conclusions from them.

Numerical reasoning: The knowledge of basic arithmetical operations as well as the ability to derive mathematical solutions from them.

Visual-spatial ability: The ability to picture objects spatially in one's mind and rotate them mentally.

The main variables are calculated as factor scores based on the results of confirmatory factor analyses. In addition, the corresponding norm-referenced score including the confidence interval is also reported.
